摘要
：A method for the quantitative determination of emodin in“Niuhuang Jiedu Pilulae” is developed by double wavelenth HPTLC densitometric scanning.Through sample scanning,stability investigation and recovery tests,it concludes that the suggested method is precise and accurate,and the results of determination reliable.
