[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 technical field of biology, and particularly relates to a cosmetic containing pollen pini extracts and a preparation process thereof. According to the process, an ethanolextraction and ethanol alcohol precipitation method is used for extracting pollen pini; the problem of generation of tiny precipitates in the pollen pini extracts is solved; the stable pollen pini extracts can be obtained. Proper macroreticular resin is used for refining and purifying flavone; concentrated liquid is prepared by a polyhydric alcohol water solution; the pollen pini extracts using the polyhydric alcohol water solution as a system are formed; the obtained extracts are stable and have good compatibility with the cosmetics and small irritation on the skin; the foundation is providedfor the application of the pollen pini extracts to the field of cosmetics. The used pollen pini extraction method has the advantages of simple process, high yield, few impurities and high operability; the obtained pollen pini extracts have high stability; no precipitates are generated; the allergy risk is low; the compatibility with a cosmetic substrate is high; the obtained cosmetic has the whitening, anti-aging, antibacterial and anti-inflammatory effects.
Description
Technical field [0001] The invention belongs to the field of biotechnology, and in particular relates 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, and its application in skin care products has a long history. The Qing Dynasty "Materia Medica Renewal" recorded that pine pollen "is good for all kinds of acne damage and moist and not scabs." Modern scientific research shows that pine pollen contains a variety of vitamins, proteins, amino acids, fats and other nutrients, and is known as the "super micro-nutrient library." Among them, pollen flavonoids and other active ingredients have whitening, anti-aging, antibacterial and anti-inflammatory effects, and are often used in cosmetics. [0003] In the current flavonoid extraction processes, the hot water extraction method has many impurities and the yield is not high; the alkaline extraction a...
