4. Conclusion
Mulberry fruit extract contains considerable amounts of anthocyanin,especially the extract from the purple-colored mulberry.Anthocyanin content is well correlated with antioxidant and its
tyrosinase inhibition activity. Anthocyanin, ascorbic acid and antioxidant properties of mulberry fruit extracts decreased signifi-cantly after exposure to heat at 70 C or light for 10 h. In order to obtain the best quality of mulberry fruit extract, all processes should be performed at a temperature lower than 70 C and should be kept in a light-resistant container.
