摘要：

Four new furostanol saponins, named aspidsaponins E-H (1-4) were isolated from the rhizomes of Aspidistra elatior Blume. Their structures were determined based on chemical methods and spectral data. Compounds 1 and 2 were a pair of diastereoisomeric furostanol saponins and possessed the highly oxidized structural feature of 1 beta, 2 beta, 3 beta, 4 beta, 5 beta, 26-hexanol-steroids, and compounds 3-4 were steroidal glycosides with a tetra-saccharide chain at C3. The isolated compounds (1-4) were tested in vitro for inhibitory activities against LPS-induced nitric oxide production in RAW264.7 macrophages. Among them, compounds 3 and 4 showed excellent anti-inflammatory activities with IC50 values 82.1 and 65.9 mu M, respectively.
