Abstract:
Riceberry rice, purple colored grains, which is cross-bred from the Khao Hom Nin
and Khao-Dawk Mali 105, has been developed in Thailand. It contains high amount of
phytochemical, mainly phenol compounds and anthocyanins which served as an antioxidant,
anti-inflammatory and decreased the risk of atherosclerosis. In this study, Riceberry and Gor-
Kor 31 rices obtained from Kanchanaburi Province were extracted with ethanol, methanol and
ethyl acetate using sonication. The concentration of 3 mg/mL of ethanol, ethyl acetate and
methanol crude extracts from Riceberry rice had the inhibition against mushroom tyrosinase
activity by 87.32%, 68.84% and 62.90%, respectively. Meanwhile, only ethanolic crude
extracts from Gor-Kor 31 rice showed 16.41% of anti-tyrosinase activity. In term of IC50
value, the various concentrations of ethanolic crude extracts from Riceberry rice were used to
evaluate the anti-tyrosinase activity. The result showed anti-tyrosinase activity with IC50 value
of 6.1 mg/mL. Furthermore, the total phenolic contents and DPPH scavenging activity of the
ethanolic crude extract from Riceberry rice were also determined. The total phenolic contents
were 55.2 ± 10.3 mg of gallic acid equivalents per gram crude extract, and DPPH scavenging
activity had the EC50 value of 181.5 ± 3.5 μg/mL. Our finding revealed that ethanolic crude
extract from Riceberry rice can potentially be used as a bioactive component for skin
lighteners based on the anti-tyrosinase properties and enriched natural antioxidants and
phenolic compounds.
