성능/효과

• 1) The most breeds of blackish purple rice contained C₃G an amount of less then 50 mg by weight of 100g brown rice, only 6 breed contained above 200 mg. Among these, Heugjinju contained C₃G 500 mg per 100g unpolished rice are highest content.
• 2) As comparing blackish purple rice of high anthocyanin content (1500 mg per 100 g of brown rice) with that of low anthocyanin content (500 mg per 100 g of brown rice), it was revealed that quantity of PAL did not have the difference, but CHS was increased to about 70 times, DFR was increased to more than 100 times, and ANS was increased to near 2, 000 times.
• 3) MeOH extract from Heugjinjubyeo rice bran was fractioned by n~hexane, CH₂Q2 and n-BuOH in sequence, and then oryzafuran, quercetin, vanillic acid and protocatechuic acid was obtained by separation of the n-BuOH fraction to determine their structures. Among these compounds, oryzafuran was a natural compound found firstly in nature.
