花椒叶总黄酮超声辅助低共熔溶剂提取工艺优化及抗氧化性分析
Ultrasound-assisted extraction of total flavonoids from Zanthoxylum bungeanum Maxim.leaves with deep eutectic solvents and their antioxidant activity evaluation
摘要
Abstract
[Objective]To investigate the effect of deep eutectic solvent(DES)on the extraction rate of total flavonoids from Zanthoxylum bungeanum Maxim.leaves and analyze their antioxidant activity.[Methods]Using Z.bungeanum leaves as raw material and total flavonoid extraction rate as the evaluation index,this study performs ultrasound-assisted extraction to screen the optimal DES system.The scavenging capacities of the extracted total flavonoids against hydroxyl radicals(·OH)and DPPH radicals are determined.[Results]The highest extraction rate of total flavonoids is achieved using a choline chloride-ethylene glycol DES system(ncholine chloride∶nethylene glycol=1∶3)with 22%water content,a solid-to-liquid ratio(mZ.bungeanum powder∶Vsolvent)of 1∶47(g/mL),and ultrasonic time of 15 min.The total flavonoids from Z.bungeanum leaves exhibit a maximum hydroxyl radical scavenging rate of(63.89±0.26)%and a DPPH radical scavenging rate as high as(89.01±0.51)%.[Conclusion]DES demonstrates excellent efficiency in extracting total flavonoids from Z.bungeanum leaves,and the extracted total flavonoids possess strong antioxidant activity.关键词
