| Abstract: | Triterpenes,
stigmasterol, thwaitesii xanthone, apetalic acid, two new chromanones, decipic
acid and 12-acetyl apetalic acid are isolated for the first time from the ethyl
acetate extract of the bark of Calophyllum
decipiens, Guttiferae. Structures are elucidated by spectral studies. Apetalic
acid shows appreciable amount of radical scavenging activity on comparison with
trolox (standard) using DPPH free radical. It also shows antibacterial activity
against Mycobacterium tuberculosis H37Rv at 100 μg/mL using anti-TB drug
rifampicin at 0.5 μg/mL. |
