Research on the extraction and anti-oxidation of flavonoids in Myrica rubra marc
摘要
Abstract
Myrica rubra is a specific fruit species in China, annual production of which is about 1 million tons, and Myrica rubra marc accounts for 10％ of total weight of the fruit. At present,the food industry based on Myrica rubra resources has a certain scale, while the utilization of Myrica rubra marc is still blank. The fractions were acquired from Myrica rubra marc by a series of steps including extraction and concentration, followed by extraction with petroleum ether, ethyl acetate, n-butanol. The anti-oxidative activities of the extracts were evaluated in vitro,including DPPH radical scavenging activity, Fenton action and reducing power methods. The results showed that n-butanol fraction and ethyl acetate fraction of Myrica rubra marc crude extracts exhibited strong scavenging abilities for DPPH free radical,their half-inhibitory concentration (IC50)were 30μg/mL and 40μg/mL, respectively,and were approximately 3.67 times and 2.75 times as much as that of Vitamin C( 1 10μg/mL).关键词
