摘要
目的 采用HPLC波长切换法同时测定通幽润燥丸中柚皮苷、新橙皮苷、黄芩苷、汉黄芩苷、黄芩素、汉黄芩素、和厚朴酚、厚朴酚和大黄酚9种活性成分的含量。方法 采用依利特Hypersil OSD2 C18色谱柱(250 mm×4.6 mm,5μm);以乙腈(A)-0.1%磷酸溶液(B)为流动相进行梯度洗脱;流速为1.0 mL?min–1;柱温为30℃;检测波长为275 m(柚皮苷、新橙皮苷、黄芩苷、汉黄芩苷、黄芩素、汉黄芩素)和220 m(和厚朴酚、厚朴酚、大黄酚);进样量10μL。结果 9种活性成分的分离度较好。柚皮苷、新橙皮苷、黄芩苷、汉黄芩苷、黄芩素、汉黄芩素、和厚朴酚、厚朴酚和大黄酚进样量分别在0.76~22.94,0.47~14.21,1.46~43.66,0.24~7.11,0.51~15.36,0.13~3.93,0.053~1.58,0.30~8.95,0.38~11.38 mg?mL–1内呈良好线性关系,平均加样回收率(n=6)分别为99.27%,100.04%,98.90%,100.10%,99.67%,98.75%,99.88%,99.59%,99.92%,RSD分别为0.12%,0.15%,0.41%,0.18%,0.28%,0.27%,0.65%,0.46%,0.24%。结论 通幽润燥丸中9种成分地含量测定方法准确,灵敏度高,分离效果好,能较好地评价该品种的质量,为该药物全面的质量控制提供了科学依据。
