Article: Reports summarize food science research from Kyung-Hee University.

According to a study from Seoul, South Korea, "Black-colored rice (BCR), the main constituent of which is cyanidin-3-O-beta-D-glucoside (C3G), exhibits an anti-allergic effect, and orally administered C3G is mainly metabolized to protocatechuic acid in rats. Therefore, to understand the relationship between the metabolism of C3G and its pharmacological effect, we isolated C3G from BCR, anaerobically incubated it with fecal microflora, investigated its metabolite(s) by LC-MS/MS, and measured the antiscratching behavioral effects of C3G and its metabolites."

"C3G was metabolized to protocatechuic acid via cyanidin. Protocatechuic acid and cyanidin were identified ...
