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 <i style="">Calophyllum decipiens</i>, 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 <i>Mycobacterium tuberculosis</i> H37Rv at 100 μg/mL using anti-TB drug rifampicin at 0.5 μg/mL.
