A new oligosaccharide from Periploca calophylla / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of Periploca calophylla.</p><p><b>METHOD</b>Various chromatographic techniques were used to isolate the constituents, and their structures were identified by spectral and chemical methods.</p><p><b>RESULT</b>Two oligosaccharides were isolated from the chloroform part of P. calophylla and their structures were identified as 4-O-acetyl-beta-cymaropyranosyl (1-->4)-O-beta-D-cymaropyranosyl(1-->4)-O-beta-D-canaropyranosyl (1-->4)-O-beta-D-cymaropyranosy(1-->4)-O-oleandronic acid-delta-lactone(1), and perisaccharide B (2).</p><p><b>CONCLUSION</b>Compound 1 is a new compound. Compound 2 is reported for the first time from this plant.</p>
