骆驼刺的化学成分研究

Studies on Chemical Constituents of Alhagi pseudalhagi(M.B.)

目的研究骆驼刺[Alhagi pseudalhagi（M.B.）]的化学成分。方法采用反复硅胶柱色谱法、SephadexLH-20柱色谱法等进行分离纯化,并通过化合物的理化性质和波谱数据进行结构鉴定。结果从骆驼刺体积分数70%乙醇提取物中分离得到10个化合物,其中4个异黄酮类化合物：芒柄花素（1）,3′,7-二羟基-4′-甲氧基异黄酮（2）,3′,7-二羟基-4′,8-二甲氧基异黄酮（3）,红车轴草素（4）;2个黄酮类化合物：柽柳素（5）,异槲皮苷（6）;2个酚酸类化合物：水杨酸（7）,香草酸（8）;β-谷甾醇（9）,胡萝卜苷（10）。结论化合物1~4,7,8均为首次从该属植物中分离得到。

OBJECTIVE To study the chemical constituents ofAlhagipseudalhagi （M.B.） . METHODS The compounds were isolated by chromatography on silica gel column, sephadex LH-20 column, and their structures were elucidated by spectral analysis. RESULTS Ten compounds were obtained and identified as formonoetin （ 1 ）, 3＇, 7-dihydroxyl-4＇- methoxylisoflavone（2）, 3＇, 7-dihydroxyl-4＇, 8-dimethoxylisofiavone（3）, pratensein （4）, tamarixetin （5）, isoquercitrin （6）, saliylic acid （7）, vanillic acid（8）, β-sitisterol（9） and daucosterol（10）, respectively. CONCLUSION Compound 1-4, 7 and 8 were isolated from this genus for the first time.
