摘要

A novel lactone, tripterospermumcins E (1), along with four known compounds, sweroside (2), loganic acid (3), 8-epi-kingiside (4) and bergenin (5), were isolated from the aerial parts of Tripterospermum chinense. Their structures were determined by spectroscopic methods, including 1D and 2D NMR, and chemical methods. Compound 1 is rare beta-lactone with a glucoside.
