木豆叶球松素的超声提取工艺及其抗氧化活性研究
Study on optimization of ultrasonic-assisted extraction technology and its antioxidant activity of pinostrobin from pigeonpea leaves
摘要
Abstract
Based on single-factor experimental results,effects of four parameters including methanol concentration,extraction time,extraction temperature and ratio of solid to liquid on the extraction yield of pinostrobin from pigeonpea leaves were optimized by orthogonal test design,and the antioxidant capacity of methanol extract (ME) was evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging ability.Optimal extraction conditions were obtained as follows:methanol concentration 80％,extraction time 60min,extraction temperature 50℃ and solid-liquid ratio 1∶40(g/mL).Under optimum conditions,the extraction yield of pinostrobin reached 1.832mg/g,and ME of pigeonpea leaves exhibited good antioxidant activity with an IC50 value of 0.281mg/mL.Ultrasonic-assisted extraction technology established in the study possessed the advantages of high efficiency and ease of operation,which was suitable for the extraction of pinostrobin from pigeonpea leaves.关键词
