A new 24-nor-lupaneglycoside was isolated from the leaves of Acanthopanax trifoliatus. Based on spectroscopic data its chemical structure was determined as 24-nor-11$\alpha$-hydroxy-3-oxo-lup-20(29)-en-28-oic acid 28-Ο-$\alpha$-L-rhamnopyranosyl-(1$\rightarrow4)-\beta-D-glucopyranosyl-(1\rightarrow6)-\beta$-D-glucopyranosyl ester.

A new and two known lupane-triterpene glycosides were isolated from the hot MeOH fraction of the leaves of Acanthopanax gracilistylus W. W. Smith. Based on the physical properties and spectroscopic data, their chemical structures were determined as acankoreoside A (1), acankoreoside D (2), and $3{\alpha}-hydroxy-lup-23-al-20(29)-en-28-oic$ acid $28-O-{\alpha}-L-rhamnopyranosyl-(1{\rightarrow}4)-{$beta}-D-glucopyranosyl-(1{\rightarrow}6)-{\beta}-D-glucopyranosyl$ ester (3), respectively. To our best knowledge, compand 3 appears to be novel, which was named as wujiapioside A.

A new lupane triterpenoid saponin, 3, 11-dihydroxy-lupan-20-en-28-oic acid 28-o-$\alpha$-L-rhamnopyranosyl-(1$\rightarrow$4)-$\beta$-D-glucopyranosyl-(1$\rightarrow$6)-B-D-glucopyranosyl ester, have been isolated from the leaves of Acanthopanax koreanum Nakai (Araliaceae) together with one known flavonol glycoside, rutin. The structure were elucidated on the basis of spectral and chemical evidence.

Two lupane-type triterpenes, lupenone (1) and lupeol (2), a phytosterol, ${\beta}-sitosterol$ (3), two ursane-type triterpenes, $3{\beta}-acetoxy$ ursolic acid (4) and ursolic acid (5), a lignan, (-)-lyoniresinol $3a-O-{\beta}-D-xylopyranoside$ (6), and two flavanol glycosides, $catechin-7-O-{\beta}-D-xylopyranoside$ (7) and $catechin-7-O-{\beta}-D-apiofuranoside$ (8) were isolated from the stem bark of Sorbus commixta (Rosaceae). Their chemical structures were identified by physicochemical and spectroscopic methods.
