摘要: 8-Hydroxy and 2,8-dihydroxy derivatives of the cytokinins, 6-(4-hydroxy-3-methyl-trans-2-butenylamino)purine N-6-(increment -2-isopentenyl)adenine, have been biosynthesized by xanthine oxidase oxidation. shown to be major intermdeiates. These compounds were tested for cytokinin activity in tobacco bioassay. The results suggest that substitution 8 position with a hydroxyl group causes less decrease than both 2 positions groups.
