ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents from the roots of Pterospermum heterophyllum.</p><p><b>METHOD</b>The chemical constituents of P. heterophyllum were isolated and purified by silica gel and sephadex LH-20 column chromatography. Their structures were identified on the basis of spectroscopic data and physicochemical properties.</p><p><b>RESULT</b>Nine compounds were isolated and identified as taraxerol (1), betulin (2), betulinic acid (3), sumaresinolic acid (4), 2-methoxy-5-hydroxy-1, 4-naphthoquinone (5), 5, 7-dihydroxy-6, 8-dimethylchromone (6), alpha-monpalmitin (7), palmitic acid (8), beta-sitosterol (9).</p><p><b>CONCLUSION</b>Compounds 2-7 were isolated from this genus for the first time.</p>
