Determination and difference analysis of bile acid active constituents of artificial bezoar in Babao jingfeng powder from different manufacturers
To establish the method for determination of bile acid active constituents (cholic acid, hyodeoxycholic acid and sodium taurocholate) in Babao jingfeng powder, and to compare the differences of 3 constituents in Babao jingfeng powder from different manufacturers.
METHODS
2
UPLC-MS method was adopted to determine the contents of cholic acid, hyodeoxycholic acid and sodium taurocholate in 9 batches of Babao jingfeng powder from 3 manufacturers. The separation was performed on a Phenomenex Luna

column with mobile phase consisted of acetonitrile-water (gradient elution) at a flow rate of 0.5 mL/min. The column temperature was 40 ℃ and the sample size was 2 μL. MS system was operated in a negative ion single quadrupole mode, and the

of cholic acid, hyodeoxycholic acid and sodium taurocholate were 407.2, 392.2 and 514.2, respectively. With the contents of three components as the index, cluster analysis and principle component analysis were performed on 9 batches of samples.
RESULTS
2
The linear ranges of cholic acid, hyodeoxycholic acid and sodium taurocholate were 5.48-548.40, 5.38-538.40, 4.74-474.05 ng/mL, respectively (
r
≥0.999 3). RSDs of precision, repeatability and stability tests (24 h) were all lower than or equal to 3.7% (
n
=6), and the average recoveries were 103.3%, 103.3% and 101.6% with RSDs of 3.3%, 3.4%, 4.2% (
n
=6), respectively. The contents of cholic acid ranged 0.702-1.711 mg/g, those of deoxycholic acid ranged 0.599-2.049 mg/g, and those of sodium taurocholate ranged 0.664-1.752 mg/g in 9 batches of samples. The average content of 3 components in samples from manufacturer A was high, and the difference between batches was the smallest; the average content of 3 components from manufacturer C was the lowest, and the difference between batches was large. Cluster analysis could basically distinguish samples from different manufacturers; cluster analysis was conducted by using the comprehensive score of principal components as an indicator, the results of which were basically consistent with those of cluster analysis for content.
CONCLUSIONS
2
The method is established successfully for the content determination of the 3 bile acid active constituents of artificial bezoar in Babao jingfeng powder. The contents of 3 components in Babao jingfeng powder from 3 manufacturers are significantly different.
