1) Studies on the biosyhthesis of anthocyanins in autumn red leave were reviewed. 2) The methanol extracts of green and red leave of Sapium seliferum ROXB. were spectrophotometrically analysed. 3) A method of fractionation of leave pigments by chromatographic adsorption on AbOg was established, and the absorption spectrum of each fractions were measured. 4) The quantitative variations of flavonoids in relation to the development of autumn browning were measured by ethyl acetate extraction method. It was ascertained qualitatively that flavonoid content in autumn leave increases with the process of browning phenomenon, from green to red. From this fact, it was assumed with some probability that the precursor of anthocyanins in autumn leaves might not be flavonoids. 5) The anthocyanin in the leaves of Sapiun seliferum ROXB. is not paperchromatographycally identical with crysanthemin. The authors wish to express much thanks to Prof. Dr. Y. OSHIMA of Kyushu University, who afforded us experimental facilities for this study.
