- 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30 min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%。
- Abstract:
- 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 600 W,material liquid ratio of 1∶40,extraction temperature 60 ℃,60% ethanol concentration,ultrasonic time 30 min 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 concentration.Under optimal conditions,the extraction content of polyphenols of peony was 15.10%.
