[HPTLC densitometric determination of free bile acids in bezoar]
1National Institute for the Control of Pharmaceutical and Biological Products, Beijing.
Abstract:
Cholic acid (CA), chenodeoxycholic acid (CDCA) and deoxycholic acid (DCA) which are extracted with CH3OH from Bezoar can be separated on HPTLC silica gel plate (made in China) with isooctane-n-butyl acetate-acetic acid (4:2:1), and the three bile acids were determined by TLC densitometry.
