| Abstract: | Objective： to establish the assay method to detect the cholalic acid in bills bovina by HPLC to establish the base to institute drug standard of processing clruas adjuvant bills bovina. Methods： the 5C18 - PAQ Waters Collumn（4.6 mm×250 mm,5μm） was used and mobile phase was methanol-water-glacial acetic acid（72：28：0.2）. The flow rate was 1 ml/min. The evaporation photodetector flow rate of carrier gas was 2.2 L/min. The drift tube temperature was 85℃. Results： the cholalic acid had linear correlation during i. 648μg-- 4. 944 μg（ r = 0. 9998 ）. The average recovery was 99.48 % and the RSD was 4.2 %. Conclusion： this method is exact, convenient and good reproducibility and could use the assaying cholalic acid in bills hovina. |
