Chemical constituents of Neoalsomitra integrifoliola / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of the n-BuOH fraction of 95% ethanolic extract of leaves of Neoalsomitra integrifoliola.</p><p><b>METHOD</b>The compounds were isolated with kinds of column chromatography. The structures were determined by MS and NMR spectroscopic techniques.</p><p><b>RESULT</b>Eight compounds were isolated from the n-BuOH fraction of 95% ethanolic extract and their structures were identified as 2-phenylethyl rutinoside (1), rutin (2), kaempferol-3-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (3), isorhamnetin-3-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (4), methyl chlorogenate (5), guanosine (6), adenosine (7), myo-inositol (8), respectively.</p><p><b>CONCLUSION</b>All compounds were isolated from this genus for the first time.</p>
