Microwave extraction technology of salviae miltiorrhizae

Abstract

The invention discloses a microwave extraction technology of salviae miltiorrhizae. The technology comprises the steps of taking the salviae miltiorrhizae, grinding, adding water, carrying out microwave extraction and concentrating. The parameters of the microwave extraction technology of the salviae miltiorrhizae are screened and optimized. The effective components of salviae miltiorrhizae extract prepared by the microwave extraction technology of the salviae miltiorrhizae are not denatured. The technology also has the advantages of being efficient, energy-saving, free from pollution, high in selectivity and the like.

Description

technical field [0001] The invention relates to a microwave extraction process of Salvia miltiorrhiza, and belongs to the field of medicine technology. Background technique [0002] Salvia is the dry root and rhizome of Salvia Mihiorrhiza Bge, a sage plant in the Lamiaceae family. It is clinically used to treat cardiovascular diseases such as angina pectoris and coronary heart disease. Salvia mainly contains water-soluble and fat-soluble components. The water-soluble components are mainly phenolic acids, such as salvianolic acid B, danshensu, protocatechuic aldehyde, etc. Among them, salvianolic acid B has the highest content, which is an effective ingredient for promoting blood circulation and removing blood stasis, and has the functions of protecting brain damage, heart and anti-oxidation. It is mostly used as an indicator component of process research. [0003] At present, during the extraction of Salvia miltiorrhiza, heat transfer heating is often used for extraction,...

Problems solved by technology

[0004] However, there are still a series of problems in the application principle, technology and engineering amplification of microwave technology for the extraction of active ingredients in traditional Chinese medicine: 1. The multi-channel and multi-target points of the curative effect of traditional Chinese medicine are based on the multi-components of traditional Chinese medicine. Is it possible to change the traditional heating method? It will cause changes in the quality or quantity of traditional Chinese medicine substances, thereby affecting the curative effect; 2. Microwaves have different effects on different plant cells or tissues, and the release of intracellular products also has certain selectivity, so it should be based on the characteristics of the product and Depending on its position in the cell, different processing methods are selected; 3. Microwave extraction is only suitable for products that are stable to heat, such as alkaloids, flavonoids, glycosides, etc., while for heat-sensitive substances such as proteins and peptides Etc. Microwave heating can lead to the denaturation and even inactivation of these components; 4. According to the principle of microwave heating, microwave extraction requires that the material to be processed has good water absorption, otherwise it is difficult for the cells to absorb enough microwave energy to destroy themselves and make them The contents are difficult to release
