目的 研究薤白70%乙醇提取物的化学成分。方法 采用反复硅胶柱色谱、凝胶柱色谱法进行分离纯化，根据化合物的理化性质和波谱数据鉴定化合物的结构。结果 分离鉴定了6个化合物，分别为β-谷甾醇（1）、胡萝卜苷（2）、胡萝卜苷十一烷酸酯（3）、腺苷（4）、琥珀酸（5）、紫丁香苷（6）。结论 其中化合物3为首次从百合科植物中分离得到。

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.
