Abstract

Four new ellagitannins, potentillin (1), agrimoniin (2), and agrimonic acids A (3) and B (4), have been isolated from the roots of Agrimonia japonica (MIQ.) KOIDZ., and their structures, with an α-glucosidic linkage, were elucidated on the basis of spectral and chemical evidence. Potentillin (1) and agrimoniin (2) have also been isolated from Potentilla kleiniana WIGHT et ARNOTT.
