Sesquiterpenes from the fruits of Illicium Simonsii maxim.

A new allo-cedrane sesquiterpene glycoside (1) and nine known compounds (2-10) were isolated from the ethanol extract of the fruit of Illicium simonii Maxim. Their structures were elucidated by spectroscopic methods, including 1D-, 2D-NMR, and HRESIMS. The absolute configuration of compound 1 was confirmed by CD experiments. Among them, compounds 1, 4, 5, and 7 displayed moderate anti-inflammatory activities by use of an in vitro bioassay.
