Glycosides from Periploca forrestii / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents from n-BuOH fraction of the stems of Periploca forrestii.</p><p><b>METHOD</b>The compounds were separated and purified by various chromatographic techniques and recrystallisation. The physico-chemical properties and spectral data were applied to identify structure of these compounds.</p><p><b>RESULT</b>Six glycosides were isolated and identified as emodin-8-O-beta-D-glucopyranoside (1), physcion-8-O-beta-D-glucopyranoside (2), kaempferol-3-O-beta-D-galactopyranoside (3), kaempferol-3-O-alpha-L-arabinopyranoside (4), quercetin-3-O-beta-D-glucopyranoside (5), quercetin-3-O-alpha-L-arabinopyranoside (6).</p><p><b>CONCLUSION</b>These six compounds were obtained for the first time from this plant.</p>
