Phenanthrene constituents from rhizome of Arundina graminifolia / 中国中药杂志

<p><b>OBJECTIVE</b>To isolate and elucidate the constituents from rhizome of Arundina graminifolia.</p><p><b>METHOD</b>Theconstituents were extracted with 95% alcohol and isolated by chromatography on silica gel, Sephedax LH-20. The structures were determined by UV, IR, NMR and MS spectral analysis.</p><p><b>RESULT</b>Five phenanthrene constituents were identified as 7-hydroxy-2, 4-dimethoxy-9, 10-dihydrophenanthrene( I ), 4, 7-dihydroxy-2-methoxy-9, 10-dihydrophenanthrene ( II ), 2, 7-dihydroxy-4-methoxy-9, 10-dihydrophenanthrene ( III ), 7-hydroxy-2-methoxyphenanthrene-1,4-dione ( IV ), 7-hydroxy-2-methoxy-9, 10-dihydrophenanthrene-1,4-dione (V), respectively.</p><p><b>CONCLUSION</b>All compounds were isolated from rhizome of A. graminifolia for the first time.</p>

Chemical constituents from the rhizoma of Arundina graminifolia / 中国中药杂志

<p><b>OBJECTIVE</b>To isolate and elucidate the chemical constituents from the tuber of Arundina graminifolia.</p><p><b>METHOD</b>The compounds were extracted by 95% alcohol and isolated by column chromatography on silica gel, SephedaxLH-20 and ODS. The structures were determined by UV, IR, NMR and MS spectral analysis.</p><p><b>RESULT</b>Five compounds were isolated, and their structures were identified as (2E)-, 2-propenoic acid, 3-(4-hydroxy-3-methoxyphenyl)-decosyl ester (I), p-hydroxybenzyl alcohol (II), triacontanol (III) and p-hydroxybenzylethyl ether (IV), 3-hydroxy-5-methoxybibenzyl (V), respectively.</p><p><b>CONCLUSION</b>All compounds were isolated from the genus of Arundina for the first time.</p>
