Jujube (Ziziphus jujuba Mill.) belongs to the Rhamnaceae family and is a popular fruit tree species with immense economic and nutritional value. Here, we report a draft genome of the dry jujube cultivar 'Junzao' and the genome resequencing of 31 geographically diverse accessions of cultivated and wild jujubes (Ziziphus jujuba var. spinosa). Comparative analysis revealed that the genome of 'Dongzao', a fresh jujube, was ~86.5 Mb larger than that of the 'Junzao', partially due to the recent insertions of transposable elements in the 'Dongzao' genome...

Chinese jujube (Ziziphus jujuba Mill.) is the most economically important member of the Rhamnaceae family and contains a high concentration of ascorbic acid (AsA). To explore the metabolic mechanism of AsA accumulation, we investigated the abundance of AsA in the fruit development stages, the leaf and flower of Z. jujuba cv Junzao, and the mature fruit of one type of wild jujube (Z. jujuba var. spinosa Hu, Yanchuan sour jujube). And the expression patterns of genes involved in AsA biosynthesis, degradation, and recycling were analyzed...

A strategy for rapid identification of target and non-target components from traditional Chinese medicines (TCMs) extracts were proposed by utilizing the UNIFI informatics platform for the computer-assisted UPLC/Qtof MS data analyses. Ziziphi Spinosae Semen (ZSS) contains various bioactive chemical ingredients, such as flavonoids, saponins, alkaloids and terpenes. Currently, there is no method that allows rapid and comprehensive identification of these multiple components. The rapid identification of chemical components in ZSS was successfully achieved with this strategy...

The impacts of petroleum contamination on the litter decomposition of shrub-grass land would directly influence nutrient cycling, and the stability and function of ecosystem. Ten common shrub and grass species from Yujiaping oil deposits were studied. Litters from these species were placed into litterbags and buried in petroleum-contaminated soil with 3 levels of contamination (slight, moderate and serious pollution with petroleum concentrations of 15, 30 and 45 g/kg, respectively). A decomposition experiment was then conducted in the lab to investigate the impacts of petroleum contamination on litter decomposition rates...

Dietary polysaccharides provide various beneficial effects for our health. We investigated the protective effects of wild jujube (Ziziphus jujuba Mill. var. spinosa (Bunge) Hu ex H. F. Chou) sarcocarp polysaccharides (WJPs) against experimental inflammatory bowel disease (IBD) by enabling enhanced intestinal barrier function. Colitis was induced in rats by the intrarectal administration of TNBS. We found that WJPs markedly ameliorated the colitis severity, including less weight loss, decreased disease activity index scores, and improved mucosal damage in colitis rats...

The polysaccharides from Ziziphus jujuba Mill. var. spinosa (Bunge) Hu ex H. F. Chou sarcocarp (PWJS) is evaluated for the chemical composition, antioxidant activity and hepatoprotective effect. The characteristics of PWJS were determined by FT-IR spectral and HPLC analysis. The antioxidant activity was investigated using in vitro systems. An in vivo study of PWJS against CCl4 induced liver injury was also conducted. HPLC analysis showed that PWJS is an acidic heteropolysaccharide, rich in glucose (38.59%), arabinose (23...

A pair of diastereoisomers, the N-glycosylated derivatives of dioxindole-3-hydroxy-3-acetic acid 1-2, and their conjugates with flavonoids 3-8, was isolated from the seeds of Ziziphus jujuba var. spinosa. Their structures were elucidated by NMR spectroscopic analyses, and the absolute configurations were determined by circular dichroism method. Compounds 3-10 were evaluated for the antioxidant capacity, using the radical absorbance capacity (ORAC) assay.

Jujube seed is a crude drug defined as the seed of Ziziphus jujuba Miller var. spinosa Hu ex H.F. Chou (Rhamnaceae) in the Japanese Pharmacopoeia (JP). Most of the jujube seed in the Japanese markets is imported from China, with the rest obtained from other Asian countries. Here we confirmed the botanical origins of jujube seeds from both China and Myanmar by a DNA sequencing analysis. We found that the botanical origins of the crude drugs from China and Myanmar were Z. jujuba and Z. mauritiana, respectively...

Semen Ziziphi Spinosae (SZS) has been used as a hypnotic-sedative medicine for thousands of years. Recently, SZS has also shown notable neuroprotective activities via anti-oxidative and anti-inflammatory effects in dementia animals. Jujuboside A (JuA), isolated from SZS, has been proved to be a major hypnotic-sedative component of SZS. In the present study, we firstly evaluated the effects of intracerebroventricular (ICV) injection of JuA (0.02 and 0.2mg/kg) for five consecutive days on cognitive impairment induced by ICV injection of Aβ 1-42...

Jujuboside B (1) is one of the saponins isolated from the seeds of Zizyphus jujuba var. spinosa, which are used as a well-known traditional medicine for the treatment of insomnia and anxiety in East Asian countries. This is the first study to investigate the antitumor mechanism of 1 in vivo and in vitro. The results showed that 1 induced apoptosis and autophagy in AGS and HCT 116 human cancer cells and also effectively suppressed tumor growth in a nude mouse xenograft model bearing HCT 116 cells. The apoptosis-inducing effect of 1 was characterized by annexin V/propidium iodide staining, sub-G1 phase increase, and caspase-3 activation...

Two rapid and simple HPLC methods with UV detector to determine three main compounds (magnoflorine, spinosin and 6'''-feruloyl spinosin) and evaporative light scattering detector (ELSD) to determine jujuboside A were developed for the chemical analyses of Zizyphi Semen. Magnoflorine, spinosin, and 6'''-feruloyl spinosin were separated with an YMC J'sphere ODS-H80 column (250 mm × 4.6 mm, 4 μm) by the gradient elution followed by the isocratic elution using methanol with 0.1 % formic acid and water with 0...
