Both SZJ-I and SZJ-II demonstrated significant sedative-hypnotic activities, as evidenced by shortened immobility time and potentiation of sodium pentobarbital-induced sleep. SZJ-II, with a higher saponin content, exhibited greater potency. SZJ-I and SZJ-II also protected against PCPA-induced neuropathological damages in the brain and modulated neurotransmitter levels (5-HT, dopamine, noradrenaline, glutamate), inflammatory markers (IL-6, IL-1β), and other signaling molecules (nitric oxide, prostaglandin D2) in plasma. Furthermore, SZJ-I and SZJ-II differentially regulated the expression of various receptors and enzymes in the hypothalamus and hippocampus, suggesting multiple mechanisms contributing to their sedative-hypnotic effects.

Experimental Study GABA Jujube Sleep
Methodology: An aqueous extract of jujube seeds (ZW) was fermented, following a starch-removing enzymatic degradation process, to increase its γ-aminobutyric acid (GABA) content, resulting in a fermented product (ZW-FM). The sleep-promoting effect of ZW-FM was evaluated using rodent models; specifically, sleep tests were performed on ICR mice with pentobarbital-induced sleep, while the electroencephalography analysis was undertaken in Sprague Dawley rats. Awakening relief effects of ZW-FM were assessed using a caffeine-induced insomnia model. To understand the mechanism, GABA receptor type A (GABA) antagonists were used.
Results: The groups given ZW-FM treatment displayed a longer sleep duration, particularly increased δ-wave time during non-rapid eye movement sleep, and reduced sleep latency. Particularly, the model treated with ZW-FM showed an increase in non-rapid-eye-movement sleep and a reduction in the REM sleep duration, brought about by caffeine treatment. The enhanced sleep induction caused by ZW-FM was hindered by GABA receptor antagonists, thereby validating the involvement of a GABAergic mechanism in promoting sleep.

Randomised Controlled Trial Jujube Sleep
The results show that the medicinal jujube seed capsule improved the sleep quality of postmenopausal women. Thus, it could be recommended as a safe plant with fewer complications compared to chemical and hormone drugs for the treatment of sleep disorders. Also, during the period of consuming jujube seed capsule in this study, except for a few cases of gastrointestinal disorders and in similar studies with this herbal medicine, consumers have reported no specific side effects. Therefore, considering that about one-third of adults in the world suffer from sleep disorders, the high prevalence of sleep disorders in postmenopausal women, and the lower cost of treatment by jujube seed capsule compared to other treatments, it is suggested implementing this treatment as a useful method in improving sleep quality in postmenopausal women.

Experimental Study Anxiety GABA system Serotonin
The research relied on a system biology method supported by Ultra Performance Liquid Chromatography Quadrupole Time of Flight Mass Spectrometry (UPLC-Q-TOF/MS) and Real-Time Quantitative Polymerase Chain Reaction (RT-qPCR). Initially, 35 phytochemicals were identified from the Jujube seed extract, which related to 71 anxiolytic targets. Further investigations, including protein-protein interaction, gene cluster, Gene Ontology, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways analyses, were conducted to identify the anxiolytic mechanisms of the extract.
The results highlighted that the main anxiolytic mechanisms of the Jujube seed extract were linked to the regulation of serotonergic and GABAergic synapse pathways. The extract's impact on the mRNA expressions of multiple gamma-aminobutyric acid type A (GABA) and serotonin (5-HT) receptors subtypes was verified in human neuroblastoma cells. Surprisingly, the extract (250 μg/mL) not only amplified the mRNA level of GABRA1 and GABRA3 alongside HTR1A, HTR2A, and HTR2B in untreated cells but also suppressed the overexpressed mRNA of GABRA1, GABRA2, HTR1A, and HTR2A in stress-induced cells.

Systematic Review Anti-Ageing Anti-Inflammatory Anticancer
The methodology of the research was primarily a comprehensive literature review of Ziziphi Spinosae Semen (aka Suan Zao Ren). The team explored the botanical characteristics, traditional uses, pharmacology, and discovered compounds in the seeds of Ziziphus Jujuba.
In regards to the results of the review, more than 150 compounds were identified in Ziziphi Spinosae Semen. These compounds, which mainly include terpenoids, flavonoids and others, show various biological activities. It was found that the seeds are particularly prominent in having sedative and hypnotic effects. Other properties discovered include antitumor potential, improvement to learning and memory, anti-inflammatory, antioxidative, anti-aging, alongside lower blood pressure and lipid levels. Traditional usage of the seeds for the treatment of insomnia, forgetfulness, headaches and dizziness were confirmed by the review.
