Simultaneous determination of 15 bile acids in Tongren niuhuang qingxin pills by UPLC-MS/MS
To establish a method for simultaneous determination of 15 bile acids in Tongren niuhuang qingxin pills, and to determine the contents of 15 batches of samples.
METHODS
2
Using dehydrocholic acid as internal standard, the determination was performed by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method. The determination was performed on Hypersil GOLD C
18
column with methanol-0.1% formic acid solution as the mobile phase by gradient elution at the flow rate of 0.2 mL/min. The column temperature was 40 ℃, and the sample size was 2 µL. Using heated electrospray ion source, parallel reaction monitoring mode scanning was performed in negative ion mode. SPSS 24.0 software was used for chemical pattern recognition analysis of content determination results.
RESULTS
2
The 15 bile acid components had a good linear relationship with peak area (all

-cholanic acid, hyocholic acid, taurodeoxycholic acid sodium salt hydrate, hyodeoxycholic acid, cholic acid, glycochenodeoxycholic acid, glycodeoxycholic acid, chenodeoxycholic acid and deoxycholic acid were 670.56, 25.97, 10.54, 280.12, 4.04, 29.81, 182.98, 813.55, 120.95, 220.31, 797.37, 18.37, 68.59, 30.13, 59.82 μg/g, respectively. Both cluster analysis and principal component analysis divided 15 batches of Tongren niuhuang qingxin pills into 2 categories, S1-S12 as one category and S13-S15 as the other category.
CONCLUSIONS
2
The established method is accurate, sensitive and specific, and can determine many types of bile acids. It also can quickly achieve the quantitative analysis of 15 bile acids in Tongren niuhuang qingxin pills, which is suitable for the quality control of this drug.
