Objective:To develop an HPLC-ELSD method for the determination of verticine and verticinone in Wanbei Zhike capsule. Methods:The analysis was carried out on a Dikma C18 analytical column with the mobile phase consisting of acetonitrile-0.1% diethylamine (70∶30). The detector drift tube temperature was set at 93 ℃ and the nitrogen flow rate was 2.2 mL·min-1.Results:The recoveries for verticine and verticinone were 97.35% and 97.46% with RSD 1.24%and1.27%(n=5). Conclusion:The developed method is simple
rapid
replicable
and can be used for the quality control of the preparation.
