[Studies on the structure of a new flavanonol glucoside of the root-sprouts of Agrimonia pilosa Ledeb].

Three compounds were isolated from benzene and acetone extracts of the root-sprouts of Agrimonia pilosa Ledeb, On the basis of physicochemical properties, spectroscopy (UV, IR, NMR, MS, CD, GC) and chemical degradation, two known compounds were identified as palmitic acid (Ⅷ)and daucosterol (Ⅸ), one new compound was elucidated as (2S,3S)-(-)-taxifolin-3-O-β-D-glucopyranoside (Ⅹ).
