Abstract:
A series of experiments were designed to study the relationship between the isoflavonoids andthe cotyledon wounded surfaces, the concentrations of jasmonic acid (JA) and the soaked time. 8 - day -old soybean (Glycine max [ L. ] Merri)cotyledons were soaked into jasmonic acid solutions. Isoflavonoidswere extracted by methanol and detected by high pressure liquid chromatography(HPLC). T he resultsshowed that there was no effect the surface wound on the isoflavonoids. The ratio of the 6″- O - malonyl-daidzin(MGD) and 6″- O - malonylgenistin(MGG)decreased and the ratio of daidzein and genistein in-creased, while the ratio of daidzin and genistin kept stable during 72 hours soaked period. The total a-mount of isoflavonoids in 20μM JA treated samples was the lowest and decreased most quickly among the 5concentrations used.
