Abstract:
OBJECTIVE:To study the chemical constituents of Sedum lineare. METHODS:Silica gel column chromatogra-phy,TLC and crystallization were adopted to isolate the chemical constituents of S. lineare. And chemical structures were analyzed and identified based on physicochemical properties and spectral data of compounds. RESULTS:A total of 6 sterols and 2 triterpe-noids were isolated from petroleum ether fraction of S. lineare,which were identified as stigmaster-5-ene-3β-ol-7-one(1),stigmas-ter-5-ene-3β,7α-diol(2),daucosterol(3),daucosterol palmitate(4),β-sitosterol(5),stigmaster-7-ene-3β-ol(6),δ-amyrin(7),andδ-amyrone(8)respectively. CONCLUSIONS:Compounds 3,4 and 7 are isolated from S. lineare for the first time,and compound 4 is isolated from genus S.lineare for the first time. The study has laid certain foundation for the quality evaluation of S. lineare.
