Resources Survey on Rare and Endangered Medicinal Plant Swertia mussotii Franch / 世界科学技术-中医药现代化

The resource of rare and endangered medicinal plant Swertia mussotii Franch. in Tibet, Qinghai and Sichuan province were surveyed by ways of documents, interview, quadrat and market investigation. The results indi-cated that Swertia mussotii Franch. mainly distributed in Zuogong and Mangkang of Tibet, Yushu of Qinghai province, Shiqu, Daofu, Kangding, Maerkang, Jinchuan and Xiaojin of Sichuan province. According to the height above sea level, the distribution altitude was from 2 300 m (Kangding of Sichuan province) to 3 900 m (Mangkang of Tibet). There are distributions of Swertia mussotii Franch. within the scope of 2 600 m. The illumination, water, soil, temperature and altitude had significant influence on the distribution, growth and reserve of Swertia mussotii Franch. from different angles. In recent years, there was huge increase of market requirement in Swertia mussotii Franch. which were used in Tibetan medicine Zangyinc he n. Excess collection was the primary cause of rapid decreasing in resource of Swertia mussotii Franch.. It was suggested to strengthen the management of rational collection, as well as to accelerate the development of cultivation and production.

Determination of podophyllotoxin and total lignans in Sinopodophyllum emodi / 中国中药杂志

<p><b>OBJECTIVE</b>To determine the content of podophyllotoxin and total lignans in Sinopodophyllum emodi Ying from different areas and evaluate the resource utilization of this endangered medicinal plant.</p><p><b>METHOD</b>HPLC and UV spectrophotometry were used to determine the content of podophyllotoxin and total lignans in 126 samples from different habitats and the total lignans content was determined by the reference wavelength method.</p><p><b>RESULT</b>According to the results, the highest content was determined from the samples from Yongdeng Nature Reserve in Gansu province, and the lowest ones was found in the samples from Tibet. The former's podophyllotoxin and total lignans contents were 7.40% and 20.66%, respectively, which were 19 times and 4 times more than those of the latter. The content of podophyllotoxin and total lignans in S. emodi were significantly positively related, meanwhile, samples from both low altitude and high latitude showed the higher content.</p><p><b>CONCLUSION</b>The two determination methods are simple, rapid, accurate and repeatable. It is more scientific and rational to evaluate the resource utilization of S. emodi with two indicators, those are the content of podophyllotoxin and the content of total lignans. This paper is instructive to the collection of wild resources and the establishment of production bases.</p>

Difference of chemical constituents contained in Tibetan herb Jiadiranguo from different habitats by HPLC fingerprint / 中国中药杂志

<p><b>OBJECTIVE</b>To establish the HPLC fingerprint for Halenia elliptica herbs, a traditional Tibetan medicine, in order to study constituents contained in H. elliptica from different habitats and compare their differences.</p><p><b>METHOD</b>HPLC analysis was made on a Welchrom-C18 (4.6 mm x 250 mm, 5 microm) with water and acetonitrile as mobile phase. The wavelength was detected as 265 nm, the flow rate was 1.0 mL x min(-1), and the column temperature was 40 degrees C. The software for chromatographic fingerprint was applied to analyze the similarity. And principal component analysis was conducted.</p><p><b>RESULT</b>Twelve common chromatographic peaks were identified by fingerprint, showing a low similarity in constituent and variety. The significant difference in the proportion between xanthones and aglycones in each batch of herbs indicated no notable correlation between constituent characteristics and geographic locations of habitats.</p><p><b>CONCLUSION</b>The method is so simple, exclusive, stable and highly repeatable that it can provide reference for identification and quality assessment of H. elliptica herbs.</p>

Resources of survey in rare and endangered medicinal plant Sinopodophyllum emodi / 中国中药杂志

The resource of Sinopodophyllum emodi in Tibet, Qinghai, Gansu, Sichuan and Yunnan province were surveyed by the ways of documents, interview, quadrat and market investigation. The results indicated that S. emodi were mainly distributed in central part from Taibai Shan of Shanxi province along the middle and high mountain on either side of Hengduan mountain which from north to south and in Tibetan plateau of China, the suitable eco-environment of S. emodi was dominated by valleys, wet forests and low bush-woods vegetation which comparatively dry on plateau with the altitude focused on 1 5004 500 meters, and the distribution density of simple alpine meadow was relatively lower. Illumination, water, soil, temperature and altitude had significant influences on the growth, distribution and reserves of S. emodi from different angles. In recent years, there was sharp increase of market requirement in Xiaoyelian (fruit) which were used in Tibetan medicine and the underground part which was used for the extraction of podophyllotoxin, excess collection of the underground part was the primary cause of the rapid decreasing resource of S. emodi. It is suggested that the management of rational collection should be strengthen and the development of culturing and production should be meanwhile accelerated.

Determination of xanthones in Tibetan herb Jiadiranguo (Herba Haleniae) / 中国中药杂志

A HPLC method was developed for simultaneous determination of 1-hydroxy-2, 3, 4, 7-trimethoxyxanthone (1), 1-hydroxy-2,3, 7- trimethoxyxanthone (2), 1-hydroxy-2, 3, 4, 5-trimethoxyxanthone (3), and 1-hydroxy-2, 3, 5- trimethoxyxanthone (4) in Halenia elliptica. The analytical column was Welchrom C18 column (4.6 mm x 250 mm, 5 microm). The mobile phase was acetonitrile- water (43:57). The detection wavelength was 265 nm. The flow rate was 1 mL x min(-1) and the column temperature was set at 40 degrees C. There was good linearity between the peak areas and concentration at the ranges of 0.414-16.6, 1.73-69.6, 5.89-117, 3.01-120.5 mg x L(-1) for 1, 2, 3 and 4 respectively. The average recoveries (n = 6) of 1, 2, 3 and 4 were 102.5%, 100.5%, 97.9% and 101.2%. Those four xanthones in thirty samples of H. elliptica. were determined by this method. The method is simple, accurate, repeatable, which could be used for the quality evaluation of H. elliptica. The total content of those four xanthones in H. elliptica should not less than 1.80% by comprehensive analysis.

Textual criticized and collated on names and breeds of Tibetan medicine "Dida" / 中国中药杂志

Integrating textual criticism literatures with field survey, the name, classification and botanical originals of breeds of Tibetan medicine "Dida" were discussed in this paper. The results showed that it's very intricate and confusion in the names, breeds and botanical originals of "Dida", and those were the key restricting factors resulting in shortfall and difficult formulation in quality standard of "Dida". The similar situations are existing universally in ethnodrugs, and reflecting the necessity and urgency to collate ethnodrug breeds. On the other hand, Because of the morphologic description on the botanical origins of drug was often simple in the ancient literatures, and in most cases, the botanical origins of the drug were difficult to identify accurately on the basis of the literatures. So, in the collating the breeds, it's necessary to follow the principle of "according to the ancient literatures but no rigidly", and to pay attention to the historical vicissitude of the drug breeds and origins, and the survey of present resources and clinical using, draw actively on outcome of chemical and biological active researches. That inherited the characteristics and advantages of ethnodrugs, and promoted them them modernization.
