RESUMO
Objective To compare the difference of the results of the total flavones acquired by three kinds of quantitative an-alytical methods in the People's Republic of China Pharmacopoeia(method A),Health Food Function Components and Health Indica-tors Inspection Specifications(method B),and Health Food Inspection and Evaluation of Technical Specifications(method C)respec-tively. Methods Twenty-one drug and food homologies,medicines and other samples were detected by using the above mentioned methods respectively. Comparisons of the results were established. Results The measured values by method A were the highest,that of method C were the lowest. Moreover,the determination values of method A were higher than those by the methed B(1.4 ± 0.12) times,and the method C(2.1±0.31)times. Conclusion There are significant differences among the results of the total flavonoids de-terminated by the 3 methods in the same sample and the numerical relationship will be helpful for the quantity control of homologous food and drug.
