This study aims to study the effective substance and mechanism of Ziziphi Spinosae Semen extract in the treatment of insomnia based on serum metabolomics and network pharmacology. The rat insomnia model induced by p-chlorophenylalanine(PCPA) was established. After oral administration of Ziziphi Spinosae Semen extract, the general morphological observation, pentobarbital sodium-induced sleep test, and histopathological evaluation were carried out. The potential biomarkers of the extract in the treatment of insomnia were screened by ultra-high performance liquid chromatography-mass spectrometry(UHPLC-MS) combined with multivariate analysis, and the related metabolic pathways were further analyzed. The "component-target-pathway" network was constructed by ultra-high performance liquid chromatography coupled with quadrupole-Exactive mass spectrometry(UHPLC-Q-Exactive-MS/MS) combined with network pharmacology to explore the effective substances and mechanism of Ziziphi Spinosae Semen in the treatment of insomnia. The results of pentobarbital sodium-induced sleep test and histopathological evaluation(hematoxylin and eosin staining) showed that Ziziphi Spinosae Semen extract had good theraputic effect on insomnia. A total of 21 endogenous biomarkers of Ziziphi Spinosae Semen extract in the treatment of insomnia were screened out by serum metabolomics, and the metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism, and nicotinate and nicotinamide metabolism were obtained. A total of 34 chemical constituents were identified by UHPLC-Q-Exactive-MS/MS, including 24 flavonoids, 2 triterpenoid saponins, 4 alkaloids, 2 triterpenoid acids, and 2 fatty acids. The network pharmacological analysis showed that Ziziphi Spinosae Semen mainly acted on target proteins such as dopamine D2 receptor(DRD2), 5-hydroxytryptamine receptor 1 A(HTR1 A), and alpha-2 A adrenergic receptor(ADRA2 A) in the treatment of insomnia. It was closely related to neuroactive ligand-receptor interaction, serotonergic synapse, and calcium signaling pathway. Magnoflorine, N-nornuciferine, caaverine, oleic acid, palmitic acid, coclaurine, betulinic acid, and ceanothic acid in Ziziphi Spinosae Semen may be potential effective compounds in the treatment of insomnia. This study revealed that Ziziphi Spinosae Semen extract treated insomnia through multiple metabolic pathways and the overall correction of metabolic disorder profile in a multi-component, multi-target, and multi-channel manner. Briefly, this study lays a foundation for further research on the mechanism of Ziziphi Spinosae Semen in treating insomnia and provides support for the development of innovative Chinese drugs for the treatment of insomnia.

In this study, the antioxidant property changes in fermented Ziziphi Spinosae Semen(FZSS) with Poria cocos were analyzed by DPPH, ABTS and FRAP methods. Then the content determination of active ingredients and ~1H nuclear magnetic resonance(~1H-NMR) spectroscopy were also used to investigate the mechanism of FZSS with P. cocos in enhancing the antioxidant activity. The results showed that the content of active ingredients such as total phenols, total saponins and total polysaccharides were significantly increased during the fermentation time. The results of ~1H-NMR metabonomics showed that the contents of amino acids such as leucine, lysine, valine and alanine, nitrogen compounds such as creatine, creatinine, and betaine, and secondary metabolites, for instance, jujuboside A and spinosin were higher after fermentation, and above components showed positive correlation with antioxidant capacity in Pearson correlation analysis. Therefore, it was inferred that the enhancement of antioxidant activity of FZSS may be the result of the joint action of various chemical components. This study preliminarily clarified the mechanism of FZSS in enhancing the antioxidant activity, and provided new research ideas for the product development and utilization of FZSS.

Ziziphi Spinosae Semen is one of the Chinese herbal medicine being susceptible to aflatoxins contamination. To investigate the sources of aflatoxins contamination and toxigenic fungi species on Ziziphi Spinosae Semen,32 samples were collected from multiple steps during the post-harvest processing in this study. Aflatoxins in these samples were determined by immunoaffinity column and HPLC coupled with post-column photochemical derivatization. The dilution-plate method was applied to the fungi isolation. The isolated fungi strains were identified by morphological characterization and molecular approaches. The results showed that aflatoxins were detected in 28 samples from every step during the processing of Ziziphi Spinosae Semen. Three samples were detected with aflatoxin B_1 and 2 samples with both aflatoxin B_1 and total aflatoxin exceeding the limit of Chinese Pharmacopoeia. Especially the samples from the washing step,with the highest detected amounts of AFB_1 and AFs were reached 94. 79,121. 43 μg·kg~(-1),respectively. All 32 samples were contaminated by fungi. The fungal counts on the newly harvested samples were 2. 20 × 10~2 CFU·g~(-1). Moreover,it increased as tphreocessing progresses,and achieved 1. 16×10~6 CFU·g~(-1) after washing. A total of 321 isolates were identified to 17 genera. Aspergillus flavus was the main source of aflatoxins during the processing and storage of Ziziphi Spinosae Semen. One isolate of A. flavus was confirmed producing AFB_1 and AFB_2. The fungal count was significantly increased by composting,and Aspergillus was the predominant genus after shell breaking. The contamination level of aflatoxins was increased by composting and washing.

Quantitative nuclear magnetic resonance (qNMR) is a well-established method adopted by international pharmacopoeia for quantitative and purity analyses. Emodin is a type of anthraquinone, well known as the main active component of Fabaceae, Polygonaceae and Rhamnaceae. Purity analysis of emodin is usually performed by using the high-performance liquid chromatography (HPLC)-UV method. However, it cannot detect impurities such as salts, volatile matter, and trace elements. Using the qNMR method, it is possible to determine the compound content as well as the nature of the impurities. Several experimental parameters were optimized for the quantification, such as relaxation delay, spectral width, number of scans, temperature, pulse width, and acquisition time. The method was validated, and the results of the qNMR method were compared with those obtained by the HPLC and mass balance analysis methods. The qNMR method is specific, rapid, simple, and therefore, a valuable and reliable method for the purity analysis of emodin.

This study aimed to analyze the residues of aflatoxin B_1( AFB_1) in Ziziphi Spinosae Semen from different producing areas and to assess the health risk of aflatoxin B_1 residue based on the obtained data. A total of 72 samples of Ziziphi Spinosae Semen from different areas were detected by IAC-HPLC-FLD. Based on the data of AFB_1 pollution,a probabilistic assessment model with Monte Carlo simulation was developed. Then,the risk assessment of AFB_1 exposure by Ziziphi Spinosae Semen intake was carried out by MOE( margin of exposure). The results showed that 32 out of 72 of samples( 44. 4%) were found to be contaminated with AFB_1,and the average and maximum concentration of AFB_1 in samples was 5. 42 μg·kg~(-1) and 55. 09 μg·kg~(-1),respectively. After health risk assessment,the average and 97. 5%( 90% confidence interval) exposure level of daily exposure of AFB_1 by Ziziphi Spinosae Semen intake were 0. 008 6( 0. 008 1-0. 009 2) and 0. 057 3( 0. 053 2-0. 061 4) μg·kg~(-1)·d~(-1),respectively. The results showed common use of Ziziphi Spinosae Semen had low level of risk associated with AFB_1. However,the high consumption of Ziziphi Spinosae Semen showed a higher risk than common intake,requiring attention. This study laid a foundation for clinical safe prescription of Ziziphi Spinosae Semen.
