The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

To establish a multi-pretreatment method for the determination of aflatoxin B1, B2, G1, G2 in Chinese patent medicines, aflatoxins were analyzed by high performance liquid chromatography-fluorescence detector with post-column derivatization, after the multi-pretreatment of samples. The results showed that after the samples extracted with MeOH-H2O, dehydrated by anhydrous magnesium sulphate and sodium chloride, and finally purified by neutral alumina, the impurity interference of different sources in Chinese patent medicines matrix can be effectively removed, and the main peak can be nicely separated from the impurity peak. The detection limits were 0.25, 0.25, 0.50, 0.25 μg x L(-1) for AFB1, AFB2, AFG1, AFG2, respectively. The quantification limits were 1.00, 0.50, 1.00, 0.50 μg x L(-1), respectively. Aflatoxin B1, G1 showed a good linear relationship at a range of 1.0-50 μg x L(-1), aflatoxin B2, G2 at a range of 0.5-12.5 μg x L(-1) (R2 > 0.99). The average recovery was 80.40% - 108.6%. The present method is simple, reproducible with the reasonable recoveries and can be applied for the determination of aflatoxins in Chinese patent medicines.
