Application of eyela rotary evaporator in natural medicine research

Natural medicine refers to animal medicine, plant Wu medicine and mineral medicine which have been proved to have certain pharmacological activity by modern medical system Natural medicine is not equal to traditional Chinese medicine or Chinese herbal medicine With the development of society, people pay more and more attention to the negative impact of chemicals on human health and living environment; returning to nature and protecting the environment has become a trend thought to deal with the relationship between human and environment The research and development of natural drugs, including plant Wu drugs, animal drugs and marine drugs, have been developing with great momentum, and various artificial prohibitions on natural drugs have also become loose Natural medicine refers to the natural medicinal materials and preparations used under the guidance of modern medical theory Its sources include plants, animals and minerals, generally excluding substances derived from genetically modified animals and plants, substances fermented by microorganisms or chemically modified substances The research and development of natural drugs should pay attention to the following points: first, to guide the design and evaluation of clinical trials with modern medical theories; second, the determination of active ingredients should have sufficient basis; third, there should be sufficient test data to explain the rationality of prescription, the effectiveness and safety of non clinical and clinical; fourth, to ensure the sustainable use of resources 1 The use of natural drugs in the world up to now: there are Chinese medicine, Indian Buddhism medicine, Islamic medicine, European traditional herbal medicine, South American ethnic medicine and African ethnic medicine that have formed application system theory Among them, Chinese medicine is regarded as a natural drug system developed by Zui in the world 2 In terms of the scale of natural drug use, the total number of natural drugs in China alone has reached 12772, of which 11118 are from plants, 1574 are from animals and 80 are from minerals In addition, Zui, the dicotyledonous plant in angiosperms, accounts for 8598 3 From the analysis of the technical level of natural drug development and application, there are several situations as follows: API, which accounts for a large proportion in China's market, i.e traditional Chinese medicine; preparation or extract, which is made by some simple processing, most of the Chinese patent medicines come from this; effective chemical composition, the FDA of the United States is so required, but gradually deregulation 4 International hot natural drugs: anticancer drug paclitaxel and its derivatives; antimalarial drug Qinggao; cardio cerebrovascular drug ginkgolide; anti AIDS natural drugs, although there are many reports, but no drug can enter the clinical As the R & D cost of Western medicine is getting higher and longer, the natural medicine industry characterized by "natural therapy" will become a characteristic industry with development prospects for the global pharmaceutical industry Zui With the deepening of China's pharmaceutical system reform, natural pharmaceutical enterprises are facing fierce competition in the domestic and foreign markets All enterprises want to improve their competitiveness through transformation and upgrading, and seize the commanding heights of the industry Natural medicine extraction, rotary evaporators natural medicine research and application rotary evaporators is one of the indispensable experimental instruments Forward rotary evaporators + water pumps + cooling water devices are popularized: 1 Replace water pumps with diaphragm pumps 2 Added vacuum controller with diaphragm pump Synthesis and promotion of solvent recovery device to reduce the emission of organic gases to the laboratory Two rotary evaporators share a diaphragm pump and the glass components of the rotary evaporator of the solvent recovery device can be installed on the left and right sides - easy to use Dongnan Keyi (Guangzhou Dongnan Kechuang Technology Co., Ltd.) is the regional agent of Guangdong Province It is fully responsible for the marketing, sales and after-sales service of physical and chemical eyela products in Tokyo, Guangdong Province.
