Varieties textual research on "Bangjian": traditional Tibetan medicine including blue, black and variegated flowers / 中国中药杂志

"Bangjian" were traditional Tibetan medicine-flowers from Gentianaceae, which were widely used and had a long medicinal history for the function of detoxifying, curing heat symptoms and treating the laryngitis. The Tibetan compound preparation endowed SFDA approval number always used Bangjian aas the main raw materials for relieving cough, asthma and treating respiratory diseases such as acute and chronic bronchitis. Its commodity medicinal materials were also sold in Qinghai, Sichuan, Tibet and other local medicinal materials market and local specialty marke. However, when recorded by literatures of Tibetan medicine, Bangjian were often classified into white, blue and black or white, blue and variegated according to color of flowers, leading to disordered varieties. In this paper, different Bangjian including their original plants and the main application varieties were studied and authenticated by textual research, wild specimen collection, investigation and collection of samples from Tibetan hospitals，Tibetan pharmaceutical factories and medical material markets. Results showed that Bangjian-including blue, black and variegated flowers were originated from 14 species and 3 varietas according to literatures, and the main application varieties mainly come from Ser. Ornatae of Sect. Monopodiae, such as Gentiana veitchiorum for the most, G. sino-ornata as well as G. lawrencei var. farreri. Suggestion about establishing the quality standard of Bangjian was gived, which provided reference in reasonable use and scientific research for Bangjian, and also had practical value for its clinical use and development.

Exploration on an overview of history (from Chunqiu to Ming and Qing Dynasties) and species of Chinese exotic traditional medicine / 中国中药杂志

This paper collected and analyzed literatures about starting of traditional medicine and trading of different medicine from Chunqiu Zhanguo to Ming and Qing Dynasties, in order to preliminarily explore on an overview of specie of chinese exotic traditional medicine and trade of different country in different dynasty（from Chunqiu to Ming and Qing Dynasties）, as well as the amount of exotic medicine over two thousand years. (remove repeating and doubtful species), find peculiarity of exotic medicine, sreen species that used to develop the Silk Route and establish quality standards.Finally, We get conclusions are as follows. First, primary,.prosperous and declining stages of development of exotic traditional medicine are Qin and Han, Song-Jin-Yuan, Ming and Qing Dynasties, respectively. Second, according to literature, the stage that has the most species of exotic medicine is song dynasty,approximately have 300. Removing repeating and doubtful species, the believable species are approximate 230 to 250. Meanwhile, the unknown species are approximate 30, which may be different name of one medicine or processed goods, now these medicines are named as "doubtful species". Third, the medicinal parts of exotic medicine are different from Chinese medicine of Han nation. The number of Resin, fruits and seeds kind are more than root and rhizomes kind,mineral medicines are more than animal.

Correspondence analysis between traditional commercial specifications and quantitative quality indices of Notopterygii Rhizoma et Radix / 中国中药杂志

This paper aims to explore a comprehensive assessment method combined traditional Chinese medicinal material specifications with quantitative quality indicators. Seventy-six samples of Notopterygii Rhizoma et Radix were collected on market and at producing areas. Traditional commercial specifications were described and assigned, and 10 chemical components and volatile oils were determined for each sample. Cluster analysis, Fisher discriminant analysis and correspondence analysis were used to establish the relationship between the traditional qualitative commercial specifications and quantitative chemical indices for comprehensive evaluating quality of medicinal materials, and quantitative classification of commercial grade and quality grade. A herb quality index (HQI) including traditional commercial specifications and chemical components for quantitative grade classification were established, and corresponding discriminant function were figured out for precise determination of quality grade and sub-grade of Notopterygii Rhizoma et Radix. The result showed that notopterol, isoimperatorin and volatile oil were the major components for determination of chemical quality, and their dividing values were specified for every grade and sub-grade of the commercial materials of Notopterygii Rhizoma et Radix. According to the result, essential relationship between traditional medicinal indicators, qualitative commercial specifications, and quantitative chemical composition indicators can be examined by K-mean cluster, Fisher discriminant analysis and correspondence analysis, which provide a new method for comprehensive quantitative evaluation of traditional Chinese medicine quality integrated traditional commodity specifications and quantitative modern chemical index.

Classics textual research and using situation investigation of Tibetan medicine "Zha-xun" / 中国中药杂志

In this article the classics textual research to the origin of "Zha-xun" was carried out, the ethnobotanical research methods, the origin of visits, key informant interviews, sample collection and textual research were applied in the research. The results showed that the hypothesis of Zha-xun"s origin mainly included "source of mine", "source of feces", "source of monkey menstrual blood" in China. There were "source of fossil", "source of the plant secretion" abroad. The authors had interviewed the villagers at origin, herbalists, Tibetan doctors, herb dealers, foreign scholars for a total of 18 people, and collecting 45 batches medicinal materials. According to ancient Tibetan classics textual and Tibetan medicine doctors' views, medicinal materials were divided into the genuine and the substitutes. The genuine was identified as ancient so-called "iron" type "Zha-xun", and the substitute was fecal pellet bonding briquette. According to the field survey and literature research, "source of fossil" more in line with substance of Zha-xun was derived from the rock. As the results, the author believed that Zha-xun was the mixture of organic fossils from the rock seepage with flying squirrel, pika feces. So it is needed to be set up Zha-xun classification standard to evaluate the quality of medicinal materials. Meanwhile, it was necessary to further clarify fecal pellet substitute rationality. Above all, this article clarified the status of the use of Tibetan medicine-"Zha-xun", and laid the foundation of species systematics and quality standards research of "Zha-xun".

Preliminary discussion on an overview of ethnic minority use of species of mineral medicine / 中国中药杂志

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.
