高效液相色谱法测定蟾酥中有效成分的含量

目的:建立HPLC法测定蟾酥药材中有效成分的含量。方法:选用0.5%磷酸二氢钾溶液乙腈(50:50)(磷酸调节pH为3.25±0.02)为流动相测定蟾酥药材中华蟾酥毒基和脂蟾毒配基的含量。结果:测定组分具有良好的线性关系和分离度,华蟾酥毒基的平均回收率为100.35%,RSD=1.86%,脂蟾毒配基的平均回收率为100.38%,RSD=2.09%。结论:本方法简便、快速、准确,具有实用性

Determination of Resibufogenin and Cinobufagin in Venenum Bufonis by HPLC

OBJECTIVE: To establish a HPLC method to determine the contents of active constituents in Venenum Bufonis. METHOD: In determining the contents of resibufogenin and cinobufagin in the traditional Chinese medicine Venenum Bufonis, the mobile phase was acetonitrile-0.5% KH2PO4 solution(50:50)(pH adjusted with value phosphoric acid to 3.25 +/- 0.02). RESULT: The constituents thus determined have good linearity and separation. The average recovery of resibufogenin was 100.35%, RSD 1.86%; the average recovery of cinobufagin was 100.38%, RSD 2.09%. CONCLUSION: The method was convenient, rapid, accurate and practicable.
