Problems solved by technology

The essence of this patent application is to first extract and then separate by chemical methods to obtain high-content punicic acid, that is, to remove other saturated fatty acids and unsaturated fatty acids by chemical methods to improve the purity of punicic acid. However, the punicic acid obtained by this method is only One of the conjugated unsaturated trienoic acids contained in pomegranate seeds; some chemical reagents are added in the extraction process, which inevitably causes some impurity pollution; moreover, the process of the method is complicated, there are many steps, and low temperature ( -20 to -10°C) process, methanol solvent recovery and heating process will also cause oxidation and denaturation; the process takes a long time

Abstract

The invention belongs to the field of extraction and separation technology of plant active ingredients, and relates to a preparation method for extracting high-content conjugated unsaturated trienoic acid pomegranate seed oil from plant seeds. The preparation method of a high-content conjugated unsaturated trienoic acid pomegranate seed oil of the present invention is to extract, separate and purify the conjugated unsaturated trienoic acid from pomegranate seeds, and is divided into the following steps: pulverizing the pomegranate seeds Finally, it is loaded into an extraction kettle for carbon dioxide extraction; the extracted carbon dioxide fluid is passed through a rectification column, and the supercritical rectification method is used to purify and remove impurities and other saturated fatty acids and monounsaturated fatty acids to obtain high-content conjugated unsaturated fatty acids. Saturated trienoic acid oil; then pass through a separation tank to separate other impurities and carbon dioxide. This method is a new process technology combining supercritical or subcritical extraction and rectification, which can prevent the oxidative denaturation of conjugated unsaturated trienoic acid, keep the product from being polluted, and obtain a high content of conjugated unsaturated trienoic acid. Saturated trienoic acid oil.

Description

technical field [0001] The invention belongs to the field of extraction and separation technology of plant active ingredients, and in particular relates to a preparation method for extracting high-content conjugated unsaturated trienoic acid oil from pomegranate seeds of plant seeds. Background technique [0002] Pomegranate seeds are one of the few plant seeds that contain conjugated unsaturated fatty acids in nature. The conjugated unsaturated fatty acids contain three conjugated double bonds, while the general conjugated unsaturated fatty acids only contain two conjugated double bonds. In addition, pomegranate seeds contain unsaturated fatty acids such as oleic acid and linoleic acid, as well as some flavonoids, isoflavones and polyphenols, which have anti-cancer, anti-virus, anti-oxidation, and hypolipidemic effects: [0003] It has been recorded in ancient Chinese medicine classics. For example, it is recorded in "Bielu of Famous Doctors" that "the pomegranate tastes s...
