Comparative Study Historical Article[Dissection of differences and similarities of botanical drugs in European Union, US and Canada].
Because of the unique nature and treatment concept of traditional Chinese medicines (TCMs), TCMs have been respected again since 70s of last century. The regulatory agencies of some developed countries (the FDA, EMA and Health Canada etc) have published new guidance/guidelines/directives in recent years, such as the botanical drug product guidance of the FDA, the evidence for quality of finished natural health products guidance of the Health Canada and the guideline on quality of herbal medicinal products/ traditional herbal medicinal products of the EMA etc. All of the regulatory agencies are willing to scientifically evaluate the herbal medicines and accept it as therapeutic product. This paper analyzed the history of herbal medicine regulation and the similarities and differences of the regulatory requirements of the European Union, the United States and Canada, proposed possible future direction of the international development of Chinese medicine from the perspective of global regulatory affairs.

[Correlation analysis soil nutrition as sell as yield and active compounds of Coptis teeta].
The correlations between soil nutrition and yield as well as active compound contents of Coptis teeta were analyzed. The contents of 13 soil factors, rhizome biomass and the content of berberine, jatrorrhizine, and palmatine in rhizome of C. teeta were determined, and analyzed by factor analysis (FA) and correlation analysis (CA). FA showed that the first three factors accounted for 86.9% of the total variance. ⋯ CA showed that yield of C. teeta had a significant positive correlation with available P (r = 0.931) at 0.01 level, and available N (r = 0.703) at 0.05 level. The content of berberine of C. teeta had a significant positive correlation with available P (r = 0.680) at 0.05 level. The yield and berberine content of C. teeta were high in the soil with high contents of available N and available P.

Comparative Study[Study and comparison on HPLC fingerprints of flavonoids of frequently used Chinese materia medica in citrus].
To establish the HPLC fingerprint of flavonoids of the six clinical frequently used Chinese materia medica for regulating Qi flow,such as Citri grandis, C. grands, Citri Reticulatae Pericarpium, Citri Reticulatae Pericarpium Viride, Aurantii Fructus, and Aurantii Fructus Immaturus from Citrus, and analysis differences in the fingerprints to provide scientific basis for profile-effect research and clinical reasonable use. ⋯ The established fingerprints of flavonoids of the six common traditional Chinese medicines can be used to compare the differences intuitively. Meanwhile, the peak height and peak areas of characteristic peaks are different remarkably, but whether it is connected with the different function of regulating Qi flow of the six medical materials in clinical use, is still needed to be studied.

[Speed up to formulate "National processing procedures of prepared slices of Chinese crude drugs", unified the national standards of prepared slices].
The prepared slices of Chinese crude drugs are growing important in recent years, and faced with new developments and opportunities. The author analyzed the importance of formulate national processing procedures of prepared slices of Chinese crude drugs combined actual work, proposed the overall objectives and tasks for the formulation, and emphasized to need to correctly deal with several important factors during the process of formulate "National processing procedures of prepared slices of Chinese crude drugs", unified the national standards of prepared slices, solved the real problems that the prepared slices of Chinese crude drugs industry faced.
