1、Through the research to the brown rice in the variety for the pigment existence form and the constitution research, had discovered 4 kind of brown rice variety past, respectively is: High mallow element (FI), pelargonium 3,5 12 glucose past (FZ), a cornflower element 3 glucose past (said) and a cornflower element 3,5- two glucose past (F4), these 4 kind of brown rice variety past has much the common benzoin and adjoins nan after the base substitution structure, forms the model C6 C3 C6 three links altogether to clutch the system. Because altogether clutches the effect, on oxygen atom unpaired electron far away oxygen atom, nearness benzene ring, thus the weakening oxyhydrogen key, enhanced the phenol after the base on hydrogen atom activeness, the easy dehydrogenation to become the hydrogen donator .4 kind of members to have two the difference, one is besides the high mallow element for the past Yuan, other 3 kinds all form the variety past with the glucose; Two is 4 kind of variety pasts is different after the base number and the position, thus we come to the brown rice pigment physics and chemistry nature, the brown rice for medicinal purposes physiology function, thus will obtain the next brown rice variety glucoside the research direction.。
