窄叶鲜卑花的化学成分研究

STUDIES ON THE CHEMICAL CONSTITUENTS OF SIBIRAEA ANGUSTATA

摘要:

从窄叶鲜卑花（Sibiraeaangustata（Rehd．）Hand-Mazz．）枝叶中分离得到7个结晶，经解析各种光谱数据，分别鉴定为：白桦脂醇（betulinol）（Ⅰ）、灵芝酸Z（ganoderiacidZ）（Ⅱ）、熊果酸（ursolicacid）（Ⅲ）、正三十烷醇（n－triacontanol）（Ⅳ）、正二十四烷酸（n-tetracosanoicacid）（Ⅴ）、二十九烷醇-10（10－nonacosanol）（Ⅵ）、二十二烷醇-10（10-docosanol（Ⅶ）.除熊果酸（Ⅲ）外，其它6个化合物均系首次从该植物中获得。

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.
