Abstract

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.
