BIOMIMETIC SYNTHESIS OF ELAEOCARPUSIN
Elaeocarpusin, a tannin-ascorbic acid condensation product, isolated from Geranium thunbergii as one of the water-soluble forms of tannin, has been biomimetically synthesized from geraniin and ascorbic acid, and shown to occur widely in the geraniin-containing species of plants.
