Scientific proven health, beauty benefits and uses of Jujube plum

Anxiolytic / anxiety control /Sedative:

Study showed the ethanolic extract of seed of ZJ possessed anxiolytic effect at lower dose and sedative effect a higher doses.

Treatment for Chronic Constipation:

Study showed jujuba extract to be an effective and safe treatment for chronic constipation.

Anti-Diabetic / Hypolipidemic:

Study evaluating the hypoglycemic and hypolipidemic effects of a hydro-alcoholic extract of ZJ leaves in rats showed significant reductions of glucose, cholesterol, triglyceride and elevation of HDL. LDL reduction was not as significant.

Hepatoprotective / Antioxidant / Fruits:

Study investigating the hepatoprotective effect of methanolic extract of Zizyphus jujuba fruits in rat models of paracetamol- and thioacetamide-induced hepatic damage showed significant inhibition of biomarker elevation. Histopathological studies supported the biochemical findings. Study concludes a hepatoprotective activity probably due to its antioxidant effect.

Antioxidant:

Study showed the fruit extracts from Zizyphus jujuba had higher antioxidant activity than Hydrangea paniculata leaf extracts.

Spatial Memory Improvement / Antioxidant :

Study showed the co-treatment of Z. jujuba extract ameliorates ethanol-induced memory deficits, both in the acquisition process and retrieval process of spatial memory performance in rats. The improvement is attributed to the antioxidant properties of flavonoids present in the extract.

Rat Testes Reproductive Benefits:

Study in male Wistar rats evaluated the antioxidant effects of aqueous fruits extracts of Ziziphus jujuba on ethanol-induced oxidative stress. Results showed beneficial effects on ethanol-induced sperm toxicity, with enhancement of sperm motility and plasma membrane integrity.

Essential Oil / Hair-Promoting Effects:

Study evaluated the efficacy of essential oil from seeds of ZJ for hair growth. Applied to rats over shaved skin at different concentrations, results concluded ZJEO possesses hair growth promoting activity.

Weight-Reducing / Hypolipidemic / Hypophagic:

Study of hydroalcoholic extract of ZJ leaves showed the leaf extract to possess significant weight reducing, hypophagic and hypolipidemic properties in sucrose-induced obese rats.

Neurodegenerative Disease Preventive:

Study evaluated the role of jujube in bran benefits, its effect on neuronal differentiation of PC12 cells. Results showed jujube water extract induced neurite outgrowth of PC12 cells, induced phosphorylation of cAMP responsive element binding protein on PC12 cells. Results support the use of jujube as food supplement for the prevention of neurodegenerative diseases in which neurotrophin deficiency is involved.

Antimicrobial:

Study evaluated an aqueous-ethanol extract of jujuba seeds for antimicrobial activity against six bacterial strains. Results showed the extract is potent in inhibiting both gram-positive and gram-negative bacteria.

Benefits in Dyslipidemia in Obese Adolescents:

Study evaluated the effect of ZJ fruit in controlling dyslipidemia in obese adolescents. A triple-blind randomized placebo-controlled trial of 86 obese adolescents aged 12–18 with dyslipidemia. Results showed the fruits to be generally well tolerated, with potential favorable effects on serum lipid profile.

Antimicrobial / Fruits:

Study of crude extract of ZJ fruits showed a wide antimicrobial activity against tested microbes, with E. coli showing to be the most susceptible. Results suggest potential used for microbial infections, especially pediatric infectious diseases.

Hypolipidemic / Antiobesity:

Study of Z.. jujuba powder showed hypolipidemic and anti-obesity properties and did not show any negative impact on liver function as measured by ALT and AST.

Antipyretic / relieves fever / Leaves:

Study evaluated Z. jujuba for antipyretic activity in Brewer’s yeast induced pyrexia in rats. The antipyretic activity of the extract was comparable to paracetamol.

Anticancer / Human Hepatoma Cells:

Study evaluated the anti-cancer activity of ZJ and its mechanisms of action in human hepatoma cells (HepG2). Results showed the extract decreased the viability of the cells. The chloroform fraction was most effective, inducing a concentration dependent effect on apoptosis and a differential cell cycle arrest in HepG2 cells.

Antidiarrheal / Leaves:

Study evaluated the anti-diarrheal activity of an aqueous extract of leaves of ZJ in a castor oil and MgSO4 induced diarrhea model. Results showed significant inhibitory activity against castor oil and magnesium sulfate induced diarrhea. There was significant reduction in gastrointestinal motility by charcoal meal test in rats.

Antitumor / Breast Cancer / Fruit:

Study evaluated the beneficial effects of an aqueous extract of ZJ fruit on proliferation of breast cancer cells. Treatment caused dose- and time-dependent cytotoxic effect against an MDA-MB-468 cell line and significantly increased the total antioxidant capacity. In some groups, there was a preventive effect against anemia, lymphocytosis, and neutrophilia or significant decreased in enzyme markers. Results suggest ZJ ameliorates the adverse effects of NMU carcinogenesis and suggests potential in the treatment of mammary tumors in humans.

Immunomodulatory / Fruit:

Study investigated the role of jujube in regulating immune response. The IL-1ß and IL-6 cytokines in LPS-induced macrophages were suppressed by jujube water extract in both mRN and protein levels. In parallel, the inhibition on transcriptional activity of nuclear factor-kappa B was revealed in LPS-induced macrophages. Results showed bidirectional immunomodulatory activity by regulating expressions of proinflammatory cytokines in macrophages.

Cell-Mediated Immune Stimulation / Effect on Neutrophil Phagocyte Function / Leaves:

Study evaluated a hydroalcoholic extract of Ziziphus jujuba leaves on its effect on different in vitro methods of phagocytosis such as neutrophil locomotion and chemotaxis test, and in vitro immunostimulant activity by slide method and nitro blue tetrazolium test using human neutrophils. Results showed the extract stimulated cell-mediated immune system by increasing neutrophil phagocytic function.

Alpha-Amylase Inhibition / Anti-Diabetic Effect / Antioxidant:

Study investigated the inhibitory effect of H. persicum and Ziziphus jujuba on the activity of alpha-amylase. The methanolic extracts of HP and ZJ showed high inhibitory effect on alpha-amylase enzyme with IC50 of 307 and 867 µg/mL, respectively. The effect was comparable to acarbose in lowering the blood sugar levels in diabetic patients. Both plants showed high polyphenolic content suggesting a potent capacity in clearing of oxidants.

Effect on Peripheral Blood Cells / Fruit Extract:

Study evaluated the effect of a hydroalcoholic extract of the fruit of ZJ on peripheral blood cells in male Balb/c mice. Results showed a significant reduction in percentage of monocytes and neutrophils and an increase in the percentage of lymphocytes.
