目的 研究生藤的化學(xué)成分。方法 利用各種色譜技術(shù)分離純化,通過理化常數(shù)測定和波譜方法鑒定其結(jié)構(gòu)。結(jié)果 從生藤莖的95%Et OH 提取物中分離得到7個(gè)化合物,其結(jié)構(gòu)經(jīng)波譜等方法鑒定為β-谷甾醇-3-O-β-D-葡萄糖苷-6′-O-二十烷酸酯(Ⅰ),2α,3β,23-三羥基-齊墩果-12-烯-28-酸(Ⅱ),2α,3β,23-三羥基-烏蘇-12-烯-28-酸(Ⅲ),β-谷甾醇-3-O-β-D-葡萄糖苷(Ⅳ),硬脂酸(Ⅳ),葡萄糖(Ⅵ)和蔗糖(Ⅶ)。結(jié)論 所有化合物均為首次從該植物中分離得到,其中化合物Ⅰ為1新化合物。

Object To study the chemical constituents of Stelmatocrypton khasianum (Benth.) H. Baill.. Methods Some constituents were isolated by chromatographic methods and identified by physicochemical constants and their structures were elucidated by spectral data. Results Seven compounds were isolated from the stem of S. khasianum and their structures were identified as β-sitosterol-3-O-β-D-glucoside-6′-O-eicosanate (Ⅰ), 2α, 3β, 23-trihydroxy-olean-12-ene-28-oic acid (Ⅱ), 2α, 3β, 23-trihydroxy-urs-12-ene-28-oic acid (Ⅲ), β-sitosterol-3-O-β-D-glucoside (Ⅳ), stearic acid (Ⅴ), glucose (Ⅵ), and sucrose (Ⅶ) respectively. Conclusion All compounds were obtained from this plant for the first time, and compound I is new.
