Passionfruit

Botanical Name:Passiflora edulis
Family:Passifloraceae
Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Malpighiales
Genus: Passiflora
Species: P. edulis

Other Names: Passiflora edulis, passion fruit.It is locally called Sohbrab in Meghalaya in India
Habitat: It is native to South America and widely grown in India, New Zealand, the Caribbean, Brazil, Ecuador, California, southern Florida, Hawaii, Australia, East Africa, Israel and South Africa. It’s cultivation has been extended to some areas of North-eastern region like Mizoram, Manipur, Nagaland and Sikkim.

Description:
The purple passion fruit (P. edulis) is a woody perennial vine with robust climber. The stems, tendrils and leaves are clear green without any trace of reddish or pinkish colour. The fruit is round or oval, 3 to 5 cm in diameter and deep purple when ripe. The yellow passion fruit (P. edulis f. flavicarpa) vine is much like that of the purple variety but is a more vigorous grower. It is distinguished by the suffusion of reddish, pinkish or purplish colour in stems, leaves and tendrils.The flowers have the scent of heliotropes.

The passion fruit is round to oval, yellow or dark purple at maturity, with a soft to firm, juicy interior filled with numerous seeds. The fruit can be grown to eat or for its juice, which is often added to other fruit juices to enhance aroma.

The two types of passion fruit have greatly different exterior appearances. The bright yellow variety of passion fruit, which is also known as the Golden Passionfruit, can grow up to the size of a grapefruit, has a smooth, glossy, light and airy rind, and has been used as a rootstock for the purple passion fruit in Australia. The dark purple passion fruit (for example, in Kenya) is smaller than a lemon, with a dry, wrinkled rind at maturity.

The purple varieties of the fruit reportedly have traces of cyanogenic glycosides in the skin, and hence are mildly poisonous. However, the thick, hard skin is hardly edible, and if boiled (to make jam), the cyanide molecules are destroyed at high temperatures.

Cultivation details:
Requires a well-drained soil with plenty of moisture in the growing season, otherwise it is not fussy.

Plants are not very frost tolerant and are best grown in a greenhouse. However, the roots are somewhat hardier and can survive the winter outdoors in many areas of Britain if the soil is prevented from freezing. If plants are cut down to the ground by frost they can regenerate from the base. There is also the possibility of growing plants on rootstocks of P. caerulea which might make them hardier.

This species is often cultivated in warmer climes than Britain for its edible fruit, there are some named varieties. The fruit can be freely produced in Britain in hot summers.

Roots of outdoor grown plants should be restricted to encourage fruiting.

Any pruning is best carried out in the spring.

If fruit is required it is best to hand pollinate, using pollen from a flower that has been open for 12 hours to pollinate a newly opened flower before midday. The flowers open in sunny weather and do not open on dull cloudy days. The flowers have the scent of heliotropes.

A climbing plant, attaching itself to other plants by means of tendrils that are produced at the leaf axils.

Plants in this genus are notably resistant to honey fungus.
Propagation:
Pre-soak the seed for 12 hours in warm water and then sow late winter or early spring in a warm greenhouse. If sown in January and grown on fast it can flower and fruit in its first year[88]. The seed germinates in 1 – 12 months at 20°c. Prick out the seedlings into individual pots when they are large enough to handle. It you are intending to grow the plants outdoors, it is probably best to keep them in the greenhouse for their first winter and plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Mulch the roots well in late autumn to protect them from the cold.

Cuttings of young shoots, 15cm with a heel, in spring.

Leaf bud cuttings in spring.

Cuttings of fully mature wood in early summer. Takes 3 months. High percentage.

Uses
*A glass of passion fruit juiceIn Australia, it is available commercially fresh and canned. In addition to being added to fruit salads, passion fruit is commonly used in desserts, such as the topping for the pavlova (a meringue cake), cheesecake, and vanilla slice. It is also used to flavour soft drinks such as Passiona and cordials.

*In the Dominican Republic, it is used to make juice, jams, the chinola flavoured syrup is used on shaved ice and it is also eaten raw sprinkled with sugar.

*In Puerto Rico, where its called Parcha, it is widely believed to lower blood pressure. This is probably because it contains harmala alkaloids and is a mild RIMA.

*In Brazil, passion fruit mousse is a common dessert, and passion fruit seeds are routinely used to decorate the tops of certain cakes. Passion fruit juice is also very common.

*In Indonesia it is eaten straight as a fruit. Nevertheless, it is common to strain the passionfruit for its juice and cook it with sugar to make some sort of thick syrup. It is then mixed with water and ice to be drunk.

