超声辅助低共熔溶剂提取车前草总黄酮的工艺研究OA北大核心CSTPCD
Optimization of extraction technology of total flavonoids from Plantaginis Herba with ultrasonic-assisted deep eutectic solvents
为探究车前草总黄酮的最佳提取工艺,以总黄酮提取率为评价指标,在提取温度、反应时间、低共熔溶剂含水量、摩尔比等单因素试验基础上进行响应面优化.结果表明,车前草总黄酮的最佳提取工艺为提取温度34℃,反应时间41 min,低共熔溶剂含水量47％,摩尔比2.2∶1.在此条件下,总黄酮的提取率可达6.28％.研究为车前草的开发及综合利用提供理论支撑.
In order to explore the optimal extraction process of total flavonoids from Plantaginis Herba,total flavonoid extraction rate was used as the evaluation index,and response surface optimization was carried out based on the single factor experiments such as extraction temperature,reaction time,water content of deep eutectic solvents and molar ratio.The results show that the optimal extraction process parameters of total flavonoids from Plantaginis Herba are extraction temperature 34 ℃,reaction time 41 min,DESs water content 47％,and molar ratio 2.2∶1.Under these conditions,the extraction rate of total flavonoids can reach 6.28％.The study provides theoretical support for the development and comprehensive utilization of Plantaginis Herba.
