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.
从兴安升麻（Cimicifuga dahurica (Turcz.) MAXIM）地上部分分离得到了两种新的环羊毛甾烷醇木糖苷——升麻苷1和2，基于光谱数据和化学证据，确定它们的结构分别为(20R,24R)-24,25-环氧-3-β-(β-D-吡喃木糖氧基)-9,19-环羊毛甾-7-烯-16,23-二酮（1）和(20R,24R)-24,25-环氧-15-α-羟基-3-β-(β-D-吡喃木糖氧基)-9,19-环羊毛甾-7-烯-16,23-二酮（2）。
