Supercritical safflower extracting process

Abstract

The supercritical safflower extracting process includes the following steps: the first extraction of the safflower material with supercritical CO2 as extractant, two-stage of decompression separation to obtain vegetable wax and volatile safflower oil, the second extraction of the safflower residue to obtain macromolecular non-polar matter, the third extraction of the safflower residue in the presence of entrainer and CO2 and decompression separation to obtain polar matter and entrainer. The present invention has high volatile safflower oil yield, realizes the extraction and separation of volatile oil and wax in one step and utilizes the non-polar matter in safflower effectively. The present invention has the advantages of high product concentration and capacity of producing high concentration medicine preparation easily.

Description

technical field

[0001] The invention relates to the technical field of medical processing and application, and belongs to the field of using supercritical CO 2 A method for extracting volatile oil, macromolecular non-polar substances and polar extracts contained in safflower. Background technique

[0002] Compositae safflower has a cultivation area of ​​30,000 to 40,000 hectares in my country, mainly concentrated in Xinjiang, Sichuan, Yunnan and Henan provinces. The flowers of safflower are used as medicine, which contain medicinal ingredients such as safflower yellow pigment, safflower glycosides, safflower polysaccharides and flavonoids. Clinical studies have shown that safflower extract has the effects of enhancing immunity, relaxing blood vessels, lowering blood fat, lowering blood pressure, stimulating the uterus, anti-inflammatory and anti-aging, etc. In addition, safflower volatile oil also has antibacterial effects. Therefore, safflower is widely used in the treatm...
