Sixty-two rice varieties and germplasms with different colors of seed coat were employed to study the contents and distribution of flavonoid. Results showed as follows:(1)In black and red and white rice, the mean flavonoid content in polished rice were(0.093?0.052)g·hg-1,(0.025?0.027)g·hg-1 and(0.007?0.014)g·hg-1 respectively, the mean flavonoid content in rice bran were(3898?0.940)g·hg-1,(0.706?0.349)g·hg-1 and(0.124?0.053)g·hg-1 respectively;(2)The flavonoid content in black rice were significantly higher than those of the red and white, mean flavonoid content in polished rice and rice bran of black rice were 372 times and 552 times respectively as much as those of red rice, and 1328 times and 3143 times respectively as much as those of white rice;the flavonoid content in red was significantly higher than that in white, mean flavonoid content of red rice were 357 times and 569 times respectively as much as those of white rice;(3)Mean flavonoid content in rice bran of various color rice were significantly higher than that in polished rice. The flavonoid content in rice bran were 4191 times,28.24 times and 1771 times respectively as much as that in polished rice.
