【Abstract】 Objective: To establish two methods (HPLC UV and HPLC ELSD)for the determination of 3 kinds of cholic acids in Qingkailing Injection, and compare them with UV method. Methods: Two HPLC methods detected by UV and ELSD, respectively have been developed: Phenomenex Luna C 18 column(250mm×4.6mm,5μ)with linear gradient elution using methanol acetotrile(4∶1) and 0.1% aqueous formic acid. Results: Three kinds of cholic acids in Qingkailing could be determined simultaneously by HPLC UV and HPLC ELSD. The recovery of three method were 100%,97%,95%～96% for HPLC/ELSD,HPLC/UV,UV, respectively. Conclusion: The HPLC ELSD method was accurate and specific to determine the content of cholic acids in Qingkailing Injection.更多还原
