RESUMO
AIM: To study the chemical constituents of Ziziphus jujuba Mill var. Spinosa (Bunge) Hu ex. H. F. Chou. METHODS: To separate the constituents by using various kinds of chromatography and identify their structures on the basis of spectral analysis. RESULTS: Five 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). CONCLUSION: Compound 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.
