Abstract
Anthocyanins are water-soluble plant pigments that give rise to the red, purple, or blue colors observed in many crops. Especially purple pigment of colored rice represent biological activities has been an increased interest, due to the functional meal as a staple food. These health benefits have been attributed to antioxidant property of anthocyanin. However, there have been little genetic source for development of new and various colored rice variety. A recently developed new variety, 'Jungmo1020', showed an unique characteristic of blue color of rice grain hull. We identified the pigment petunidin-3-O-glucoside (Pt-3-G) as a major compound with a value of $176.3{\pm}2.3mg/100g$ (68.3%) from 80% MeOH with 1% HCl extracts by UPLC/MS/MS. The content of Pt-3-G in the extracts using a solvent of 100% MeOH with 1% HCl was the highest with the values of $183.8{\pm}2.5mg/100g$. In addition, these extracts showed excellent antioxidatative activities by DPPH and ABTs assay.
