title: [Studies on the chemical constituents from the root-sprouts of Agrimonia pilosa Ledeb].
abstract: Five compounds were isolated from the petroleum ether extract of the root-sprouts of Agrimonia pilosa Ledob. A new compound, (R)-(-)-agrimol B (III), was elucidated by means of physical and chemical properties, spectroscopy (MS, IR, PMR, UV) and total synthesis. Four known compounds were identified as agrimophol (I), n-nonacosane (II), beta-sitosterol (IV) and pseudo-aspidin (V), the last one being previously known only as a synthetic entity. (S)-(+)-Agrimol B also was synthesized.
