Microwave extracting method for Chinese medicine effective components

Abstract

The microwave extracting method of Chinese medicine effective components includes the following steps: soaking Chinese medicinal herbal pieces in 9-30 times water or organic solvent inside some container at room temperature for 1.5-5 hr; extracting inside one microwave oven of 600-4000 w power at 50-90 deg.C for 18-60 sec; and filtering to obtain filtrate containing the effective components. The simple extracting process can result in high extraction quality.

Description

technical field [0001] The invention relates to a method for extracting active ingredients of traditional Chinese medicine. Background technique [0002] The most commonly used method for extracting active ingredients from traditional Chinese medicine is the reflux method, and its extraction theory is based on the theory of penetration and diffusion. Extraction of traditional Chinese medicine is the extraction of effective substances in the cells of Chinese medicinal materials. These substances mainly exist in the vacuoles of the cells. To extract active ingredients, the solvent used for extraction must first penetrate the cell wall, cell membrane, cytoplasm, and vacuole membrane of the cells of Chinese medicinal materials and then enter the liquid. After the solvent entering the vacuole dissolves the effective substance, it will enter the main solvent from the vacuole through the vacuole membrane, cytoplasm, cell membrane, and cell wall by concen...
