Abstract:
OBJECTIVETo study the chemical constituents of Periploca calophylla.
METHODVarious chromatographic techniques were used to isolate the constituents, and their structures were identified by spectral and chemical methods.
RESULTTwo 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).
CONCLUSIONCompound 1 is a new compound. Compound 2 is reported for the first time from this plant.
