• Study yielded an azaanthracene alkaloid, kalasinamide, from the stems of P. suberosa., together with the known N-trans-feruloyltyramine and N-trans-coumaroyltyramine.
• Study isolated two new 2-substituted furans from the stems of P. suberosa.
• Leaves contain alpha- and beta-amyrin, lupeol, beta-sitosterol, stigmasterol and campesterol. Stems and leaves contain triterpene, suberosol, which have shown anti-HIV replication activity. Stem bark yields alkaloids, oxostephanine and lanuginosine, which has shown antibacterial activity.
• Anti-HIV replication activity and antibacterial activity.
Parts used : Fresh roots
Decoction of fresh roots used as abortifacient.
• Furans / Antiviral Activity: 2-substituted furans from Polyalthia suberosa: Two new 2-substituted furans, 1-(2-furyl)pentacosa16,18-diyne and 23-(2-furyl)tricosa-5,7-diynoic acid, were isolated from the stems of P. suberosa. These compounds, with kalasinamide, N-trans-feruloyltyramine and N-trans-coumaroyltyramine showed anti-HIV activities.
• Anti-HIV Activity: Anti-AIDS Agents, 9. Suberosol, a New C31 Lanostane-Type Triterpene and Anti-HIV Principle from Polyalthia suberosa: In the course of searching for anti-HIV agents, a new triterpene, suberosol, was isolated and studied for anti-HIV activity. (Publ.1993)
• Cytotoxic: Study isolated four new styryl-lactones, crassalactones A-D together with seven known compounds from an extract of leaves and twigs of PC. Cytotoxic evaluation against mammalian cancer lines were done on all the new isolates.
