超声辅助半仿生法提取半边莲黄酮苷及抗氧化性研究
Study on ultrasonic wave-assisted Semi-bionic extraction and antioxidant activity of flavonoid glycoside from Herba Lobelia Chinensis
摘要
Abstract
Studied the optimal technical paramters for extraction flavonoids glycosides from Herba Lobelia Chinensis by ultrasonic-assisted semi-bioni extraction and its antioxidant activity.The experimental results showed that the optimal conditions were as follow; 70% (v/v) of ethanol - water ( as the extracting solvent), 1:40g/mL of solid to liquid ratio,70W of ultrasonic power and 25min of ultrasonic time.The content of flavonoids glycosides was found to be 4.6975mg/g by the orthogonal design under the optimal conditions. The results of antioxidation showed that flavonoid glycosides from Herba Lobelia Chinensis had a certain scavenging effect on hydroxyl free radical and superoxide anion free radical.The reduction capability increased with increasing flavonoid glycosides concentration in experimental.Therefore,flavonoid glycosides were a powerful natural antioxidant.关键词
