Abstract

Objective To isolate ellagitannins from Lythri herba, determine their structures and develop chromatographic methods for their qualitative analysis. Results Five C-glucosidic ellagitannins–monomeric-vescalagin and castalagin together with new dimeric structures– salicarinins A–C, composed of vescalagin and stachyurin, vescalagin and casuarinin, castalagin and casuarinin units connected via formation of valoneoyl group, were isolated ...
