ABSTRACT
<p><b>OBJECTIVE</b>To study chemical constituents of aerial parts of Gueldenstaedtia stenophylla.</p><p><b>METHOD</b>Chemical constituents were extracted with 95% alcohol and separated by repeated silica gel column, MCI, Sephadex LH-20 and RP C18 column chromatographic separation from aerial parts of G. stenophylla. Their structures were identified on the basis of the physiochemical properties and spectral data.</p><p><b>RESULT</b>Twenty-two compounds were separated and identified as apigenin (1), chrysoeriol (2), farnisin (3), diosmetin (4), 4', 7-dihydroxyflavone (5), luteolin (6), 3', 4', 7-trihydroxyflavone (7), quercetin (8), m-hydroxy benzoic acid (9), trans-ferulic acid (10), isovanillic acid (11), E-beta-hydroxy-cinnamic acid (12), salicylic acid (13), trans-p-coumaric acid (14), protocatechuic acid (15), (S) -2-hydroxyphenylpropionic acid (16), esculetin (17), 7-methoxy coumarin (18), phaseic acid (19), blumenol A (20), (6S, 9R)-roseoside (21), kaempferol-7-O-alpha-L-rhamnopyranoside (22).</p><p><b>CONCLUSION</b>Except compounds 1, 5, 8 and 15, the rest compounds were separated from genus Gueldenstaedtia for the first time.</p>
