1.5 Main Ellagitannin-Rich Medicinal Plants

Many plant species containing ellagitannins have been used for the
treatment of diseases, especially in Asia (Okuda et al. , 1992c). It is
notable that the comparison of the amounts and pharmacological
properties of ellagitannins and other components in plants shows that
some of these ellagitannins could be playing the main role in the
medicinal application of these plants (Fig. 1.11).
