Supercritical extraction method for extracting effective components from pine pollen

Abstract

The invention relates to a supercritical extraction method for extracting effective components from pine pollen. According to the supercritical extraction method, an ester component can play a lipid barrier protection role in skin care products and is closely relevant with efficacies of preserving moisture, resisting inflammation and the like; a flavonoid component has skin care activities of resisting ageing and inflammation and the like; and an alkaloid component has a functional structure group similar to ceramide and is capable of regulating physiological functions of the skin, preserving the moisture and delaying the skin ageing. The functional activities of the three components supplement each other so as to achieve a synergistic interaction effect, so that the utilization rate of the effective components of the pine pollen in terminal products is increased. The invention relates to three-level extraction, except the extraction of common ester components, two substances, namely flavonoid and alkaloid, which are difficultly extracted are extracted from residues by virtue of a supercritical extraction technique, so that the extraction rates of the components, such as flavonoids, are increased, the utilization efficiency of the pine pollen is improved, the waste of resources is avoided, meanwhile, the effective substances in the pine pollen are furthest maintained, and the biological activity is enhanced.

Description

technical field [0001] The invention belongs to the technical field of pine pollen extraction, in particular to a supercritical extraction method for extracting active ingredients from pine pollen. Background technique [0002] Pine pollen is a variety of pollen that can be used both for medicine and food. As a traditional Chinese medicinal material, its history of both medicine and food has exceeded a thousand years, and it has various health effects such as prolonging life. Pollen flavonoids have a variety of beauty and skin care effects, and studies have shown that they have good performance in anti-radiation, anti-aging and anti-oxidation. [0003] At present, most of the extraction and separation processes of pine pollen are concentrated in the research of water extraction and alcohol extraction process, and it is difficult to achieve the purpose of separation and purification of the ester components and alkaloid components in pine pollen; The ester components such as ...

Problems solved by technology

[0003] At present, most of the extraction and separation processes of pine pollen are concentrated in the research of water extraction and alcohol extraction process, and it is difficult to achieve the purpose of separation and purification of the ester components and alkaloid components in pine pollen; The ester components such as sterols, glyceric acid, etc., but the active ingredients involved in the traditional extraction process are rarely involved, so it is difficult to maximize the use of active ingredients in pine pollen
