ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of Sorbus tianschanica.</p><p><b>METHOD</b>The compounds were isolated and purified by recrystallization and chromatography with silica gel and resin. Their structures were identified by physicochemical properties and spectral analysis.</p><p><b>RESULT</b>Seven compounds were isolated from the EtOH extraction and six structures were identified as benzoic acid (1), benzyl-O-beta-D-glucopyranoside (2), ursolic acid (3), 2alpha-hydroxyursolic acid (4), hyperoside (5), quercetin-3-O-glucoside (6).</p><p><b>CONCLUSION</b>Compounds 1-5 were isolated from S. tianschanica for the first time.</p>
