Abstract
Three new eudesmanolide sesquiterpenes, neolitacumone A−C (1−3), and one new benzylisoquinoline alkaloid, neolitacumonine (5), along with 27 known compounds were isolated from the stem bark of Neolitsea acuminatissima. The structures of compounds 1−3 and 5 were established on the basis of spectral and chemical evidence. Compounds 2, 3, and 20 were selectively inhibitory to Hep 2,2,15 cells with IC50 values in the range 0.24−0.04 μg/mL. Compound 20 was marginally cytotoxic to Hep G2 cells.Keywords
