摘要
Three new secoiridoids, swermacrolactones A-C (1-3), together with fourteen known compounds were isolated from Swertia macrosperma. Their structures were elucidated based on extensive spectroscopic analyses (IR, UV, MS, 1D and 2D NMR). By anti-HBV assay on the Hep G 2.2.15 cell line in vitro, the most active compound, luteolin (9), inhibited the secretion of hepatitis B virus surface antigen (HBsAg) and hepatitis B virus e antigen (HBeAg) with IC50 values of 0.02 and 0.02 mM, respectively.
