摘要
龙眼壳含有丰富的具有抗衰老、美白功效的多酚物质。本研究拟以超声波辅助提取龙眼壳中的多酚,探索不同浓度的乙醇、料液比、超声频率、提取时间对龙眼壳多酚提取率的影响,采用单因素试验和正交因素进行提取工艺优化,对获得的提取物进行清除DPPH自由基和抑制酪氨酸酶活性测试。结果表明,龙眼壳多酚的最佳提取工艺为乙醇浓度60%,液料比1∶50(g/mL),超声频率40 kHz,超声时间60 min;龙眼壳多酚的清除DPPH自由基的能力与维生素C基本相当,对酪氨酸酶的抑制效果与曲酸基本相当,表明龙眼壳多酚可作为潜在的抗衰老、美白的天然化妆品原料。
Longan pericarp contains rich polyphenols with anti-aging and whitening effects.This project plans to extract polyphenols from Longan pericarp with ultrasonic assistance,explore the effects of different concentrations of ethanol,material to liquid ratio,ultrasonic frequency and extraction time on the extraction rate of Longan pericarp polyphenols,and optimize the extraction process with single factor experiment and orthogonal factors.The DPPH free radical scavenging activity and tyrosinase inhibitory activity of the extracts obtained in the experiment were tested.The results showed that the optimal extraction process of longan pericarp polyphenols was:ethanol concentration was 60%,liquid to material ratio was 1∶50(g/mL),ultrasonic frequency was 40 kHz,and ultrasonic time was 60 min.The ability of longan pericarp polyphenols to scavenge DPPH free radicals is basically equivalent to that of vitamin C,and the inhibitory effect on tyrosinase is basically equivalent to that of kojic acid,indicating that longan pericarp polyphenols can be used as a potential anti-aging and whitening natural cosmetic raw material.
