Traditional application and modern research progress on new foreign medicinal resources / 中国中药杂志

Chinese medicinal resources are the material basis for the survival and development of traditional Chinese medicine(TCM)and the sustainable development of Chinese medicinal resources is also an important project for the modernization of TCM in China. With the increasing demand for Chinese medicinal resources in China, over-exploitation has destroyed Chinese medicinal resources, resulting in a shortage of many natural medicinal resources in China and making the sustainable development of TCM in trouble. The introduced new foreign medicinal resources have become effective supplement and replacement for Chinese medicinal resources to some extent. However, the development and utilization of new foreign medicinal resources in China are different. To fully understand the development of new foreign medicinal resources in China, this paper, taking 43 new foreign medicinal resources such as Acacia nilotica as objects, sorted out the introduction forms and policies of new foreign medicinal resources, overviewed its current development status in China, summarized the application experience of new foreign medicinal resources in the place of origin, as well as the research progress and problems of new foreign medicinal resources in China and abroad, and analyzed the research situation, which can enrich Chinese medicinal resources and other uses, promote the sustainable development of Chinese medicinal resources, and provide ideas for further development and research of new foreign medicinal resources.

Properties of new exotic traditional Chinese medicinal Vernonia amygdalina leaves:a literature research / 中国中药杂志

The leaves of Vernonia amygdalina Delile of the family Asteraceae(also known as "bitter leaf"), rich in biological activities, are used as both medicine and food for a long time in West tropical Africa. They have been introduced into Southeast Asia and Fujian and Guangdong provinces of China in recent years. However, little is known about the properties of the plant in traditional Chinese medicine(TCM), which limits its combination with other Chinese medicinal herbs. In this study, 473 articles on V. amygdalina leaves were selected from PubMed, Web of Science, CNKI, Wanfang Data and VIP to summarize their components, pharmacological effects and clinical research. V. amygdalina leaves presented anti-microbial, hypoglycemic, anti-hypertensive, lipid-lowering, anti-tumor, anti-inflammatory, antioxidant, and other pharmacological effects. On the basis of the theory of TCM properties, the leaves were inferred to be cold in property and bitter and sweet in flavor, acting on spleen, liver, stomach and large intestine and with the functions of clearing heat, drying dampness, purging fire, removing toxin, killing insects and preventing attack of malaria. They can be used to treat dampness-heat diarrhea, interior heat and diabetes, malaria, insect accumulation and eczema(5-10 g dry leaves by decoction per day and an appropriate amount of crushed fresh leaves applying to the affected area for external use). Due to the lack of TCM properties, V. amygdalina leaves are rarely used medicinally in China. The determination of medicinal properties of the leaves is conducive to the introduction of new exotic medicinal herbs and the development of new TCM resources, which facilitated further clinical application and research and development of Chinese medicinal herbs.

Application of tissue culture technology of medicinal plants in sustainable development of Chinese medicinal resources / 中国中药杂志

Chinese medicinal resources are the cornerstone of the sustainable development of traditional Chinese medicine industry. However, due to the fecundity of species, over-exploitation, and limitations of artificial cultivation, some medicinal plants are depleted and even endangered. Tissue culture, a breakthrough technology in the breeding of traditional Chinese medicinal materials, is not limited by time and space, and can allow the production on an annual basis, which plays an important role in the protection of Chinese medicinal resources. The present study reviewed the applications of tissue culture of medicinal plants in the field of Chinese medicinal resources, including rapid propagation of medicinal plant seedlings, breeding of novel high-yield and high-quality cultivars, construction of a genetic transformation system, and production of secondary metabolites. Meanwhile, the current challenges and suggestions for the future development of this field were also proposed.

Discussion on evolution of Mongolian medicinal material names and countermeasures for standardization / 中草药·英文版

Mongolian pharmacy is an important part of traditional medicine for the Chinese nation, with a long history and a complete theoretical system. The Mongolian people have accumulated and summarized the types and usage of Mongolian medicines in the practice of fighting against diseases over a long history. Mongolian medicinal resources are rich and diverse, the processing is self-contained, and the methods of medication are scientific and reasonable. Mongolian pharmacy not only has a deep historical relationship with traditional Chinese medicine but has also absorbed the essence of ancient Tibetan and Indian Ayurvedic medicine in the process of its development. We can identify the historical traces of the continuous exchange, communication, and integration of various ethnic medicinal cultures from the names of Mongolian medicinal materials. Because of the differences in languages and cultures of the various ethnic groups, the names of Mongolian medicinal materials have undergone a long historical period of evolution. These need to be further standardized owing to complications caused by the existence of synonyms and homonyms.

