Studies on chemical constituents from stems and leaves of Jasminum lanceolarium / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical constituents in stem and leaves of Jasminum lanceolarium.</p><p><b>METHOD</b>The constituents of the EtOAc-soluble portion of the 95% ethanol extractive were isolated and purified by means of column chromatographic methods. Compounds were identified by their physical characteristics and spectral features.</p><p><b>RESULT</b>Eight compounds were isolated and identified as 5, 7, 3', 5'-tetrahydroxyflavanone (1), (2S)-5, 7, 3', 4'-tetrahydroxyflavan-5-O-beta-D-glucopyranosie (2), mannitol (3), nonacosane (4), trans-p-coumaric acid (5), cis-p-coumaric acid (6), ferulic acid (7) and, trans-cinnamic acid (8).</p><p><b>CONCLUSION</b>Compounds 14 were isolated from this genus for the first time. And compounds 5 and 6 were isolated from this plant for the first time.</p>
