Problems solved by technology

[0004] However, the existing bionic extraction technology only stops at extracting the active ingredients in traditional Chinese medicine into bionic liquids such as stomach and intestines, and the above-mentioned bionic extraction liquid has problems such as large solution volume, poor taste, and prone to gastrointestinal discomfort, etc. It can be used directly orally like a water decoction; of course, it can also be concentrated or dried, but because the above-mentioned bionic liquid contains a large number of biological enzymes and a series of complex compounds, during the heating process, The active ingredients contained in it are prone to side reactions (such as hydrolysis reactions, etc.), resulting in a decrease in the content of active ingredients

Abstract

The invention provides a traditional Chinese medicine extract method featuring combined utilization of the all biomimetic digestion technology and the cell membrane biomimetic solid phase extraction technology. The traditional Chinese medicine extract method mainly comprises the following steps: adding corresponding biomimetic digestive juice (simulated saliva, simulated gastric fluid, simulated duodenal juice and simulated bile) according to components and quantities of the digestive juice secreted by different digestive organs in a certain period of time in different digestive phases; then reasonably arranging digestion time of different digestive phases according to evacuation time of different dosage forms of the traditional Chinese medicine in human digestive organs to obtain all biomimetic digestive juice; and then obtaining a monolayer liposome loaded with a traditional Chinese medicine active constituent bundle according to distribution and absorption states of monolayer liposome-water distribution system simulated all biomimetic digestive juice in human stomach and intestines. In the invention, the all biomimetic digestion technology and the cell membrane biomimetic solid phase extraction technology are jointly adopted, the reaction conditions are mild and the method has the beneficial effects of maintaining conformation of the natural products and previous potency of the active constituents.

Description

technical field [0001] The invention relates to a method for extracting traditional Chinese medicines, in particular to a method for extracting traditional Chinese medicines by combining full bionic digestion technology and cell membrane bionic solid-phase extraction technology. Background technique [0002] The composition of traditional Chinese medicine is extremely complex, and various active ingredients cooperate with each other and act synergistically after entering the human body, and then play a role in the treatment of diseases. Traditional purification and separation technologies (such as decoction, reflux, immersion, percolation, etc.) , multi-effect film concentration and drying technology, vacuum belt drying technology, computer control technology, etc.) all use "pure" and "traditional" physical and chemical means, which have nothing to do with the synergy of the active ingredients of traditional Chinese medicine absorbed into the human body, so they are easy to ...
