摘要
为促进牡丹花资源的合理利用,以新鲜牡丹花为试验材料,乙醇为提取剂,在超声波辅助法的基础上,先通过对影响牡丹花多酚物质提取的4个因素提取温度、料液比、超声波时间和乙醇浓度进行单因素试验,再通过正交试验,确定牡丹花多酚物质提取的最佳工艺参数。结果表明:在超声功率600 W时,料液比为1∶40、提取温度60℃、乙醇浓度60%、超声波提取时间30min时为最优的提取条件;对牡丹花多酚的提取效果影响由大到小为提取温度、超声波提取时间、料液比、乙醇浓度;在最佳条件下,牡丹花多酚的提取含量达15.10%。
In order to promote the rational utilization of peony flower resources , with fresh peony flower as the experimental material , ethanol as the extraction agent , on the basis of the ultrasonic assisted method , first by the four factors influencing the peony extract polyphenols extraction temperature and ethanol concentration , solid-liquid ratio , ultrasonic time , single factor experiment and through orthogonal experiment , the optimum technological parameters of peony polyphenols extraction.The results showed that when the ultrasonic power 600W , material liquid ratio of 1∶40 , extraction temperature 60 ℃, 60% ethanol concentration , ultrasonic time 30min for the optimum extraction conditions;The effect of the extraction effect of polyphenols on the peony was from large to small to extract temperature , ultrasonic extraction time , liquid ratio and ethanol concentra-tion.Under optimal conditions , the extraction content of polyphenols of peony was 15.10%.
