ABSTRACT
<p><b>AIM</b>To study the chemical constituents of the stem of Fordia cauliflora of Yunnan province.</p><p><b>METHODS</b>The constituents were separated and purified by repeated silica column chromatography. The structures were elucidated by physical-chemical properties and spectroscopic data.</p><p><b>RESULTS</b>Six compounds were isolated from the ethanol extract of the stem of Fordia cauliflora. They were identified as 6-hydroxy-3-methoxy-6",6"-dimethylchromeno-(2", 3" 7, 8)-flavone (1), 3-methoxy-6-(3-methyl-but-2-enyloxy)-6", 6"-dimethylchromeno-( 2", 3" 7, 8)-flavone (2), 3, 6-dimethoxy-6", 6"-dimethylchromeno-( 2", 3" 7, 8)-flavone (3), 7-hydroxy-4'-methoxyisoflavone (4), 7, 4'-dihydroxyisoflavone (5) and karanjin (6).</p><p><b>CONCLUSION</b>Compounds 1 and 2 are new compounds. Compounds 3 -5 were isolated from the plant for the first time.</p>
