On the basis of literatures and standards relating to Tibetan medicine, the varieties, origin, standards and efficacy of Saxifragaceae plant used in Tibetan medicine were summarized. According to the findings, 75 species(including varieties) in 8 genera of Saxifragaceae plants, involving 21 varieties, are used in Tibetan medicine. Among them, 9 commonly used varieties, namely Songdi, Sedi, Yajima, Aoledansaierbao, Jiansidawu, Saiguo, Katuer, Sangdi, Maoqinghong, are recorded in Chinese Pharmacopoeia, Ministry Standards for Tibetan Medicine, Tibetan Medicine Standards and other local standards, accounting for 42.9% of the total number of varieties. Tibetan names, Tibetan translation of Chinese names, as well as original plant of Tibetan medicine varieties are quite different in relevant Tibetan medicine standards and literatures, which resulted in common phenomena of synonym and homonym. The standards of most varieties only involve characters, and microscopic, physical and chemical identification, with low quality standards. Based on the results of the analysis, this paper suggests strengthening surveys on herbal textual research, resources and current utilization of Saxifragaceae plants used in Tibetan medicine, summarizing the varieties, establishing improved quality standards, and perfor-ming a comparative study on therapeutic material basis and biological activity of different original plants, in order to promote rational use of these medicinal plant resources, and ensuring the accuracy, safety, and effectiveness of clinical medication.

Zingiber officinale has a long application history in China, it is used as medicine, also condiment, food and drinks. The chemical constituents of Zingiber officinale include volatile oil, gingerol, diaryl-heptnaoids and so on. Scientific research showed that Zingiber officinale is widely used in anti-nausea, resisting gastric ulcer, anti-bacterial, anti-phlogistic, analgesia, antioxidant, resisting motion sickness, anti-tumor, hypoglycemic, antilipidemic, and improving cardiocerebral vascular system and so on. Zingiber officinale is recommended as a healthy food by doctor of traditional Chinese medicine in all times. In summary, it's worth to be researched and developed in detail.

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

With the kernel of efficacy, "Xiaohe Silian" was a pattern and method for new drug discovery which was constituted with "metabolism-efficacy, toxicity-efficacy, quality-efficacy and structure-efficacy". Its connotation was in keeping with traditional Chinese medicine (TCM) clinical pharmacy. This paper systematically summarized the research method of new drug discovery practice process for TCM. To avoid western drug like in TCM new drug discovery, we carried out combination analysis with TCM clinical pharmacy. The correlation analysis between basic elements of "Xiaohe Silian(n) and TCM clinical pharmacy was studied to guarantee this method could integrate closely with TCM clinic from all angles. Hence, this method aimed to provide a new method for TCM new drug discovery on the basis of TCM clinical pharmacy with insisting on holistic view of multicomponent study, kinetic view of metabolic process when the curative effect occurred and molecular material view of quality control and structure-activity exposition.

Multicomponent drug metabolism can be defined as a research area that, rather than pharmacokinetics and pharmacodynamics, is a concerted dynamic metabolic variation of one component in several other compounds circumstance with the interaction of transport protein and drug metabolizing enzymes, and the study of the dynamic course of multiple components must be simultaneously determined. By the use of multicomponent drug metabolism in the clinical pharmacy research of traditional Chinese medicine (TCM), it can become a useful tool with the integration of the overall dialectical method and the concrete molecular approach.
