Chromatographic Analysis of Isoflavonoid Accumulation in Stressed Pisum Sativum
Carlson, R.E. and David DolphinH.
The isoflavonoid accumulation in CuCl2-stressed P. sativum was studied by high-performance liquid chromatography In addition to the pterocarpan phytoaloxin pisatin (I; R = OH, R1 = H), anhydropisatin (I; R R1 = bond), liquiritigenin (II), isoliquiritigenin, formononetin (III; R = OMe, R1 = R2 = H), pseudobaptigenin (III; R R1 = OCH2O, R2 = H) and afrormosin (III; R = OMe, R1 = H, R2 = OMe) were isolated. The relations of these metabolites to isoflavonoid biosynthesis and stress response in pea species are discussed.
