摘要

目的：分离、鉴定猫爪草Ranunculus ternatus 块根的化学成分。方法：采用Sephadex LH-20及硅胶等色谱技术进行分离，制备HPLC纯化，根据理化性质及NMR等波谱方法进行结构鉴定。结果：从猫爪草中分离得到了8个化合物，分别鉴定为:4-氧代-5-（O-β-D-葡萄糖基）-戊酸（1），正丁基-β-D-吡喃果糖苷（2），腺苷（3），3--2-丙烯酸（4），5-羟甲基糠酸（5），3，4-二羟基苯甲醛（6），邻羟基苯甲酸（7），3，5-二甲氧基-4-羟基苯甲酸（8）。结论：化合物 1~3，7，8 为首次从该属植物中分离得到。

Abstract

Objective: To study the chemical constituents of Ranunculus ternatus. Method: Compounds were isolated by chromatography on silica gel and LH-20 columns

and purifided by PHPLC. Their physicochemical properties and spectral data were used to elucidate the structures. Result: Eight compounds were isolated and identified as 4-oxo-5-(O-β-D-glucopyranosyl)-pentanoic acid (1)

n-butyl-β-D-fructopyranoside (2)

adenosine (3)

3-[(3-hydroxy)-(4-β-D-glucopyranosyl)-phenyl]-2-propenoic acid (4)

5-hydroxymethyl furoic acid (5)

4-dihydroxybenzaldehyde (6)

salicylic acid (7)

syringic acid (8)

respectively. Conclusion: Compounds 1-3

7 and 8 can be isolated from the genus for the first time.
