Abstract

The invention relates to a natural compound botanical antioxidant which comprises the plant raw materials as follows: 750-1200 parts by weight of lophatherum gracile, 15-40 parts by weight of the root bark of white mulberry, 20-50 parts of liquorice, 20-50 parts of artemisia capillaris flower and 1-6 parts by weight of Chinese dates. The invention also provides a preparation method of the natural compound botanical antioxidant, and the application of the natural compound botanical antioxidant in cosmetics for whitening and resisting ageing. According to the invention, the active ingredients of the natural raw materials are effectively extracted and reasonably matched, thus realizing the synergistic effect of different antioxidant active ingredients, and greatly improving the antioxidant activity.

Description

Technical field [0001] The invention relates to a compound plant antioxidant. Background technique [0002] With the deepening of the theoretical research on free radicals, diseases and aging, the application value of antioxidants has received increasing attention. Because synthetic antioxidants (such as BHT, BHA, etc.) have many side effects and have adverse effects on the liver, spleen, and lungs of the human body, the use of natural antioxidants to prevent and treat diseases has become a research hotspot. Natural plant antioxidants have the advantages of wide sources, high antioxidant activity, strong affinity with the body and high safety. Its antioxidant active ingredients are mainly derived from plant polyphenols, flavonoids, active polysaccharides, vitamins, proteins and amino acids, etc. [Zheng Deyong, etc., Plant Antioxidation and Research Prospects, Journal of Fujian Forestry College, 2004, 24(1): 88-91 ]. These antioxidant active ingredients play a role in the body ...
