ABSTRACT
<p><b>OBJECTIVE</b>To investigate the chemical constituents of Ehretia thyrsiflora.</p><p><b>METHOD</b>Compounds were isolated with silica gel, Sephadex LH-20 and RP-C18 colum chromatography. Their structures were elucidated by means of physico-chemical properties and spectral analysis.</p><p><b>RESULT</b>Six compounds were isolated and identified as beta-sitosterol (1), ethyl caffeate (2), 2-methoxyl benzoic acid octyl ester (3), tetradecenoic acid, 2,3-dihydroxypropyl ester (4), daucoster (5), allantoin (6).</p><p><b>CONCLUSION</b>Compounds 1-5 were obtained from this species for the first time. Compounds 2-5 were obtained from the genus Ehretia for the first time.</p>
