Abstract
Three new hydrolyzable tannins, geraniinic acids B and C, and phyllanthusiin F, were isolated from the water-soluble portion of 70% aqueous acetone homogenate of the Geranium thunbergii leaves and their structures were determined by spectroscopic and chemical methods. These tannins are regarded as modified metabolites of geraniin, a major component of this plant. Phyllanthusiins, which are tannins characteristic of the Phyllanthus species of Euphorbiaceae, were also isolated from this plant.
