[Studies on the structure of a new isocoumarin glucoside of the root sprouts of Agrimonia pilosa Ledeb].
Trans-p-hydroxycinnamic esters VI and an isocoumarin glucoside VII were isolated from the benzene and acetone extracts of the root sprouts of Agrimonia pilosa Ledeb. On the basis of physicochemical properties, spectral data (UV, IR, NMR, MS, CI-MS-MS), GC and chemical degradation, VI was elucidated as trans-p-hybroxycinnamic esters of n-C22, n-C24-32, n-C34, alcohols, VII was elucidated as agrimonolide-6-Q-beta-D-glucopyranoside. VII and trans-p-hydroxycinnamic esters of n-C29-32 and n-C34 alcohols are new compounds.
