A new oligosaccharide from Periploca calophylla.
OBJECTIVE
To study the chemical constituents of Periploca calophylla.


METHODS
Various chromatographic techniques were used to isolate the constituents, and their structures were identified by spectral and chemical methods.


RESULTS
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).


CONCLUSIONS
Compound 1 is a new compound. Compound 2 is reported for the first time from this plant.
