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.

Key words: Salicornia herbacea, extracts, tyrosinase, inhibition effect
