摘要
建立高效液相色谱法测定雷公藤原料中雷公藤甲素的限度的方法,色谱柱为phenomenex C18;流动相为流动相A:甲醇,B:甲醇-水(40:60)梯度洗脱;流速为0.9mL·min^-1;检测波长218nm;柱温25℃,雷公藤甲素在0.0516-1.0320μg范围内呈良好的线性关系,r=0.9999,平均回收率99.3%,RSD为2.17%(n=6)。该方法操作简便,重现性好,结果准确可靠,适用于该原料的质量控制。
A HPLC method was established for the determination of triptolide in leigongteng. Usmg a phenomenex C18 column, a mixture of methanol -water (40 : 60) as the mobile phase, the detetive wavelenth was set at 218nm and the column temperature was 25℃. The linear range of Triptolide was from 0. 0516μg to 1. 0320μg (r=0. 9999). The average recoverage was 99.3% with RSD as 2.17% (n= 6). The method is simple, accurate and reliable, and can be used in the quality control of crude drug.