*In Hawaii, where it is called lilikoi, it is normally eaten raw. Hawaiians usually crack the rind of the lilikoi either with their hands or teeth and suck out the flavorful pulp and seeds. Lilikoi can also be cut in half and the pulp can easily be scooped out with a spoon. Lilikoi flavoured syrup is a popular topping for shave ice. Ice cream and mochi are also flavoured with lilikoi, as well as many other desserts such as cookies, cakes, and ice cream. Lilikoi is also favored as a jam, jelly, as well as a butter. Lilikoi fruits are not widely available in stores, so most of the fruit eaten comes from backyard gardens or wild groves. They however can be found in farmers markets sprinkled throughout the islands.

*Passion fruit juice or syrup is an essential ingredient of some cocktails, particularly the hurricane and the Peruvian maracuya sour.

*In South Africa passion fruit is used to flavor yogurt. It is also used to flavour soft drinks such as Schweppes Sparkling Granadilla and numerous cordial drinks.

Passion fruit juice can be boiled down to a syrup, which is used in making sauce, gelatin desserts, candy, ice cream, sharbat, cake icing, cake filling, etc. There is a preference for the purple variety as fresh fruit and the yellow one for juice-making.

Nutrition
Fresh Passion Fruit is known to be high in vitamin A, Potassium and dietary fibre. The Yellow variety is used for juice processing, while the Purple variety is sold in fresh fruit markets. Passion fruit juice is a good source of ascorbic acid (vitamin C).
Medicinal Uses: There is currently a revival of interest in the pharmaceutical industry, especially in Europe, in the use of the glycoside, passiflorine, especially from P. incarnata L., as a sedative or tranquilizer. Italian chemists have extracted passiflorine from the air-dried leaves of P. edulis.

The pulp of the fruit is stimulant and tonic.
In Madeira, the juice of passionfruits is given as a digestive stimulant and treatment for gastric cancer.

Noni

Wild noni growing in Kuliouou Valley'', Hawaii
Image via Wik

Botanical Name:Morinda citrifolia
Family: Rubiaceae

Kingdom: Plantae
Division: Magnoliophyta
Class: Magnoliopsida
Order: Gentianales
Genus: Morinda
Species: M. citrifolia
Common Names:commonly known as great morinda, Indian mulberry, beach mulberry, Tahitian noni, cheese fruit or noni (from Hawaiian) is a tree in the family Rubiaceae.
Habitat: Morinda citrifolia is native to Southeast Asia but has been extensively spread throughout the Indian subcontinent, Pacific islands, French Polynesia, and recently the Dominican Republic. Tahiti remains the most prominent growing location.

Description:

It grows to a height of up to 10 feet high, and the leaves are dark green and oval shaped. The flower heads grow to become mature yellow fruit that have a strong odor.

Click to see the picture of the fruit
Noni grows in shady forests as well as on open rocky or sandy shores. It reaches maturity in about 18 months and then yields between 4-8 kg of fruit every month throughout the year. It is tolerant of saline soils, drought conditions, and secondary soils. It is therefore found in a wide variety of habitats: volcanic terrains, lava-strewn coasts, and clearings or limestone outcrops. It can grow up to 9 m tall, and has large, simple, dark green, shiny and deeply veined leaves.

The plant flowers and fruits all year round and produces a small white flower. The fruit is a multiple fruit that has a pungent odor when ripening, and is hence also known as cheese fruit or even vomit fruit. It is oval and reaches 4-7 cm in size. At first green, the fruit turns yellow then almost white as it ripens. It contains many seeds. It is sometimes called starvation fruit. Despite its strong smell and bitter taste, the fruit is nevertheless eaten as a famine food and, in some Pacific islands, even a staple food, either raw or cooked. Southeast Asians and Australian Aborigines consume the fruit raw with salt or cook it with curry. The seeds are edible when roasted.

The noni is especially attractive to weaver ants, which make nests out of the leaves of the tree. These ants protect the plant from some plant-parasitic insects. The smell of the fruit also attracts fruit bats, which aid in dispersing the seeds.

Propagation of Noni
Noni is propagated either from seed or stem cuttings. The primary disadvantage of seed propagation is that without seed treatment, germination takes 6-12 months or more, whereas stem cuttings can be rooted in approximately 1-2 months. The disadvantage of producing plants vegetatively from cuttings is that they may not be as strong and disease-resistant as seedlings, and the trunk and branches may split and break during the first years of fruit production.

Nutrients
Nutritional information for noni fruit is reported by the College of Tropical Agriculture, University of Hawaii at Manoa who published analyses of fruit powder and pure juice.

