Isolation and structure identification of chemical constituents from Viscum liquidambaricolum / 药学学报

ABSTRACT

<p><b>AIM</b>To study the chemical constituents of Viscum liquidambaricolum Hayata.</p><p><b>METHODS</b>Various chromatographic techniques were used to separate and purify the compounds. Their spectral data (MS,IR,NMR) were measured for structure identification.</p><p><b>RESULTS</b>Five compounds were isolated from Viscum liquidambaricolum and their structures were identified as trans-cinnamic acid (I), oleanolic acid (II), chrysin (III), eriodictyol (IV) and liquidamboside (V).</p><p><b>CONCLUSION</b>Liquidamboside (V) is a new compound, the known compounds I - IV were isolated from this plant for the first time, I, III, IV were isolated from Loranthaceae for the first time.</p>
