<p><b>OBJECTIVE</b>To study the chemical constituents of Davidia involucrata var. vilmoriniana.</p><p><b>METHOD</b>The chemical constituents were isolated by column chromatography on silical gel and sephadex LH -20. Their structures were elucidated on the basis of spectral analysis and physical constants.</p><p><b>RESULT</b>Seven compounds were isolated from this plant and the structures of them were identified as 3, 4, 5-trihydroxybenzoic acid (1), ellagic acid (2), maleic acid (3), quercetin (4), quercetin-3-O-beta-D-galactoside (5), 2alpha, 3alpha, 19alpha, 23-tetrahydroxyurs-12-en-28-oic-acid-28-O-beta-D-glucopyranosyl ester (6), ethyl brevifolin carbosylate (7), respectively.</p><p><b>CONCLUSION</b>Compounds 1-7 were isolated from this plant for the first time.</p>
