Abstract:
:Three new compounds, 15-acetoxy-12-hydroxy-16-methyl-labda-8(17),13E-diene (1), ent-labda-8(17),13-dien-15,16-olid-19-oic acid methyl ester (2), and 12-hydroxy-labda-8(17),13-dien-15,16-olide (3), together with two known compounds, 19-acetoxy-ent-labda-8(17),13-dien-15,16-olide (4), and 16-acetoxy-12,15-epoxy-15beta-hydroxy-labda-8(17),13(16)-diene (5) were isolated from the stem bark of Turraeanthus mannii (Meliaceae). The structures of compounds 1 - 3 were elucidated by analysis of the spectroscopic data. The crude methanol extract and compound 5 exhibited weak antibacterial and antifungal activity.
