灰树花水上清液中不同极性提取物的功能成分及其抗氧化活性
Functional Components and Antioxidant Activities of Different Polarities Extracts from the Supernatant of Grifola frondosa
摘要
Abstract
In the study,petroleum ether,ethyl acetate,n-butanol and water with different polar solvents were used to the water-extracted supernatant of Grifola frondosa.The main functional components of different polar extracts were com-pared,and the antioxidant activities were compared by three methods:1,1-Diphenyl-2-trinitrophenylhydrazine(DPPH),2,2-diazo-bis(3-ethyl-benzothiazole-6-sulfonic acid)diammonium salt(ABTS+),hydroxyl(OH)free radical.The results showed that the polyphenol and protein contents of the n-butanol extract were the highest at 0.36％and 38.75％,re-spectively.The highest flavonoid content in petroleum ether and ethyl acetate extracts was 0.05％.The contents of triter-penoids and sterols in petroleum ether extract were 6.32％and 15.88％,respectively.The highest polysaccharide content in water extract was 30.11％.N-butanol extract showed the strongest antioxidant activity,and polyphenols may be the main component of antioxidant activity.Thirteen polyphenols and their derivatives were identified by LC-MS.This pro-vides a theoretical basis for the development of Grifola frondosa functional food or health products.关键词
