Comparison of the sedative and hypnotic effects of flavonoids, saponins, and polysaccharides extracted from Semen Ziziphus jujube.:Nat Prod Res. 2007 Apr;21(4):310-20.Jiang JG, Huang XJ, Chen J, Lin QS.College of Food, South China University of Technology, Guangzhou 510640, China. jgjiang@scut.edu.cn
Semen Ziziphus jujube (SZJ), the seeds of Ziziphus jujuba Mill. var. spinosa, is a kind of traditional Chinese medicine used for its action on insomnia. In order to analyze the effective component, we investigated and compared the sedative and hypnotic effects of three kinds of compounds, flavonoids, saponins, and polysaccharides. Flavonoids, saponins, and polysaccharides were extracted from SZJ and orally administered to mice separately at 17 g kg(-1) per day for certain days before animal tests. Spontaneous motility and coordinated movement tests were used to observe the effects of the three kinds of compounds on the mouse behavior, and sodium barbital-induced sleeping time of mouse were tested to analyze the effects of the three kinds of compounds on the sleep of mouse. Results show that flavonoids and saponins caused a significant reduction of walking time and coordinated movement ability of mouse, significantly prolonged its sleeping time at 40 mg kg(-1), ip, subthreshold dose and increased the sleeping number of animals at 50 mg kg(-1), ip, superthreshold dose induced by coeliac injection of sodium barbital. Polysaccharides did not show any significance in all animal tests. Comparative analysis showed that saponins had a more effective sedative and hypnotic function than that of flavonoids, polysaccharides did not show a sedative and hypnotic effect.
Simultaneous determination of saponins and fatty acids in Ziziphus jujuba (Suanzaoren) by high performance liquid chromatography-evaporative light scattering detection and pressurized liquid extraction.:J Chromatogr A. 2006 Mar 10;1108(2):188-94.

The seed of Ziziphus jujube Mill. var. spinosa (Bunge) Hu ex H. F. Chou, Suanzaoren in Chinese, is one of commonly used Chinese medicines. Saponins and fatty oil contains several fatty acids in Suanzaoren are responsible for its therapeutic activities. In this study, a new HPLC coupled with evaporative light scattering detection (ELSD) and pressurized liquid extraction (PLE) method was developed for the simultaneous quantitative determination of 11 major components of 2 saponins and 9 fatty acids, namely jujuboside A, jujuboside B, lauric acid, myristic acid, palmitic acid, palmitoleic acid, stearic acid, oleic acid, linoleic acid, arachidic acid and docosanoic acid in Suanzaoren. Simultaneous separation of these eleven compounds was achieved on a C18 analytical column. The mobile phase consisted of (A) 0.1% aqueous acetic acid and (B) methanol with 0.1% acetic acid using a gradient elution. The drift tube temperature of ELSD was set at 75 degrees C, and nitrogen flow-rate was 1.8l/min. All calibration curves showed good linearity (r(2)>0.9955) within test ranges. This method showed good reproducibility for the quantification of these eleven components in Suanzaoren with intra- and inter-day variations of less than 3.41 and 4.37%, respectively. The validated method was successfully applied to quantify 11 investigated components in nine commercial samples of Suanzaoren.
Protection of NMDA-induced neuronal cell damage by methanol extract of zizyphi spinosi semen in cultured rat cerebellar granule cells.:J Ethnopharmacol. 2004 Nov;95(1):39-45.Park JH, Lee HJ, Koh SB, Ban JY, Seong YH.College of Veterinary Medicine and Research Institute of Veterinary Medicine, Chungbuk National University, Cheongju, Chungbuk 361-763, South Korea.
Zizypus is one of the herbs widely used in Korea and China due to the CNS calming effect. The present study aims to investigate the effect of the methanol extract of Zizyphi Spinosi Semen (ZSS), the seeds of Zizyphus jujuba Mill var. spinosa, on N-methyl-D-aspartate (NMDA)-induced neurotoxicity in cultured rat cerebellar granule neuron. ZSS, over a concentration range of 0.05-5 microg/ml, inhibited NMDA (1 mM)-induced neuronal cell death, which was measured by a trypan blue exclusion test and a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide (MTT) assay. ZSS (0.5 microg/ml) inhibited glutamate release into medium induced by NMDA (1mM), which was measured by HPLC. Pretreatment of ZSS (0.5 microg/ml) inhibited NMDA (1mM)-induced elevation of cytosolic calcium concentration ([Ca(2+)](c)), which was measured by a fluorescent dye, Fura 2-AM, and generation of reactive oxygen species (ROS). These results suggest that ZSS prevents NMDA-induced neuronal cell damage in vitro.

