Four new 9,19-cyclolanostane-type triterpenes, 24-O-acetyl-25-anhydroshengmanol-3-O-beta-D-xylopyranoside (1), 25-O-butylcimigenol-3-O-beta-D-xylopyranoside (2), 12-beta-hydrocimigenol-3-one (3), and 12-beta-hydrocimigenol-1-en-3-one (4), together with 15 known analogues were isolated from the rhizome of Cimicifuga yunnanensis HSIAO. Their structures were determined by spectroscopic and chemical methods.
