Terpenoid glycosides from stem of Luculia pinceana / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents from n-BuOH portion of ethanolic extract from the stem of Luculia pinceana.</p><p><b>METHOD</b>The column chromatographic techniques were applied to isolate constituents. A combination of IR, FAB-MS, NMR and 2D NMR spectroscopy was used to identify structures.</p><p><b>RESULT</b>Seven compounds were isolated from the n-BuOH fraction and their structures were elucidated as vogeloside (1), epi-vogeloside (2), loganoside (3), loganin (4), cincholic acid 28-O-beta-D-glucopyranosyl ester (5), cincholic acid-3-O-beta-D-glucopyranoside, 28-O-beta-D-glucopyranosyl ester (6), cincholic acid-3-O-beta-D-glucopyranoside (7).</p><p><b>CONCLUSION</b>Compounds 1-7 were isolated from the genus for the first time.</p>
