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.
从龙牙草根芽的石油醚提取物中分离出了5种化合物。通过物理和化学性质、光谱学（质谱、红外光谱、质子磁共振谱、紫外光谱）以及全合成，阐明了一种新化合物，即（R）-（-）-仙鹤草酚B（III）。鉴定出4种已知化合物，分别为仙鹤草甲素（I）、正二十九烷（II）、β-谷甾醇（IV）和伪绵马素（V），最后一种化合物此前仅作为合成物为人所知。还合成了（S）-（+）-仙鹤草酚B。
