Variety and distribution of Anhui native medicinal materials in ancient Chinese materia medica / 中国中药杂志

Anhui is located in the middle and lower reaches of the Yangtze River Plain, its across warm temperate zone and subtropics. The mountain and water next to each other, which leads to Chinese medicine resources ranked first in East China. The utilization of traditional Chinese medicine resources in Anhui has a long history, which could date back to the publishing time of Ming Yi Bie Lu (Appendant Records of Famous Physicians). And the kinds of traditional Chinese medicine in Song Dynasty ups to 80. There are also some differences in the distribution of various geographical units in terms of the types: Jianghuai hilly region's ups to 64, 25 in Wannan mountainous area, the species in Dabie Mountains and Huaibei plain are 16 and 14 respectively. In addition, the Jianghuai hilly region's and Wannan mountainous area have a long history among of them, which have been reached a peak in the Song Dynasty. The history of native medicinal materials in Anhui recorded in different periods, though combing herbal books. And the results showed that the vast majority of varieties in ancient are the same as modern ones, which provide the historical basis for the rich bulk medicinal materials in Anhui. The distinctions in natural and social environment of different geographical units have effects on the history of the usage of Chinese medicine resources in respective regions. Thus, the variety and distribution of native medicinal materials in Anhui among the Bencao works of different period provides herbalism basis for the protection and utilization of Chinese medicine resources currently.

Research and investigation on original plants of medicinal Moutan / 中国中药杂志

As a kind of famous ornamental flowers, Moutan, known as "the king of flower", mainly originates from various cultivars of Paeonia suffruticosa. Moutan Cortex, a common traditional Chinese medicine, has a long medicinal history for more than 2 000 years. At present, "Fengdanpi", which is the root bark of P. ostii mainly growing in Tongling, Anhui, is a sort of Dao-di herbs in traditional Chinese medicine. However,various editions of Chinese pharmacopoeia has been stipulating that Moutan Cortex originates from the bark root of P. suffruticosa. Textual researches on germplasm of ornamental and medicinal Moutan provided that, Xi'an, Luoyang, Pengcheng, Bozhou, Heze and some other famous cultivation centers had been formed throughout the history. In addition, medicinal practitioners in Song Dynasty had been fully aware of the medicinal differences between ornamental and wild Moutan, and preferred wild single flowers as medicinal Moutan. Moreover, none of cultivation centers of ornamental Moutan were recorded in producing areas of medicinal Moutan. So far, Fengdan and Dianjiang Moutan in Chongqing are single flowers, which is consistent with the ancient herbal books. Therefore, this paper believes that the medicinal and ornamental Moutan are two different germplasm since ancient times. And we proposethat Chinese pharmacopoeia should record P. ostii and the single-flower varieties of P. suffruticosa as the original plants of Moutan Cortex.

Anatomical structure and histochemical localization about rhizomes of five species of Polygonatum / 中国中药杂志

<p><b>OBJECTIVE</b>The microscopic structure and histochemical localization of the Polygonatum sibiricum, P. cytonema, P. filipes, P. zanlanscianense and P. odoratum was studied.</p><p><b>METHOD</b>Scanning electron microscope (SEM) and digital biological microscope (DBM) were applied in the research.</p><p><b>RESULT</b>Venation bundle showed in three types included collateral, amphivasal and incomplete amphivasal bundles. Morphological differences of venation bundles could be seen under the fluorescence microscope. Calcium oxalate existed in the mucilage cells looked similar to columnar crystals under SEM. In rhizome of Polygonatum, polysaccharides presented in mucilage cells, saponins and volatile oil were found in ground tissue.</p><p><b>CONCLUSION</b>Microstructure difference of rhizomes would be used for identification of the Polygonatum plants. Polysaccharides and saponins are distributed in different cells of Polygonatum plants.</p>

The change on worm situation, mildew degree, flower shape, color and appearance character were ovserved.</p><p><b>RESULT</b>The degree of worm and mildew situation of different regions of Chrysanthemi Flos was: Qiju < Hangju < Gongju < Chuju < Jiju = Huaiju = Damaya chrysanthemum. Among three cultivar species of Hangju, 'Huju' was the best preserved, following by 'Xiaobaiju', the worst was 'Dabaiju'. After the storage, the degree of worm situation of Gongju was different. The degree of worm situation of Chuju and Qiju were related to the process methods.</p><p><b>CONCLUSION</b>The storage changes of Chrysanthemi Flos were related to the regions, specise, process methods, geography location and harvest time, etc. Different specises of Chrysanthemi Flos had different storage time.</p>

<p><b>OBJECTIVE</b>To explore the differentiation mechanism of population biology between "Cangzhu" and "Baizhu", commonly used traditional Chinese drugs.</p><p><b>METHOD</b>The wild populations of Atractylodes in Anhui Province were investigated successively, in which specimens were studied, and the cultivated population was observed.</p><p><b>RESULT</b>The wild A. macrocephala and A. lancea, A. lancea subsp. luotianensis and A. lancea presented a series of successive transitions, which was caused by the change of ecological environment. A. macrocephala, A. lancea and A. lancea subsp. luotianensis were extreme types of the series of transitions, which were the germplasm of "Baizhu", "Cangzhu" and "Hancangzhu". The transitional types between A. macrocephala and A. lancea were similar of A. japonica, whose effect was the intermediate of "Baizhu" and "Cangzhu".</p><p><b>CONCLUSION</b>The development and differentatiation of commodites, the source of germplasm and the selection of geo-herbs of "Baizhu", "Cangzhu" and "Hancangzhu" are corresponding with the development of population biology of genus Atractylodes.</p>
