摘要:Three New Cyclolanostanol Xylosides Were Isolated From A Batch Of Commercial Cimicifuga Rhizome,Cimicifugoside H-1 (1),C35H52O9,Mp 260-262°C,[α]D-43.5°,Cimicifugoside H-2 (2),C35H54O10,Mp 227-229°C,[α]D-38.8°,And Cimicifugoside H-5 (3),C35H52O10,Mp 262-264°C,[α]D-22.9°,Together With Known Glycosides,Actein And 27-Deoxyactein. Their Structures Were Determined On The Basis Of Chemical And Spectrometric Evidence Including An X-Ray Crystallographic Analysis. The Structure Of Cimicifugoside H-1 (1) Was Established As (20R,24R)-24,25-Epoxy-11β-Hydroxy-3-β-(β-D-Xylopyranosyloxy)-9,19-Cyclolanost-7-Ene-16,23-Dione. Cimicifugoside H-5 (3) Is The 15-Hydroxylated Derivative Of 1. Since 1 Changed Into Cimicifugoside H-2 (2) On Treatment With P-Toluenesulfonic Acid,2 Has A 24R,25-Diol Structure Derived From 1 By Opening Its Epoxy Ring.
