Abstract:Seven compounds have been isolated from the stems and leaves of Sibiraeaangustata (Rehd.) Hand-Mazz.. On the basis of spectral analyses (UV, IR, EI-MS, HNMR,13CNMR), the structures of these compounds were identified as betulinol (Ⅰ), ganodericacid Z(Ⅱ), ursolic acid (Ⅲ), 1-triacontanol (Ⅳ), tetracosanoic acid (Ⅴ), 10-nonacosanol(Ⅵ ) and 10-docosanol (Ⅶ ), respectively. The compounds Ⅰ, Ⅱ, Ⅳ, Ⅴ, Ⅵ, Ⅶ wereisolated from the plant for the first time.
