A method for extracting active ingredients of natural products by mixing ethanol and subcritical fluid

A subcritical fluid and natural product technology, which is applied in the extraction of active ingredients of natural products by mixing ethanol and subcritical fluid, and simultaneously extracts water-soluble and fat-soluble active ingredients in natural products. Both water-soluble and fat-soluble active ingredients are extracted, the water-soluble ingredients cannot be fully extracted, and the polysaccharide structure is destroyed, so as to achieve the effect of increasing selectivity and efficiency, short cycle time and high extraction degree

Abstract

The invention discloses a method for extracting effective components of natural products and relates to a method for extracting water-soluble and fat-soluble effective components in the natural products simultaneously, particularly to a method for extracting the effective components of the natural products through mixing of ethyl alcohol and a sub-critical fluid, and belongs to the field of extraction of the effective components of the natural products. According to the method which is a new extraction and separation technology, the ethyl alcohol and the sub-critical fluid are mixed to serve as an extracting solvent, in a closed, oxygen-free and low-pressure extracting tank, all the components are separated and purified respectively through three steps, namely, extraction, desolventizing as well as membrane separation-macroporous adsorbent resin combined separation, and finally, high-purity water-soluble component and fat-soluble component extracts of the natural products are obtained; the method has a broad application prospect in the industry.
