Abstract
Several types of isoflavonoid-like immunoreactivity were detected in water-ethanolic extracts from Acca sellowiana (Berg) Burret, Psidium guajava L. and Psidium littorale Raddi (Myrtaceae) leaves. Chromatographic mobility of the immunoreactive substances was compared to that of authentic standards, revealing a spectrum of isoflavonoid metabolites in both genera. Aglycones as well as glycosides were detected, namely daidzin, genistin, daidzein, genistein, formononetin, biochanin A, prunetin, and several incompletely characterized isoflavones. Subsequent HPLC-MS study verified the identities of the main immunoreactive isoflavones and found several others, namely glycitein, glycitin, ononin, sissotrin, including the malonylated and acetylated glucosides. It is concluded that the isoflavonoid metabolic pathway is present in the Myrtaceae family.
