目的 研究薤白70%乙醇提取物的化學(xué)成分。方法 采用反復(fù)硅膠柱色譜、凝膠柱色譜法進(jìn)行分離純化，根據(jù)化合物的理化性質(zhì)和波譜數(shù)據(jù)鑒定化合物的結(jié)構(gòu)。結(jié)果 分離鑒定了6個(gè)化合物，分別為β-谷甾醇（1）、胡蘿卜苷（2）、胡蘿卜苷十一烷酸酯（3）、腺苷（4）、琥珀酸（5）、紫丁香苷（6）。結(jié)論 其中化合物3為首次從百合科植物中分離得到。

Objective To study the chemical constituents from 70% ethanol extract of Allii Macrostemonis Bulbus. Methods The compounds were isolated by repeated column chromatogram on silica gel and Sephadex LH-20. Physicochemical characteristics and spectroscopic evidences were employed for the structure identification. Results Six compounds were isolated and identified as β-sitosterol (1), daucosterol (2), sitosteryl-6′-O-undecane-β-D-glucoside (3), adenosine (4), succinic acid (5), and syringin (6). Conclusion Compound 3 is isolated from Liliaceae family for the first time.
