This study was aimed to explore five Chinese medicine components or ingredients from Qu-Shi Hua-Y u Decoction (QSHYD) with uniform design method and screen ingredients assembling of Chinese medicine BZL pre-scription in order to verify its therapeutic effect on experimental fatty liver rats. High-fat diet was used in the estab-lishment of fatty liver rat models. Five effective ingredients (i.e., chlorogenic acid, geniposide, curcumin, polydatin and polysaccharide of Atractylodes macrocephala Koidz) of QSHYD were used as study subjects. Uniform design was applied in the grouping design. The intragastric administration was given for four weeks. The screening index was the content of liver triglyceride (TG). The ingredients assembling of Chinese medicine BZL prescription was screened through uniform design and regression analysis. The same fatty liver animal model was used in the comparison be-tween QSHYD and rosiglitazone. The TG content in liver tissues of rats and serum ALT activity were detected. The pathological changes of liver tissues were observed (HE stain and oil red O stain) with Ridit analysis to verify its therapeutic effect. The results showed that through screening, the regression equation was Y = 15.083X1 + 5.321X2- 5.186X3 - 16.157X4 + 9.35X5 + 17.667X3X4 - 8.422X1X2 - 6.617X3X5 + 16.571 (X1: chlorogenic acid, X2:polydatin, X3: polysaccharide of Atractylodes macrocephala Koidz, X4: geniposide, X5: curcumin). According to this equation, the best TG reducing effect occurred when the chlorogenic acid (X1), polysaccharide of Atractylodes macrocephala Koidz (X3), and geniposide (X4) were the maximum dosage. It showed that the best combination in inhibiting TG content in liver tissues was X3, X4 and X1 (i.e. BLZ prescription). Among fatty liver rat mod-els induced with same high-fat diet, the screened Chinese medicine ingredient BZL prescription can obviously reduce its TG content in liver tissues and serum ALT activity ( P < 0 . 01 ) . It obviously improved the fatty degen-eration of rat's liver. It was concluded that ingredients assembling of Chinese medicine BZL prescription screened through uniform design can obviously prevent and treat fat deposition and injury of the liver among rat models induced by high-fat diet .
