[Studies on the structure of a new ellagic acid glycoside from the root-sprouts of Agrimonia pilosa Ledeb].

ABSTRACT

Four compounds were isolated from the root-sprouts of Agrimonia pilosa Ledeb. On the basis of physico-chemical properties, spectroscopy (UV, IR, NMR, MS) and chemical degradation, a new compound was elucidated as ellagic acid-4-O-beta-D-xylopyranoside (XV), and three known compounds were identified as agrimonolide (XIII), tormentic acid (XIV), and ellagic acid (XVI).
