From a medical point of view, extracts are generally divided into plant extracts (including Chinese medicine extracts) and animal extracts. In general, the extracts we talk about can generally be understood as plant extracts, traditional Chinese medicine extracts, and animal extracts. Plant extracts use plants as raw materials. According to the needs of the use of the extracted final product, through the process of physical and chemical extraction and separation, one or more active ingredients in plants are directionally obtained and concentrated without changing their active ingredients. products formed from the structure. According to the different components of the extracted plants, glycosides, acids, polyphenols, polysaccharides, terpenes, flavonoids, alkaloids, etc. are formed; according to the properties of the final product, it can be divided into vegetable oil, extract, powder, lens, etc. Plant extracts in my country are generally intermediate products, and are currently widely used, mainly used as raw materials or auxiliary materials for medicines, health food, tobacco, and cosmetics. There are also many kinds of raw material plants used for extraction. At present, there are more than 300 kinds of plants that have entered into industrial extraction.

The meaning of the extract

The extraction process overcomes the shortcomings of "coarse, large and black" of traditional botanicals and Chinese patent medicines. Let the active ingredients of plants be highly concentrated, so that the active ingredients are concentrated to a certain high content. At the same time, discard the useless and even harmful ingredients.

The most typical representative of the use of extracts is "the same source of medicine and food", which is the same source of medicine and food. As the name suggests, occasionally, small doses can be taken as ordinary food, and long-term, large amounts of consumption can play the role of medicine. Come. And through the extraction process, through the concentration extraction process, the medicinal effect of the medicinal and food homologous ingredients with less medicinal effect will be well exerted.

2. Disadvantages of traditional extracts

  (1) Water extraction process

Soak the raw materials in water, soak them for a period of time in a state of stirring, and heat them at high temperature to dilute the medicinal effect, which is similar to boiling traditional Chinese medicine. Finally, through the curing process, it is made into powder or paste. The disadvantage is that it is easy to destroy the taste, nutrients and effects of raw materials through high temperature cooking.

  (2) Organic solvent extraction process

Soak the raw material in an "organic solvent", such as alcohol. This allows the active ingredients to dissolve better. Due to the use of organic solvents, it is easy to cause denaturation and inactivation of certain biologically active macromolecules, which affects the efficacy of the drug.

3. Disadvantages of single extraction of a certain phytochemical component

As a method of scientific research, chemical purification is of great significance to the understanding of subtle science. However, if it is used as a commercial development method and research method, its weaknesses are:

  (1) People's understanding of plant active ingredients is a deepening process, not a one-step process. The history of phytochemistry shows that it is often the case that when we think we have discovered the active ingredient of a plant, but in fact it is only one of the active ingredients, it may only be easier to purify and find, and it may not be a more essential phytochemical Element.

  (2) More essential phytochemical components are often difficult to purify and difficult to quantify complex structures.

  (3) The inside of the plant itself is a miniature compound preparation. Its efficacy is often not only derived from one or a certain type of chemical components, but several types of chemical components all play a role, but there are primary and secondary factors. We guess that they are likely to have the relationship between the monarch, the minister and the envoy, just like the traditional Chinese medicine compound preparation. The effect of purified chemical monomers is not good. There are many such examples. For example: Ginkgo biloba extract has a good effect on cardiovascular and cerebrovascular. Vascular action, which proves that lactones are more important. However, the clinical verification results of pure lactone injection are far from ideal, far less than that of mixture injection. Those who have experience in the preparation of Chinese herbal medicines for intravenous injection know that although the quantifiable indicators of the injections made by purifying the plant components are much higher, the effect is far less than that of the mixture injections.

  (4) Purification of a certain chemical component greatly increases the industrial cost and wastes other available resources.

Fourth, the essence of traditional Chinese medicine extraction

The application theory of traditional Chinese medicine is relatively unique. Chinese medicine has four qi and five flavors. The four qi, also known as the four natures, refer to the medicinal properties of cold, hot, warm and cool. The five flavors refer to the pungent, sour, sweet, bitter, and salty properties of the medicine. The smell and taste of Chinese herbal medicines are different, and their curative effects are also different.

The traditional extraction process through high temperature or organic solvent extraction seriously destroys the "four properties" and "five flavors" of medicinal materials. The destruction of high temperature and organic solvents has reversed the "nature" of medicinal materials. Let the efficacy of the extract stay only in theory. Therefore, a low-temperature extraction process without the use of organic solvents has become the latest requirement for extraction processes in the new era.

5. Advantages of Tongyuan Extract

Tongyuan Gonghe extraction process adopts cell cavitation extraction process and enzymatic hydrolysis technology, which completely breaks the technical barriers of traditional extraction process. Cell cavitation extraction is the use of high pressure and hydraulic ultrasonic extraction, which realizes the extraction process at low temperature (not more than 50 ° C), the obtained product has high purity, high yield, and the extractant is pollution-free, almost completely retaining the medicinal materials. "Four natures and five flavors" is the perfect combination of traditional Chinese medicine and modern technology.

In the extraction process, the use of biological enzymatic hydrolysis technology breaks through the bottleneck of traditional material extraction technology in the production process, opens the cell wall of the medicinal materials, and retains the biological active substances to the greatest extent, and successfully applies science and technology to production. The problem of low content of active ingredients in extracts and poor effect.

The extract produced by Tongyuan Gonghe has the following advantages:

1. The "four natures and five flavors" of medicinal materials are preserved: the taste of traditional Chinese medicine extracts on the market is almost the same, while our extracts retain the original taste of medicinal materials and the important "four natures and five flavors" in traditional Chinese medicine. Here, you You can taste the different flavors of each Chinese herbal extract.

2. The whole process of low temperature extraction does not destroy the nutrition: the whole process does not exceed 50 ℃, which preserves the nutrition of the ingredients to the greatest extent.

3. Biological enzymatic hydrolysis technology retains activity.

4. Small molecule technology is easier to absorb.
