Abstract

The distribution of geraniin and mallotusinic acid in Geraniaceae, Euphorbiaceae and other families in the Geraniales were investigated by HPLC. Geraniin composes the main part of the tannin in all of the investigated species of Geranium, but not in species of Pelargonium. The species of Geraniaceae lack mallotusinic acid. Geraniin was also detected in most of the species in the subfamily Euphorbioideae of Euphorbiaceae, although the amount was generally smaller than in Geranium, except for some woody species. Several species of Euphorbioideae contained mallotusinic acid. Characteristic of the subfamily Phyllanthoideae is the absence of mallotusinic acid and poor distribution of geraniin. Geraniin and mallotusinic acid were not detected in most of the species of other families in the Geraniales, except in Erythroxylum coca. Hyperin was found to be the main flavonol glycoside in most species of Geranium.