Macronutrients
Analyzed as a whole fruit powder, noni fruit has excellent levels of carbohydrates and dietary fiber, providing 55% and 100% of the Dietary Reference Intakes (DRI), respectively, in a 100 g serving. A good source of protein (12% DRI), noni pulp is low in total fats (4% DRI]).

These macronutrients evidently reside in the fruit pulp, as noni juice has sparse amounts of macronutrients.

Micronutrients
The main micronutrient features of noni pulp powder include exceptional vitamin C content (10x DRI) and substantial amounts of niacin (vitamin B3), iron and potassium. Vitamin A, calcium and sodium are present in moderate amounts.

When noni juice alone is analyzed and compared to pulp powder, only vitamin C is retained at a high level, 42% of DRI.

Nutrient analyses for a major brand of noni juice (Tahitian Noni Juice, TNJ) were published in 2002 by the Scientific Committee on Food of the European Commission on Health and Consumer Protection during a test for public safety of TNJ. TNJ ingredients include noni purée and juice concentrates from grapes and blueberries.

For antimicrobial purposes, TNJ must be subjected to the high temperatures of pasteurization which essentially nullifies most of the nutrient content of the natural purée.

Excepting vitamin C content at 31% of DRI in each 100g, TNJ has limited nutritional content. 100g of juice provides 8% of the DRI for carbohydrates, only traces of other macronutrients and low or trace levels of 10 essential vitamins, 7 essential dietary minerals and 18 amino acids.

Although the most significant nutrient feature of noni pulp powder or juice is its high vitamin C content, this level in TNJ provides only about half the vitamin C of a raw navel orange. Sodium levels in TNJ (about 3% of DRI) are multiples of those in an orange. Although the potassium content appears relatively high for noni, this total is only about 3% of the Recommended Dietary Allowance and so would not be considered excessive. TNJ is otherwise similar in micronutrient content to a raw orange.

Phytochemicals
The history of published medical research on noni phytochemicals numbers only around a total of 120 reports which began appearing in the 1950s. Just since 2000, over 100 publications on noni have been published in medical literature (reviewed in August 2007), defining a relatively young research field. Noni research is at a preliminary stage, as it is mainly still in the laboratory as in vitro or basic animal experiments.

Noni fruit contains phytochemicals for which there are no established DRI values. Examples:

lignans – a group of phytoestrogens having biological activities shown by in vitro experiments.
oligo- and polysaccharides – long-chain sugar molecules that serve a prebiotic function as dietary fiber fermentable by colonic bacteria, yielding short chain fatty acids with numerous potential health properties not yet defined by scientific research on noni

flavonoids – phenolic compounds such as rutin and asperulosidic acid, common in several Rubiaceae plants
iridoids – secondary metabolites found in many plants
trisaccharide fatty acid esters, “noniosides” – resulting from combination of an alcohol and an acid in noni fruit
free fatty acids –
most prominent in noni fruit are caprylic and hexanoic acids, responsible for unique pungent (cheese-like) aroma of ripe noni fruit.
scopoletin – may have antibiotic activities; research is preliminary
catechin and epicatechin.
beta-sitosterol – a plant sterol with potential for anti-cholesterol activity not yet proven in human research
damnacanthal – a potentially toxic anthraquinone, putatively an inhibitor of HIV viral proteins
alkaloids – naturally occurring amines from plants. Some internet references mention xeronine or proxeronine as important noni constituents. However, as no reports on either of these substances exist in published medical literature, the terms are scientifically unrecognized. Further, chemical analysis of commercially processed juice did not reveal presence of any alkaloids.

Although there is evidence from in vitro studies and laboratory models for bioactivity of each of the above phytochemicals, the research remains at best preliminary and too early to conclude anything about human health benefits provided by noni or its juice. Furthermore, these phytochemicals are not unique to noni, as nearly all exist in various plant foods.

Laboratory experiments demonstrated that dietary noni juice increased physical endurance in mice. A pilot study in distance runners showed increased endurance capacity following daily intake of noni juice over three weeks, an effect the authors attributed to increased antioxidant status.

Uses:

Although noni’s reputation for uses in folk medicine extends over centuries, no medical applications as those discussed below have been verified by modern science.

In China, Samoa, Japan, and Tahiti, various parts of the tree (leaves, flowers, fruits, bark, roots) serve as tonics and to contain fever, to treat eye and skin problems, gum and throat problems as well as constipation, stomach pain, or respiratory difficulties. In Malaysia, heated noni leaves applied to the chest are believed to relieve coughs, nausea, or colic.

The noni fruit is taken, in Indochina especially, for asthma, lumbago, and dysentery. As for external uses, unripe fruits can be pounded, then mixed with salt and applied to cut or broken bones. In Hawaii, ripe fruits are applied to draw out pus from an infected boil. The green fruit, leaves and the root/rhizome have traditionally been used to treat menstrual cramps and irregularities, among other symptoms, while the root has also been used to treat urinary difficulties.

