I. Types of traditional Chinese medicine extracts
Extract of traditional Chinese medicine is a kind of material base with relatively clear efficacy and strict quality standard obtained by using advanced technology to extract and separate Chinese herbal medicine or Chinese herbal medicine compound. It is a new product form in the International natural medicine health product market. It is the main raw material of plant pharmaceutical preparations and can be widely used in natural health products. According to the nature of the extract, it can be divided into four categories: mono-flavor Chinese medicine extracts(using different extraction methods) such as Ganoderma lucidum, Ginseng, ginkgo biloba, Luohan fruit, immortal grass, etc.; Compound Chinese medicine extracts such as Buzhong Yiqi Decoction, Sishen Decoction, Liuwei Dihuang Pill, Qibaomeidan, Xiaoyao San, etc.; Traditional Chinese medicine monomers such as Ginkgo flavonoids, Ginkgo lactone, soybean isoflavones, Ganoderma lucidum polysaccharides, pyrethelin, etc.. The derivatives of traditional Chinese medicine extracts such as indigo of Qingdi are still controversial
The chemical composition of the standard extract of traditional Chinese medicine is usually an active group of active ingredients composed of a variety of pharmacological active substances in a certain proportion. It has the characteristics of multiple components of traditional Chinese medicine and well embodies the efficacy of the original Chinese herbal medicine and compound specific Chinese medicine. However, it has considerable advantages in quality control.
Traditional Chinese Medicine Extract II. Equipment and Methods of Traditional Chinese Medicine Extract
Commonly used extraction methods(such as frying, reflux, impregnation, infiltration, etc.) have the disadvantages of large loss of active components, long period, many processes, and low extraction rate in terms of retaining active components and removing invalid components. In the past ten years, many new technologies and methods have appeared in the extraction of traditional Chinese medicine. The application of these new technologies and methods has made Chinese herbal medicine extraction not only conform to traditional Chinese medicine theory, but also achieve the purpose of improving the yield and purity of active ingredients.
Traditional Chinese medicine extract has high requirements for production conditions and production technologies. Many advanced extraction, separation, purification and drying equipment and technologies are used in the production of traditional Chinese medicine extracts. The application of these technologies and equipment has greatly improved the engineering technology and equipment of traditional Chinese medicine pharmaceuticals. level.
Chinese medicine extract III. Standards for Chinese medicine extracts
The vast majority of traditional Chinese medicine extracts are mainly exported. This may be related to many differences in the Chinese medicine community's views on traditional Chinese medicine extracts. Many people think that traditional Chinese medicine extracts are very different from traditional Chinese medicine tablets and can not even be called Chinese medicine. Because there are many subtle chemical reactions in the frying process, this is the effect that Chinese herbal extracts can not achieve when mixed. In fact, it has been confirmed in the study of Chinese medicine granules by a company in Guangdong that Chinese herbal medicine extracts can maintain most of the characteristics of Chinese medicine. At the same time, with the Advancement of technology, the effective ingredients of Chinese medicine are clear, and the standards of Chinese herbal medicine in Chinese Pharmacopoeia are used as a reference. It will be able to formulate the initial Chinese medicine extract standard that conforms to the characteristics of traditional Chinese medicine and is accepted by the world as soon as possible, and will continue to improve during the implementation process. This is also in line with the current development law of plant drugs.

Guan Ya brand SFY Series / WL Series
Product description:
Shenzhen Guanya Hydrometer Co., Ltd. is a factory that specializes in the development of rapid water meter in China. Since 1998, it has met with a registered capital of 50 million, focusing on the application and research and development of rapid hydrometer. At present, there are companies in Shenzhen and Changchun, and Shenyang has offices to provide rapid hydrometers for colleges and universities, scientific research institutions, inspection units, enterprise units, and self-employed purchase and trading companies throughout the country.
In the past ten years, Guanya has won praise from users for its excellent product quality and good after-sales service.
In response to market demand, Shenzhen guanya hydrometer new launch of wL series liquid crystal touchscreen rapid moisture meter, the instrument breaks through the traditional hydrometer operating habits, the new hydrometer uses seven-inch liquid crystal touchscreen, simple and convenient operation, clear and clear data.
Guanya brand WL series LCD touchscreen hydrometer is the Shenzhen Guanya hydrometer company in response to the National science and technology development strategy, while meeting the customer's demand for testing, Shenzhen Guanya recently launched the sixth generation of Guanya WL series rapid water meter inspection equipment to the market., While inheriting the excellent performance of Guanya's previous equipment, the WL series has more modern technology highlights and achieved a highly intelligent design concept.
The high-resolution seven-inch LCD large screen of the Guanya brand WL series can directly test parameters and condition settings on the LCD screen through the full-screen touch mode, thus realizing the human-machine integrated operation mode. Changed the disadvantage that the device can not watch the data process changes in real time. After the analysis is completed, the instrument screen automatically locks the final data. There is no need for personal care and maintenance of the experimental process. Operators do not need to conduct training, look at the manual or product operation process can be fully mastered and operated, and according to the instructions on the manual, you can simply deal with the various phenomena that occur in the work of the equipment.
