Study on Saponins Chemical Components from Aralia elata

OBJECTIVE:To study the saponins chemical components from Aralia elata.METHODS:Chemical compounds were isolated and purified by column chromatography,and their structures were identified by means of physical property and spectral data analysis.RESULTS:10 saponins were isolated and identified as Oleanlic acid 28-O-glucoside ester(1),Elatoside E(2),Elatoside F(3),3-O-β-D-Glucopyranosyl(1-3)-α-L-arabinopyranosyl oleanolic acid 28-O-β-D-glucopyranosyl ester(4),AraliasaponinⅣ(5),Stipuleanoside R2(6),Tarasaponin Ⅳ(7),Elatoside C(8),Spinasaponin A 28-O-glucoside(9),Araloside C(10).Compound 4 and 5 both were obtained from the plant for the first time.CONCLUSION:Results of the trial can provide reference for the further study of A.elata.
