合欢花黄酮超声辅助提取工艺优化及其抗氧化活性研究
Optimization of ultrasound-assisted extraction of flavonoid from Albizia flowers and its antioxidant activity
摘要
Abstract
Albizia flower was used as raw material to investigate the ultrasonic extraction of flavonoids from Albizia flower by single-factor and response surface experiments.The effects of ultrasonic power,solid-liquid ratio,ethanol concentration,and ultrasonic time on the content of flavonoids extracted from Albizia flower were studied.Furthermore,the types,content,and antioxidant activity of flavonoids in Albizia flower were explored.The results showed that the optimal process for the optimized extraction of flavonoids from Albizia flowers with the response surface method was as follows:ultrasonic power of 120 W,feed-to-liquid ratio of(1∶8)g/mL,ethanol concentration of 80%,extraction time of 100 min,resulting in a flavonoid content of Albizia flowers 9.23%.When the antioxidant activity of Albizia flower flavonoid extract was tested after vacuum freeze-drying,it showed that the DPPH free radical scavenging rate was 67.15%when the Albizia flower flavonoid concentration was 7 mg/mL;and the ABTS free radical scavenging rate was 83.27%when the Albizia flower flavonoid concentration was 100 μg/mL;LC-MS tests revealed that there were 27 types of Albizia flavonoids,among which the amount of quercetin was the highest,reaching 412.472 μg/g,followed by rutin,with a content of 88.753 μg/g.The isoquercitrin ranked the third place with the content of 83.641 μg/g.This study provides a theoretical basis for the development and utilization of Albizia flowers in food.关键词
