Abstract

Abstract: To optimize the extraction and fermentation conditions of the polysaccharide of Coix kernel And studied its antioxidation and transdermal absorption effect, which provided reference for its application in anti-aging and transdermal absorption of human body. Results showed that the optimum conditions for the water extraction of Coix polysaccharide were 0.11, the temperature was 90 ℃, the time was 7; the best fermentation condition was Saccharomyces cerevisiae, the material liquid was 0.1, the time 54h,PH was 4.5; the extraction rate of coix polysaccharide was about 3 times of water. The antioxidant resistance of coix polysaccharide fermentation broth is better than that of water extract. The 24 h transmittance of coix polysaccharide fermentation broth was 1.14 mg/cm², and the 24h transmittance of water extract was 0.53 mg/cm².

Key words: coix polysaccharide, water extraction, fermentation, antioxidation, transdermal absorption
