Abstract
目的::以制巴戟天中水晶兰苷含量为指标,优选制巴戟天炮制工艺。方法:以甘草用量、拌炒时间和煮制锅温为考察因素进行正交试验设计,采用HPLC法测定各样品中水晶兰苷含量:色谱柱为Kromalsil C18(200 mm ×4.6 mm,5μm);流动相为甲醇-0.4%磷酸水溶液(90∶10);柱温为30℃;流速为1 ml·min-1;检测波长为233 nm;进样量为5μl。结果:制巴戟天经不同工艺炮制后,各试验号水晶兰苷平均含量分别为0.5356,0.5824,0.5234,0.5891,0.5786,0.5878,0.5752,0.6091,0.5587 mg· g-1,说明制巴戟天炮制工艺的改变对水晶兰苷的含量有影响。结论:基于水晶兰苷含量的制巴戟天最佳炮制工艺为:甘草用量为6%,拌炒时间为10 min,煮制锅温为100℃。
