Objective: To establish the content determination method for cholic acid in Yansukang by HPLC-ELSD. Method: An HPLC method was applied with Kromasil-C18 column (4.6 mm×250mm
5 μm) by a gradient elution using A (methanol)-B (0.1% glacial acetic acid solution) as the mobile phase.The drift tube temperature was set at 75 ℃
and N2 pressure was 33 psi. Result: The linear range of cholic acid was 0.6542-16.355 μg;The correlation coefficient (r) was 0.999 8
and the average recovery was 100.27%
with RSD 2.13% ( n =6). Conclusion: The method is accurate and reproducible
and can be used to determine the content of cholic acid in Yansukang.
