〔摘要〕 目的 观察黄芪-当归不同配比对毛蕊异黄酮苷、毛蕊异黄酮、芒柄花苷、芒柄花素、阿魏酸及洋川芎内酯I含量的影响。方法 采用水提法制备黄芪、当归及黄芪-当归不同配比(5∶1、1∶1、1∶5)的药液,通过高效液相色谱法对6种主要成分分别进行线性关系、精密度、重复性及回收率检测。结果 6种对照样品线性关系良好,仪器的精密度、样品的重复性及回收率均满足标准。黄芪-当归5∶1配伍时,6种成分的溶出量均未达90%;当配伍为1∶1和1∶5时,6种成分的溶出大多高于或接近100%。结论 黄芪-当归以1∶1和1∶5配伍时可促进两者主要成分的溶出,且1∶1配伍时溶出效果最好,说明在1∶1配伍时当归对有效成分的溶出有促进作用。

〔Abstract〕 Objective To observe the effects of different ratios of Huangqi (Astragali Radix)-Danggui (Angelicae Sinensis Radix) on the contents of calycosin-7-O-glucoside, calycosin, ononin, formononetin, ferulic acid and senkyunolide I. Methods The medicinal solutions of Huangqi (Astragali Radix), Danggui (Angelicae Sinensis Radix) and Huangqi (Astragali Radix)-Danggui (Angelicae Sinensis Radix) in different ratios (5∶1, 1∶1, 1∶5) were prepared by water extraction method, and the linear relationship, precision, repeatability and recovery rate of the 6 main components were tested by high performance liquid chromatography. Results The linear relationship of the 6 control samples was good, and the precision of the instrument, the repeatability of the sample and the recovery rate all met the standards. When the Huangqi (Astragali Radix)-Danggui (Angelicae Sinensis Radix) 5∶1 compatibility, the dissolution of the 6 components was lower than the 90%; when the compatibility was 1∶1 and 1∶5, the dissolution of the 6 components was mostly higher than or close to 100%. Conclusion Huangqi (Astragali Radix)-Danggui (Angelicae Sinensis Radix) can promote the dissolution of most ingredients in the medicine when the compatibility is 1∶1 and 1∶5, and the dissolution effect is the best when the compatibility is 1∶1, indicating that Danggui (Angelicae Sinensis Radix) can promote the dissolution of active ingredients in the 1∶1 compatibility.

药对是中医学精粹之一,是中医临床遣药组方常用的配伍形式,许多药对已成为经典名方。黄芪-当归配伍是常用的补气生血类药对,通常用于治疗血液系統、心脑血管系统及其肿瘤等疾病,在临床上应用频繁[1-4]。在中药复方中,名同实异的当归补血汤有很多,其中,使用最多的源自李东垣所创《内外伤辨惑论》,该方由黄芪5倍于当归配伍组成[5]。

已有研究表明,黄芪中的主要活性成分为黄酮、皂苷以及多糖[6]。当归中的主要成分为当归多糖、有机酸和挥发油等[7],在两者配伍中,黄芪中的黄芪甲苷、毛蕊异黄酮、芒柄花素和当归中的阿魏酸均有较高含量[8]。……
