Pretreatment method for extracting plant effective components

Abstract

The invention relates to a pretreatment method for extracting plant effective components. Before extraction, wet basis plant materials are radiated by vacuum microwaves first, and then mechanical extrusion force and shearing force are repeatedly applied to plant materials after the radiation by vacuum microwaves by a screw extruder. After the pretreatment, the plant effective components of the plant materials are extracted subsequently according to a conventional method so that the extraction of the plant effective components has higher yield. The method also has the advantages of high microwave utilization rate, no damage to target effective components, short processing time and low energy consumption, can avoid an explosion accident of an organic solvent because the organic solvent is not used in the pretreatment of plants, and is suitable to be applied to industrial production.

Description

technical field

[0001] The invention relates to a method for extracting plant active ingredients, in particular to a method for pretreating plants before extracting plant active ingredients. The plant cell wall is broken through pretreatment, so that the extraction of plant active ingredients has a better yield. Background technique

[0002] my country has a vast territory, superior geographical and climatic conditions, and contains extremely rich natural plant resources. There are more than 30,000 species of higher plants alone, including 11,146 species of medicinal plants, which are the largest in the world in terms of variety and quantity. The foundation of Chinese herbal medicine for thousands of years. Although my country is a large country in the production of herbal medicines, it is not a powerful country in the production of herbal medicines. At present, my country's botanical medicines account for less than 5% of the world's botanical medicine market, most of which ...
