- 摘要:
- 为促进蓝莓资源的综合利用，以乙醇为溶剂，超声提取，并采用紫外分光光度计对醇提液中熊果苷含量进行了测定，同时以水杨酸为阳性对照，测定了蓝莓果渣醇提液对酪氨酸酶的抑制作用。结果表明：蓝莓果渣含熊果苷0.18%，其提取液对酪氨酸酶有抑制作用，随含量增加抑制活性增加，且抑制作用与水杨酸低剂量组相当。
- Abstract:
- In order to promote the comprehensive utilization of Vaccinium uliginosum resources, ethanol was used as solvent for ultrasonic extraction, and the content of arbutin in ethanol extract was determined by ultraviolet spectrophotometer.At the same time, the inhibition of Vaccinium uliginosum pomace ethanol extract was determined by using salicylic acid as positive control.The results showed that the Vaccinium uliginosum pomace contained 0.18% arbutin, and the extract had inhibitory effect on tyrosinase.The inhibitory activity increased with the increase of the content, and the inhibitory effect was similar to that of salicylic acid low dose group.
