STUDY ON CHEMICAL COMPOSITION OF THE SEEDS OF ZIZYPHUS JUJUBA MILL. VAR. SPINOSA HU

Chemical investigation of the seeds of Zizyphus jujuba Mill. var. spinosa Hu led to the isolation and structural elucidation of betulinic acid, 2-hydroxy-3-methoxybenzoic acid glucosyl ester and uridine, together with five flavone-C-glycosides. Their structures were characterized on the basis of MS, NMR spectroscopic data and comparison with reported data.
