Abstract

From the root barks of Araila elata Seem.(Araliaceae) three known saponins together with oleanolic acid and $\beta$-sitosterol $3-O-\beta$-D-glucoside were isolated. The saponins were identified as oleanolic acid $28-O-\beta$-D-glucoside were isolated. The saponins were identified as oleanolic acid $28-O-\beta$-D-glucopyranosyl ester, oleanolic acid $3-O-\beta$-D-glucuronopyranoside and oleanolic acid $3-O-\alpha$-L-arabinofuranoysyl-(1$\rightarrow$4)-$\beta$-D-glucuronopyranoside(narcissiflo on the basis of chemical and spectra data. The latter two saponins were isolated as their dimethylesters as well as monomethylesters.