The bark of the great morinda produces a brownish-purplish dye for batik making; on the Indonesian island of Java, the trees are cultivated for this purpose. In Hawaii, yellowish dye is extracted from its root in order to dye cloth. The fruit is used as a shampoo in Malaysia, where it is said to be helpful against head lice.

There have been recent applications also for the use of oil from noni seeds. Noni seed oil is abundant in linoleic acid that may have useful properties when applied topically on skin, e.g., anti-inflammation, acne reduction, moisture retention.

In Surinam and some other countries, the tree serves as a wind-break, as support for vines and as shade for coffee trees.

In traditional Polynesian medicine, noni (Morinda citrifolia) fruit has been used for many health conditions, such as constipation, diarrhea, skin inflammation, infection, and mouth sores. It has an unpleasant odor and taste, so it is believed to be a last resort fruit by many cultures. Manufacturers today sweeten noni juice to improve the taste.

Traditionally, the leaves of the noni tree were used topically for healing wounds.

Noni juice, like the juice of many other fruits, is a source of vitamins, minerals and antioxidants. The antioxidants may help to prevent certain diseases and help slow age-related changes in the body.

Animal studies evaluating the effects of noni suggest that it may have anti-cancer, pain-relieving, and immune system-enhancing effects. However, these studies mostly used extremely high doses that would be difficult to obtain from taking the juice. More importantly, there’s insufficient reliable evidence about the safety or effectiveness of noni for any health condition in humans.

Noni is heavily promoted for a very wide variety of conditions, such as arthritis, atherosclerosis, bladder infections, boils, bowel conditions, burns, cancer, chronic fatigue syndrome, circulatory weakness, colds, cold sores, constipation, diabetes, drug addiction, eye inflammation, fever, fractures, gastric ulcers, gingivitis, headaches, heart disease, hypertension, improved digestion, immune weakness, indigestion, kidney disease, malaria, menstrual cramps, menstrual disorders, mouth sores, respiratory disorders, ringworm, sinusitis, skin inflammation, sprains, strokes, thrush, and wounds. There is no real evidence, however, that noni is effective for these conditions.

The Noni tree produces a tropical fruit that helps the body heal itself. For over 2000 years, Pacific Islanders have used the juice of the Noni fruit to improve their health in a multitude of ways. Western researchers have begun to confirm this ancient wisdom.

Safety:
There are no formally established side effects of noni juice. Due to the lack of evidence, noni should not be used by pregnant or nursing women, children, or people with liver or kManageidney disease.

Noni juice is high in potassium, so it should be avoided by people with kidney disease or those taking ,potassium-sparing diuretics, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers, because it may result in hyperkalemia, the dangerous elevation of potassium levels.

Some Fruit Juices Lower Drug Effect

Grapefruit, orange and apple juices can harm the body’s ability to absorb certain medications and make the drugs less effective, said a study.

The research showed that these juices can decrease the effectiveness of certain drugs used to treat heart disease, cancer, organ-transplant rejection and infection, “potentially wiping out their beneficial effects”, it said.

David Bailey, a professor of clinical pharmacology with the University of Western Ontario and leader of the study, was the first researcher to identify grapefruit juice‘s potential to increase the absorption of certain drugs two decades ago, possibly turning some doses toxic.

The new findings came as part of his continuing research on the subject, and were presented at the 236th annual meeting of the American Chemical Society on Philadelphia, Pennsylvania.

“Recently, we discovered that grapefruit and these other fruit juices substantially decrease the oral absorption of certain drugs undergoing intestinal uptake transport,” said Bailey. “The concern is loss of benefit of medications essential for the treatment of serious medical conditions.”

Healthy volunteers took fexofenadine, an antihistamine used to fight allergies, along with either a glass of grapefruit juice, a glass of water with naringin (which gives the bitter taste to grapefruit juice), or plain water.

Those who drank the grapefruit juice absorbed only half the amount of fexofenadine, compared to those who drank plain water.

Researchers said the water with naringin served to block “a key drug uptake transporter, called OATP1A2, involved in shuttling drugs from the small intestine to the bloodstream”.

Among the drugs affected by consumption of grapefruit, orange and apple juices are: etoposide, an anticancer agent; beta blockers used to treat high blood pressure and prevent heart attacks; and certain antibiotics (ciprofloxacin, levofloxacin, itraconazole).

The drug-lowering interaction also affected cyclosporine, a drug taken to prevent rejection of transplanted organs, and more drugs were expected to be added to the list as the research continued.
