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-beta-D-glucopyranoside (X).
从龙牙草根茎的苯提取物和丙酮提取物中分离出三种化合物。根据理化性质、光谱学（紫外、红外、核磁共振、质谱、圆二色光谱、气相色谱）以及化学降解方法，鉴定出两种已知化合物为棕榈酸（VIII）和胡萝卜苷（IX），一种新化合物被阐明为（2S，3S）-（-）-紫杉叶素-3-O-β-D-吡喃葡萄糖苷（X）。
