[Studies on quantitative determination of total flavonoid in qingpi, zhiqiao and zhishi by TLC-densitometric methods].
A method for the determination of total flavonoid contents in Pericarpium Citri Reticulatae Viride (Qingpi), Fructus Aurantii (Zhiqiao) and Fructus Aurantii Immaturus (Zhishi) was established by the use of TLC-densitometry. The results show that the total flavonoid contents in Qingpi and Zhishi are higher than in Zhiqiao. The content in Zhiqiao is 9.81%-15.85%.
