Wenxiu, an associate professor, introduced the identification of precious medicinal materials / Hu Jiaqi, a reporter from our newspaper, took pictures of rare and precious medicinal materials such as Cordyceps sinensis and crocus, which were rare in supply and expensive in price, and there were many cases of forgery and confusion In order to establish a set of standardized and popular identification methods for traditional Chinese medicine, many experts from University of science and Technology launched a study on "identification of precious medicinal materials" for 30 kinds of commonly used medicinal materials five years ago, and published the results into a book recently The book is expected to provide reference standards for the public and the industry and promote the modernization of traditional Chinese medicine Li Da has been engaged in the research of traditional Chinese medicine in Nanshan District Laboratory of Shenzhen since the beginning of 2001, and was approved by the Ministry of science and technology of the people's Republic of China and Shenzhen municipal government to establish "Shenzhen Key Laboratory of traditional Chinese medicine pharmacy and Molecular Pharmacology" In 2008, the laboratory carried out the research on the identification of rare medicinal materials The team led by Yang Dajian, President of Chongqing Institute of traditional Chinese medicine, Chen Xinzi, former vice president of Li and current president of Baptist University aims to establish a set of practical identification methods of rare medicinal materials, so as to improve the professional level of the industry and the public's understanding of famous medicinal materials The team completed the research work earlier, and compiled the results into a book named "identification of precious medicinal materials", showing different precious medicinal materials and their common confusions and fake products with pictures and texts, and collecting a variety of methods for identification of authenticity Collect samples of different origins and grades The team selected 30 kinds of commonly used and precious medicinal materials with large circulation, high cost and easy to be confused, such as ginseng, Panax notoginseng, Fritillaria sichuanensis, snow lotus, Cordyceps sinensis, etc as the research objects, and collected samples from different places of origin and grades, as well as a variety of confused, adulterated and fake products in multiple distribution centers of traditional Chinese medicine in China, analyzed the appearance and properties of different samples, and used microscope and chemical technology Learn technology and other methods to identify So far, the team has collected thousands of samples of traditional Chinese medicine and made more than 60 display specimens Mo Jinhua, an assistant professor in the Department of Applied Biology and chemical science and technology at the University of science and technology, who participated in the research, said that the team found effective methods to identify different traditional Chinese medicines during the research For example, as long as we master the cross-sectional characteristics of Cordyceps sinensis, we can effectively distinguish the true from the false: the cross-sectional characteristics of flowers can be seen in the false "grass" made of broccoli, and the stem characteristics such as epidermis and phloem can be seen in the pseudo socket made of plant stems Next month, in addition to the international academic conference "identification of precious medicinal materials", Lida is carrying out a number of research projects related to the modernization of traditional Chinese medicine, providing scientific basis for traditional Chinese medicine The research team led by Huang Wenxiu, associate professor of Department of biological and chemical science and technology, established a research platform for the prevention and treatment of menopausal women's osteoporosis with traditional Chinese medicine, which was used to detect the bone density of ovariectomized rats The results showed that the traditional kidney tonifying herbs, such as Epimedium, privet fruit and compound Erxian Decoction, could activate the receptor estrogen, which had a good effect on the treatment of osteoporosis Chen Shunhong's group, a full-time lecturer, is studying the pharmacological effects of traditional Chinese medicine on cardiovascular diseases It is found that hawthorn, Ganoderma lucidum, Mairong and other herbs have very good curative effects Recently, Guiling ointment has been found to have the effects of lowering blood lipid and anti arteriosclerosis The seminar of the Department of Applied Biology and chemical science and technology of PolyU will hold an international academic conference from the 4th to the 5th of next month Many experts from home and abroad will gather in PolyU to discuss the development of natural drugs.
