Main Article Content
Abstract
Introduction: Extensive researches showed several pharmacological activities of dietary
plants, especially rice grains. Hence, development of health supplements form rice might be the strength
of Thailand. Methods: In this study, the four extracts from Thai rice cultivars, two from red (Hom-Dang,
Hom-Kularb-Dang) and two from black rice (Kum-Doi-Saket, Hom-Dum-Sukhothai2) were determined
of total phenolic and fl avonoids contents followed by antioxidant properties in vitro using 2,2-azinobis-(
3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS) radical scavenging, and lipid
peroxidation assays. Results: The Hom-Dang cultivar extract with the highest contents of phenolics
and fl avonoids showed the highest antioxidant activities. Conclusion: These fi ndings indicated that
Thai colored rice cultivars, especially the Hom-Dang variety, possess ultimate benefi ts to develop as
health supplements due to their antioxidative potentials.
