Abstract:
Objective To study the chemical constituents of Ranunculus ternatus.Methods The constituents were isolated and purified by column chromatographic methods.Their structures were elucidated by physicochemical properties and spectral analyses.Results Nine compounds were obtained and identified as robustaflavone-4′-methyl ether(Ⅰ),kayaflavone(Ⅱ),podocarpusflavone A (Ⅲ),bilobetin(Ⅳ),isoginkgetin(Ⅴ),amentoflavone(Ⅵ),4-oxo-5-(O-?-D-glucopyranosyl)-pentanoic acid-1O-butyl ester(Ⅶ),4-oxo-5-(O-?-D-glucopyranosyl)-pentansaeure-methyl ester(Ⅷ),benzyl alcohol O-?-D-glucopyranoside(Ⅸ).Conclusion Compounds Ⅰ-Ⅵ are obtained from the plants of Ranunculus Linn.for the first time,compound Ⅷ is a new natural product and compound Ⅸ is obtained from this plant for the first time.
