Problems solved by technology

[0003] Among the several flavonoid extraction processes at present, the hot water extraction method has more impurities and the yield is not high; the alkali extraction and acid precipitation method is not feasible for the extraction of pine pollen flavonoids, and it is found that adding acid cannot effectively precipitate it; High; the process of enzyme extraction and alcohol extraction is simple and easy, with high yield and less impurities, but after trying it, it is found that the system will continue to generate fine particles, and the microporous membrane cannot solve the problem.

Abstract

The invention belongs to the field of biotechnology, in particular to a cosmetic containing pine pollen extract and a preparation process thereof. The present invention adopts the method of ethanol extraction and ethanol alcohol precipitation to extract pine pollen, solves the problem that fine precipitation is formed in the pine pollen extract, obtains stable pine pollen extract; The present invention uses suitable macroporous adsorption resin to carry out flavonoids Refining and purification; the concentrate is prepared with polyol aqueous solution to form pine pollen extract with polyol aqueous solution as the system. The obtained extract is stable, has good compatibility with cosmetics, and has little irritation to the skin. It is suitable for the application of pine pollen extract to The field of cosmetics provides the basis. The pine pollen extraction method adopted in the present invention has simple process, high yield, less impurities, strong operability, the obtained pine pollen extract has good stability, no precipitation, low risk of allergies, and good compatibility with cosmetic substrates. The obtained cosmetic has the effects of whitening, anti-aging, antibacterial and anti-inflammation.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a cosmetic containing pine pollen extract and a preparation process thereof. Background technique [0002] Since ancient times, pine pollen has been a treasure of food therapy and beauty treatment. Its application in skin care products has a long history. It is recorded in "Materia Medica Congxin" in the Qing Dynasty that "it is good for all kinds of acne and sores, and it is wet and rotten without scabs". Modern scientific research shows that pine pollen contains a variety of vitamins, proteins, amino acids, fats and other nutrients, known as "super miniature nutrition bank". Active ingredients such as pollen flavonoids have whitening, anti-aging, antibacterial and anti-inflammatory effects, and are often used in cosmetics. [0003] Among the several flavonoid extraction processes at present, the hot water extraction method has more impurities and the yield is not high; the alkali ...
