Abstract

Two flavones are isclated from leaf and stem extracts of panicle-differentiating to flowering rice (Oryza sative L. ) plants. Based on the spectroscopy analysis, the structures of these two compounds are identified as 5,7,4'-trihydroxy- 3',5'-dimethoxy-foavone (A) and 5,4'-dihydroxy-3',5'- dimethoxy-7-β-D-glucosyloxy-foavone (B), respectively. These two compounds were able to strongly induce vir gene expression of Agrobacterium tumefaciens.
