摘要:

研究海蓬子水提物、醇提物、超声波水提物、超声波醇提物,分别经蒸馏浓缩和旋转蒸发仪蒸发浓缩所得浓缩物对酪氨酸酶活性的抑制作用。结果表明,蒸馏浓缩和旋转蒸发仪蒸发浓缩对提取物的抑制率几乎没有影响。这4 种提取物对以酪氨酸为底物的酪氨酸酶抑制作用存在显著性差异。抑制率分别为:水提物32.48%,醇提物62.37%,超声波水提物43.56%,超声波醇提物75.81%。其中海蓬子超声波醇提物表现出最好的抑制作用。

Abstract:

In this paper, the inhibitory effect of extract from Salicornia herbacea on tyrosinase activity was investigated. Four extracts including water extract, ethanol extract, ultrasound-assisted water extract and ultrasound-assisted ethanol extract were used as the materials to explore the inhibitory effect on tyrosinase activity. The results indicated that the extraction rate did not exhibit an obvious difference after distillation evaporation and rotary evaporation. However, the inhibition effect on tyrosinase had a significant difference among four extracts using tyrosine as the substrate. The inhibition rates on tyrosinase were 32.48% for water extract, 62.37% for ethanol extract, 43.56% for ultrasound-assisted water extract and 75.81% for ultrasound-assisted ethanol extract, respectively. Moreover, the ultrasound-assisted ethanol extract was the strongest enzyme inhibitor among them.
