摘　　要：该文建立了使用UPLC-QDA准确快速地测定培植牛黄中各胆汁酸类成分的方法,并通过该法对收集到的10批培植牛黄样品中的胆汁酸类成分的化学轮廓进行了全面考察与测定。结果在各批样品中可检测到的常见胆汁酸类成分共有9种,分别是胆酸、去氧胆酸、鹅去氧胆酸、牛磺胆酸、牛磺去氧胆酸、牛磺鹅去氧胆酸、甘氨胆酸、甘氨去氧胆酸和甘氨鹅去氧胆酸,其中除了甘氨去氧胆酸和甘氨鹅去氧胆酸外,其他7种胆汁酸类成分均可定量。测定结果显示,游离型胆汁酸是培植牛黄中主要的胆汁酸类成分,占其中胆汁酸类成分的97%以上,胆酸、去氧胆酸的含量最高,而胆酸的含量是去氧胆酸的近2倍。该研究建立的方法准确、快速、灵敏度高,设备相对价廉,适合用于相似样品的研究和测定。In this study, 10 batches of samples of cultured Bovis Calculus(cow-bezoar) were determined for the investigation of chemical profile of bile acids with the UPLC-QDA method established. The results showed that nine common bile acids, cholic acid(CA), deoxycholic acid(DCA), chenodeoxycholic acid(CDCA), taurocholic acid(TCA), taurodeoxycholic acid(TDCA), taurochenodeoxycholic acid(TCDCA), glycocholic acid(GCA), glycodeoxycholic acid(GDCA) and glycochenodeoxycholic acid(GCDCA), were founded in samples and 7 bile acids were quantified except GDCA and GCDCA. In these samples, unconjugated bile acids, the major type of bile acids, accounted for more than 97% of all types of bile acids. As for unconjugated bile acids, CA was the most major bile acid in cultured cow-bezoar and it was about twice as much as DCA. The relative low-cost method established in the current study is accurate, rapid and sensitive, which is suitable for the studies of other drugs from animal bile.
