Cimidahuside 1 and 2, two new cyclolanostanol xylosides from the aerial parts of Cimicifuga dahurica.
Cimidahuside 1 and 2, two new cyclolanostanol xylosides were isolated from the aerial parts of Cimicifuga dahurica (Turcz.) MAXIM, on the basis of spectral data and chemical evidences, their structures were determined to be (20R,24R)-24,25-epoxy-3-beta-(beta-D-xylopyranosyloxy)-9,19-cyclolanost-7-ene-16,23-dione (1), and (20R,24R)-24,25-epxy-15-alpha-hydroxy-3-beta-((bet-D-xylpyranosyoxy)-9,19-cyclanost-7-ene-16,23-dione (2), respectively.
