    日期:2011.6
    on the bioactive screening results, three new pregnane glycosides named as cynanauriculoside C–E (1–3), were isolated from the roots of Cynanchum auriculatum Royle ex Wight (Asclepiadaceae), together with two known ones, otophylloside L (4) and cynauricuoside C (5). On the basis of detailed spectroscopic analysis and chemical method, the structures of new compounds were characterized to be qingyangshengenin

    Lyciumsterols A–K (1–11), 11 new octahydroxylated C21 steroids, were isolated from the root bark of Lycium chinense, along with 15 known compounds. Characterization of these C21 steroids showed the presence of eight hydroxy groups on the C21 steroid skeleton with a (2E,4E)-5-phenyl-2,4-pentadienoate group at C-12 or C-20 and various 2,6-deoxy sugar residues at C-3. The structures of these compounds
