Abstract:
AIMTo study the chemical constituents of Ziziphus jujuba Mill var. Spinosa (Bunge) Hu ex. H. F. Chou.
METHODSTo separate the constituents by using various kinds of chromatography and identify their structures on the basis of spectral analysis.
RESULTSFive compounds were isolated and their structures were established as jujuboside D (1), jujuboside A (2), 5,7,4'-trihydroxyflavonol-3-O-beta-D-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (3), 6'''-coumaroylspinosin (4) and phenylalanine (5).
CONCLUSIONCompound 1 is a new compound named jujuboside D, 4 is reported as rotamer for the first time, 3 and 5 isolated from this plant for the first time.
