Keyword:  忍冬藤饮片显微鉴别薄层鉴别马钱苷反相高级液相色谱质量标准;
Abstract: 目的 制定忍冬藤饮片的质量控制方法.方法 采用显微鉴别、薄层色谱定性鉴别,采用高效液相色谱法测定饮片中的马钱苷.色谱条件:苯基硅烷键合硅胶色谱柱(4.6 mm×250 mm,5μm),流动相为乙腈-0.4%磷酸溶液(12:88),检测波长236 nm,流速1 mL·min-1,柱温40℃.结果 非腺毛、木纤维、皮层纤维、表皮细胞、草酸钙簇晶、木化薄壁细胞等显微特征明显,显微鉴别方法专属性强;薄层色谱斑点清晰,阴性对照无干扰.马钱苷的进样量在0.0868~1.3020μg范围内与峰面积积分值呈良好的线性关系,相关系数r=0.9999.平均回收率为99.96%,RSD=0.38%.测定山东、安徽、浙江等不同产地的19批样品,马钱苷含量以干燥品计算,结果在0.058%~0.863%区间分布.结论 本方法准确可靠、重现性好,可有效控制该饮片的质量.
