The contents of ursodeoxycholic acid (UDCA) and chenodeoxycholic acid (CDCA) in Chinese medicinal compound preparations have been determined by TLC-densitometry. The determination wavelength was 375nm and reference wavelength was 700nm. For UDCA the linear range was 3.0-15.0 micrograms and recovery was 97.2% (RSD = 1.2%), and for CDCA the linear range was 4.0-20.0 micrograms and recovery was 99.3% (RSD = 2.1%).
采用薄层扫描法测定了中药复方制剂中熊去氧胆酸（UDCA）和鹅去氧胆酸（CDCA）的含量。测定波长为375nm，参比波长为700nm。熊去氧胆酸的线性范围为3.0 - 15.0微克，回收率为97.2%（相对标准偏差RSD = 1.2%）；鹅去氧胆酸的线性范围为4.0 - 20.0微克，回收率为99.3%（相对标准偏差RSD = 2.1%）。