Textual Research on Illustrations of Medicinal Materials Named After Geographical Names of Jiangsu Province in Illustrated Classic of Materia Medica / 中国实验方剂学杂志

Illustrated Classic of Materia Medica （Ben Cao Tu Jing）， compiled in 1061， is regarded as the crystallization of the second national survey of Chinese medicinal resources in the history of China after the Newly Revised Materia Medica （Xin Xiu Ben Cao）， which serves as a precious source for exploring the Chinese medicinal resources in the Song Dynasty. The Illustrated Classic of Materia Medica （Ben Cao Tu Jing） covers 50 illustrations for Chinese medicinal materials named after geographical names of Jiangsu Province， 39 of which have been verified in today's Jiangsu Province. To be specific， Chinese medicinal materials in 32 illustrations can be traced back to their species， those in four illustrations to genera， and those in three illustrations to family. The remaining 12 illustrations remain to be further verified. The origins of most Chinese medicinal materials in the illustrations can be traced， which is attributed to their exquisiteness and lifelikeness as well as the detailed descriptions of the characters of the original plants and animals. In the textual research of these illustrations， we have noticed that there are inconsistencies between pictures and texts， and different illustrations may be derived from the same origin. This is believed to be related to SU Song's principle of collation that "for all Chinese medicinal materials presented as examples， if their shapes and categories recorded are not consistent with those in the literature， they will be retained. If there is any connection with the literature， they will be annotated according to literature to make their origins clear". As revealed by the distribution of Chinese medical materials in Jiangsu Province reported in the Illustrated Classic of Materia Medica （Ben Cao Tu Jing）， the utilization and development of Jiangsu medicinal materials during the Northern Song Dynasty were mainly concentrated in the low-altitude valleys and coastal areas. It could be seen from the illustrations of Chinese medicinal materials named after geographical names of today's Jiangsu Province that the production areas with a large number of illustrations were relatively developed in politics， economy， and transportation at that time， which enabled the medicinal resources to be fully utilized.

Research progress on medicinal resources of Coptis and its isoquinoline alkaloids / 中国中药杂志

Coptidis Rhizoma is a common Chinese medicinal in clinical practice,with the effects of clearing heat,drying dampness,purging fire,and removing toxin. All the medicinal plants of Coptis can be used for clinical treatment,but some species are endangered due to resource destruction and difficulty in planting. The dominant medicinal components in Coptidis Rhizoma are isoquinoline alkaloids. There are various methods for the analysis and detection of alkaloids,such as LC-MS,HPLC,and TLC,among which LC-MS is the most widely applied. Different plants of Coptis vary in the kind and content of alkaloids. C. chinensis,C. deltoidea,C. teeta,C. chinensis var. brevisepala,C. omeiensis,C. quinquefolia,and C. quinquesecta mainly contain berberine,palmatine,coptisine,jatrorrhizine,and columbamine,five effective alkaloid components. Plant isoquinoline alkaloids( PIAs) have strong pharmacological activity but are difficult to prepare. The application of synthetic biology of PIAs will be helpful for the clinical application of PIAs. This paper reviews the research progress on biological resources of Coptis species and structures of alkaloids as well as analysis methods and synthetic biology for isoquinoline alkaloids in the medicinal plants of Coptis in recent years,which will facilitate the protection of Coptis medicinal resources and the application and development of alkaloids.

Materia medica resources benefits Lancang-Mekong River:a new approach for sub-regional cooperation on traditional medicine / 中国中药杂志

Lancang-Mekong Cooperation is a new type of subregional cooperation mechanism initiated and built by China and other five countries of the Lancang-Mekong subregion, namely Laos, Myanmar, Thailand, Cambodia, and Vietnam. Countries in the Lancang-Mekong subregion are geographically and culturally connected, and they have nurtured their unique traditional medicine. By combing the history of traditional medicine exchanges between China and other Lancang-Mekong countries and their progress of modern research, this paper summarized the challenges and opportunities of traditional medicine cooperation in the Lancang-Mekong subregion. It has been found that many regional cooperation mechanisms coexist for a long time in the Lancang-Mekong subregion and the medicinal resources are abundant. However, the degree of their development and utilization varies, and modern scientific research is insufficient. Lancang-Mekong Cooperation has provided a strong support for integrating the advantageous resources in Lancang-Mekong subregion countries and making progress together. Focusing on the development and protection of medicinal resources, this paper puts forward a new path of cooperation in the intellectual property rights and characteristic seed resource protection, the compilation of universal herbal pharmacopoeia in various countries, the research and development of public health products, and the construction of traditional herbal industry bases, thus enabling the traditional medicine to better protect the public health and building a human health community.

Analysis of several key problems of good agricultural practice (GAP) of Chinese materia medica / 中国中药杂志

This paper reviewed the historical background of the GAP, analyzed the development experience of five Ps (GMP, GLP, GSP, GCP, GAP), analyzed the GAP based on economic theories, and pointed out that the core problem of GAP is ignoring economic laws. Once the GAP, is a process of certification, but neither the GAP announcement could be transformed into signal transmission quality in the product market, nor consumers could recognize the difference between GAP and non-GAP herbs in the terminal market, so manufacturers lack motivation for GAP certification. In this paper, we pointed out, that the GAP certification system should be redesigned under the guidance of economics, third party certification body, supervised by drug administration organization, to certificate GAP as high quality standards, to improve signal transduction mechanism of GAP certification, and to integrate GAP with the market.
