The effectiveness of position of the white peony is paeoniflorin, the effectiveness of position of the Schisandra is schizandrin, the effectiveness of position of the Danshen is Tanshinone ⅡA and salvianolic acid B, the effectiveness of position of the Pueraria is puerarin, the effectiveness of position of the licorice is liquiritin. In this thesis, both qualitative and quantitative analysis of the content of the raw herbs and finished effectiveness of position and detection methods. That the qualitative analysis of raw herbs and finished with thin layer chromatography , ultrasonic extraction to extract the finished product, quantitative analysis on raw herbs and finished by UV spectrophotometry. The results show that the original ingredients to meet the content standards set forth in the Pharmacopoeia of the People's Republic of China, that is, the original medicinal qualified. The determination of finished products: per 100g of paeoniflorin in 800mg,per 100g of puerarin in 800mg, per 100g of schizandrin in 300mg. Methodology investigated shows UV spectrophotometry in the determination of the original ingredients and finished content, the method is simple, reproducible, accurate and good stability.
