Problems solved by technology

But at the same time, the pressure of supercritical fluid extraction is relatively high, and the requirements for equipment are high; when a single extraction solvent is used, sometimes the solubility and selectivity are not enough, and the extraction capacity is small; during extraction, higher system pressure and increased solvent circulation are required to obtain Sufficient extraction volume, it is difficult to efficiently extract the target substance; equipment energy consumption is also large during operation

Abstract

This invention relates to a method of double frequency and supersonic alternating and strengthening ultra-threshold flow extraction of nature medical plant efficient components, which comprises the following steps: a, pre-processing of the materials, which comprises purifying, drying, grinding and filtering through ten to twenty pieces; using the extraction device to extract and separate the materials with its double frequency as 16kHz to 100kHz, power as 0 to 1000W, acoustic intensity as 0.2 to 1500W / cm2ú¼radiating time as two to five hours.

Description

technical field [0001] The invention relates to a method for extracting active ingredients of natural medicinal plants, in particular to a method for extracting active ingredients of natural medicinal plants by using double-frequency ultrasonic alternately intensified supercritical fluid. Background technique [0002] my country is a country rich in botanical medicine resources in the world, but due to the lag of production methods, there is a big gap in product quality compared with the world's advanced pharmaceutical companies, which greatly restricts the process of modernization of Chinese medicine in my country. my country's total export of traditional Chinese medicine accounts for only 1% of the world's total sales of medicines. The extraction method of active ingredients of traditional natural medicinal plants is generally solvent extraction. The method has the advantages of less residual effective components of the extract, good quality of the extract, low processing...
