|
【西药炮制论文】【摘要】 目的测定滇黄芩不同炮制品中黄芩苷的含量。方法采用高效液相色谱法,色谱条件为:十八烷基硅烷键合硅胶为填充剂,甲醇0.2%磷酸(45∶55)为流动相,柱温为25℃,流速为1 ml·min-1,紫外检测波长为280 nm。结果滇黄芩不同炮制品中黄芩苷的含量差异很大,含量依次为生药5.98%,生片4.96%,酒片4.03%。结论该法简便易行,灵敏度高,重现性好,可用于滇黄芩药材及其制剂的质量控制。 【关键词】 滇黄芩; 黄芩苷; 高效液相色谱法 Abstract:ObjectiveTo establish an HPLC method for the determination of baicalin in the different prepared medical materials of Scutellaria amoena C.H. Wright. MethodsThe contents were determined by HPLC with the use of C18 column, and a mobile phase of methanol0.2% phosphoric acid (45∶55).The flow rate was 1.0 ml·min-1 and the detection wavelength was 280 nm.ResultsThe difference of baicalin contents in the different prepared medical materials of Scutellaria amoena C.H. Wright was obvious. The contents were in the decreasing order of raw Scutellaria (5.98%) > dried Scutellaria (4.96%) > prepared Scutellaria (4.03%). ConclusionThe method is si
