Abstract
Three novel xylosides, cimicifugosides H-1(1), -3(2) and -4(3), were i
solated from a commercial Cimicifuga Rhizome. Their structures were de
termined on the basis of chemical and spectrometric evidence including
an X-ray crystallographic analysis. The xyloside 1 is 3-O-xyloside of
(20R,24R)-24,25-epoxy-3 beta,11 beta-dihydroxy-9,19-cyclolanost-7-ene
-16,23-dione, while 2 and 3 are 3-O-xylosides of 25,26,27-trinor-deriv
atives from the genin of 1.
