In our study, each part (flesh, white rind, and green rind) of watermelon was extracted using hydrothermal extraction method at temperatures ranging from 100 to 300°C at the intervals of 10, 30, and 60 min. We found that hydrothermal treatment has a significant bearing not only on tyrosinase inhibitory activity but also on neuronal cell protection of watermelon parts. The peak tyrosinase inhibitory activity (about 93%) was observed in both the flesh and green rind extracts at 300°C for 60 min.

The results of this study confirm that hydrothermal treatment may be an efficient processing method for the purpose of obtaining potent bioactive substances from watermelon.
