Wuyi is one of the Chinese medicine recorded in Shennong's Herbal Classic and many other herbal books during the long history period. Up to now, Wuyi is still an important medicine used for insecticidal and removing food retention. Recent researches indicated that Wuyi also had the function of anti-malaria and treating herpetic simplex keratitis. Therefore, Wuyi had notable value on clinic and development of new medicine. The herbalogical textual research on Wuyi was conducted through investigation of the literature of materia medica during the long historical period from Han Dynasty. It was demonstrated by this work that the original plants of Wuyi include Ulmus macrocarpa Hance and Hemiptelea davidii (Hance) Planch, in which, U. macrocarpa was the quality specie. U. pumila was the false specie which cause confusing. The medicine Wuyi was the processed product made from the nutlet of the plants through fermentation with other additive agents.

This article was aimed to study the therapeutic material basis of Xiong-Shao (XS) decoction on hepatic fi-brosis (HF), and screen effective parts from XS decoction for protecting liver, reducing enzyme activity and oxidative damage. Male wistar rats were randomly divided into the normal group, model group, Fu-Zheng Hua-Y u (FZHY) group, XS group, polysaccharide group, total alkaloids group and the total glycosides group. HF rat model was estab-lished with the intraperitoneal injection of DMN. After modeling, FZHY solution (0.105 g·mL-1), XS decoction (1.610 g·mL-1), crude polysaccharides extract of XS decoction (35.420 mg·mL-1), total glycosides extract solution (25.725 mg·mL-1), and total alkaloids extract of XS decoction (0.196 mg·mL-1) were administered to corresponding treatment group by gavage once a day for 4 weeks, respectively. Rats of the normal group and model group were given equiva-lent normal saline by gavage once a day for 4 weeks. After 4-week drug administration, rats were killed to remove the liver. Automatic biochemical analyzer was used in the detection of serum parameters of liver function, including ALT, AST, TIBL and ALB. Serum SOD activity was detected by xanthine oxidase. GSH-PX activity was tested by DTNB reduction. Serum contents of MDA were measured by TBA. Pathological changes of the liver were observed with HE staining and masson staining. The results showed that compared with the model group, there was no signifi-cant differences between the total alkaloids group and the model group, but levels of serum ALT, AST and TBIL of other treatment groups were significantly decreased, and the serum ALB level was significantly elevated (P< 0.05 or P < 0.01). Compared with the model group, levels of serum SOD and GSH-PX of the FZHY group, XS group and total alkaloids group were significantly elevated (P < 0.01), and level of serum MDA was significantly reduced (P <0.05 or P< 0.01). Comparison among the polysaccharides group, total glycosides group, and model group showed no significant differences. It was concluded that crude polysaccharide and total glycosides fractions were effective parts of XS decoction for protecting liver and reducing enzyme activity. And total alkaloids fraction was the effective part for reducing oxidative damage.
