Abstract: This article was aimed to study" An-shen" drug substances of semen ziziphi spinosae and the relationship between index component distribution in vivo and meridian tropism. Intragastric administration of thyroid tablet suspension at the dose of 160 mg·kg-1 was given for 13 days for the establishment of yin deficiency rat model. Elevated plus maze test (EPM) was combined with light/dark box test to evaluate the effect of semen ziziphi spinosae on anxiety behavior among yin deficiency rats. The yin deficiency anxiety model rats’ eyeballs were picked for blood at 10, 20, 30, 40, 60, 90, 120, 240 min after intragastric administration of semen ziziphi spinosae decoction. The rats were sacrificed for the collecting of heart, liver, spleen, lungs, kidneys, stomach, brain, large intestine and small intestine and other tissues. HPLC-PDA-ELSD was combined to detect concentrations of spinosin, jujuboside A and jujuboside B in different tissues of rats. Related pharmacokinetic parameters were achieved after processing detected data with DAS 2.0 software. The results showed that compared with the yin deficiency group, semen ziziphi spinosae significantly reduced the rats’ abnormal increased food-intake (P < 0.01) and water intake (P < 0.01) within 24 hours; significantly increased the body weight difference before and after treatment (P < 0.01); significantly reduced the kidney coefficient (P < 0.01) and adrenal gland coefficient (P < 0.01); significantly reduced the value of T3 (P < 0.01) and T4 (P < 0.05); significantly increased the value of TSH (P < 0.01). It showed that semen ziziphi spinosae can obviously improve yin deficiency symptoms. It significantly increased the number of open arms entering percentage (P < 0.01), the open arms holding percentage (P < 0.01), and the box through times in light/dark box test (P < 0.01). It showed obvious anti-anxiety effects. The index component distribution in vivo results showed that spinosin and jujuboside A were widely distributed in the heart, liver, spleen, lungs, kidneys, stomach, brain, large intestine, small intestine and other tissues through blood circulation. Jujuboside B was distributed in the blood, stomach, large intestine and small intestine through blood circulation. The order of average concentration of spinosin among tissues was small intestine > stomach > liver > brain > large intestine > spleen > lungs > heart > kidneys. The order of AUC0-t in tissues was small intestine > stomach > liver > large intestine > spleen > brain > heart > kidneys > lungs. The order of average concentration of jujuboside A among tissues was lungs > large intestine > heart > spleen > liver > kidneys > small intestine > stomach > brain. The order of AUC0-t in tissues was lungs > spleen > liver > heart > large intestine > brain > stomach > kidneys > small intestine. The order of average concentration of jujuboside B among tissues was large intestine > small intestine > stomach. The order of AUC0-t in tissues was large intestine > small intestine > stomach. It was concluded that semen ziziphi spinosae can obviously improve yin deficiency symptoms with good anti-anxiety effects. Spinosin and jujuboside A in semen ziziphi spinosae were the drug substances of" An-shen" effect. They were also the material basis of sweet and sour taste. The spinosin and jujuboside A distribution in vivo of yin deficiency anxiety model rats were close to the meridian tropism of semen ziziphi spinosae.
