[摘要]:Two new lanostane triterpenoids, schiglauzic acid (1) and schiglaucyclozic acid (2), together with two known ones, anwuweizic acid (3) and manwuweizic acid (4), were isolated from the stems of Schisandra glaucescens. Their structures were determined on the basis of extensive spectroscopic methods, including two-dimensional NMR techniques, and were further confirmed by X-ray crystallographic analysis. |
