目的 研究猫爪草的化学成分。方法 经柱色谱分离，理化常数和光谱分析鉴定化合物结构。结果 从乙酸乙酯部分得到5个化合物，分别为7—O-甲基圣草酚（Ⅰ）；对羟基苯甲酸甲酯（Ⅱ）；3-[（4-O-D-葡萄糖基）-苯基]-2-丙烯酸（Ⅲ）；3-[（3-羟基）-（4-O-D-葡萄糖基）-苯基]-2-丙烯酸（Ⅳ）；β-D-葡萄糖（Ⅴ）。结论 Ⅰ-Ⅳ系首次从毛茛属中得到。

英文摘要：

OBJECTIVE To study the constituents in the roots of Ranunculus ternatus, METHODS Column chromatography was used to separate constituents whose structures were elucidated by ESI-MS, NMR spectral data and hydrolysis method. RESULTS Five compounds were isolated and elucidated as stembin（ Ⅰ ）, methylparaben（ Ⅱ ）, 3-[ （4-O-D-glucopyranosyl）-phenyl]-2-propenoic acid（ Ⅲ ）, linocaffein （Ⅳ） and β-D-glucose（ Ⅴ ）. CONCLUSION Compound Ⅰ - Ⅳ are isolated from Ranunculus genus for the first time.