Activity-guided fractionation of the seeds of Ziziphus jujuba using a cyclooxygenase-2 inhibitory assay.:
Bioactivity-guided fractionation of petroleum ether- and EtOAc-soluble extracts of the seeds of Ziziphus jujuba using a cyclooxygenase-2 assay as a monitor indicated that the triglyceride, 1,3-di-O-[9(Z)-octadecenoyl]-2-O-[9(Z),12(Z)-octadecadienoyl]glycerol (3), and a fatty acid mixture of linoleic, oleic and stearic acids, were the major active components. A new pentacyclic lupane-type triterpene derivative, 3-O-[9(Z)-octadecenoyl]betulinic acid (1), and betulinic acid (2) were also isolated and identified. All isolates as well as pure linoleic, oleic and stearic acids were evaluated for their inhibitory effects against both cyclooxygenases-1 (COX-1) and -2 (COX-2).
Anti-complementary activity of triterpenoides from fruits of Zizyphus jujuba.:
In order to determine on the anti-complement activity of triterpenes, following eleven triterpenoides were isolated from the fruits of the Zizyphus jujuba MILL: ceanothane-type triterpenes: colubrinic acid (1), zizyberenalic acid (11); lupane-type triterpenes: alphitolic acid (2), 3-O-cis-p-coumaroyl alphitolic acid (3), 3-O-trans-p-coumaroyl alphitolic acid (4), betulinic acid (7), betulonic acid (9); and oleanane-type triterpenes: 3-O-cis-p-coumaroyl maslinic acid (5), 3-O-trans-p-coumaroyl maslinic acid (6), oleanolic acid (8), oleanonic acid (10). These compounds were examined for their anti-complement activity against the classical pathway of the complement system. Among them, compounds 5, 6, and 8 exhibited significant anti-complement activity with IC(50) values of 101.4, 143.9, and 163.4 microM, respectively, whereas the ceanothane-type and the lupane-type triterpenes were inactive. This suggests that the oleanane-structure plays an important role in inhibiting the hemolytic activity of human serum against erythrocytes.

The mobile phase consisted of acetonitrile-water-acetic acid (15:85:1) at a flow rate of 0.7 mL.min-1. The UV detection wavelength was set at 334 nm. RESULTS: The calibration curve was shown to be linear over the range from 18.1 to 903.5 micrograms.L-1 (r2 > or = 0.995). Mean recovery was 94.5%. Within-day and between-day precisions RSD were less than 9.0%. The limit of quantitation was 18.1 micrograms.L-1. The plasma spinosin was stable at -20 degrees C. CONCLUSION: The simple, sensitive and accurate HPLC method developed has been applied to determine the pharmacokinetics of spinosin in rat plasma after having taken Suanzaoren extract at a single dose.
Inhibitory effect of jujuboside A on glutamate-mediated excitatory signal pathway in hippocampus.:
Jujuboside A (JuA) is a main component of jujubogenin extracted from the seed of Ziziphus jujuba Mill var spinosa (Bunge) Hu ex H F Chou (Ziziphus), which is widely used in Chinese traditional medicine for the treatment of insomnia and anxiety. Previously, we reported the inhibitory effects of JuA on hippocampal formation in vivo and in vitro, the present study was carried out to examine the effects of JuA on glutamate (Glu)-mediated excitatory signal pathway in hippocampus. Microdialysis coupled with high-performance liquid chromatography (HPLC) was used to monitor the changes of Glu levels in the hippocampus induced by penicillin sodium, or a mixture of penicillin sodium and JuA. The results showed that penicillin increased the hippocampal Glu concentration (p < 0.01) and a high dose of JuA (0.1 g/L) significantly blocked penicillin-induced Glu release (p < 0.05). Moreover, the effect of JuA on intracellular Ca2+ changes after the stimulation by Glu was studied in cultured hippocampal neurons with confocal laser scanning microscope (CLSM). It was found that Glu (0.5 mM) induced an intracellular [Ca2+]i increase (p < 0.01), and JuA significantly inhibited the Glu-induced Ca2+ increase. The calmodulin (CaM) antagonist trifluoperazine (TFP) showed a similar inhibitory effect as JuA. These observations suggested that JuA has inhibitory effects on Glu-mediated excitatory signal pathway in hippocampus and probably acts through its anti-calmodulin action.
The inhibitory effects of jujuboside A on rat hippocampus in vivo and in vitro.:
Jujuboside A (JuA) is a glycoside extracted from the seed of Ziziphus jujuba Mill var. spinosa (Bunge) Hu ex H F Chou, a Chinese herbal medicine, which has long been known as a sedative-hypnotic drug. The present study used the method of intracerebroventricular (i.c.v.) JuA in vivo to detect the effect of JuA on paired-pulse responses of dentate gyrus granule cells in urethane-anaesthetized rats, and the method of hippocampal slice bathing in JuA in vitro to detect the effects of JuA on the responses of CA1 pyramidal cells. The results showed that JuA significantly decreased the slopes of excitatory postsynaptic potential (EPSP) and the amplitudes of population spike (PS) in the first responses of granule cells and significantly decreased EPSP and PS in the responses of CA1 pyramidal cells. The good quantitative correspondence between in vitro and in vivo results indicates that studies using hippocampal formation allow research on the inhibitory effects of JuA in the rat central nervous system (CNS). In conclusion, our study accessed the inhibitory effects of JuA on hippocampal formation in vivo and in vitro, which contributed to the further research on the mechanism of its effects on CNS.
