This study was aimed to observe effects of Albizia Julibrissin Flower Total Flavonoids (AJFTF) on the learning and memory abilities and plasma monoamine neurotransmitters 5-HT and NE content of depression model rats . A total of 90 SD rats were randomly divided into the normal group , model group , western medicine group ( Venlafaxine Hydrochloride 0 . 0125 g?kg-1 ) and high , middle and low dosage groups of AJFTF ( equivalent to the crude drug of 10 , 5 , 2 . 5 g?kg-1 ) . Depression model rats were induced by solitary cultiva-tion and chronic unpredictable stress . The learning and memory abilities of model rats were evaluated with the Morris water maze . And the plasma contents of 5-HT and NE were determined by enzyme-linked immunosor-bent assay ( ELISA ) . The results showed that AJFTF ( administered with high , middle and low dosage for 21 days ) significantly shortened the incubation period of the Morris water maze positioning and navigation ( P <0 . 05 or P < 0 . 01 ) , and increased the times of crossing the platform in space exploration ( P < 0 . 05 or P <0 . 01 ) . There was a certain dose-effect relationship . The AJFTF ( high , middle and low dosage ) increased the plasma contents of 5-HT and NE ( P < 0 . 05 ) . It was concluded that AJFTF can improve learning and memory abilities of depression model rats which indicates that AJFTF have potential antidepressant effects . Its action mechanism may be related to increase plasma monoamine neurotransmitter content of 5-HT and NE .

AIM: To establish the HPLC-FPC of Yinhua Mangguo extract(Flos lonicerae japonicae,Folium Mangiferae,Pericarpium Citri reticulate,etc.). METHODS: The gradient elution was adopted with acetonitrile,methanol and 0.05% phosphoric acid as a mobile phase.The detection wavelength was at 238 nm. RESULTS: The components of Yinhua Mangguo extract were well separated on HPLC,and the HPLC-FPC of 10 batches of samples was established.The results showed that this method had a good repeatability,and the 12 common peaks had an exclusive properties. CONCLUSION: The method developed can evaluate the quality of Yinhua Mangguo extract.

Taxillus chinensis,belonging to hemiparasitic herbal medicine and featuring its wild host range,is used for relief from rheumatic conditions,reinforcement of liver and kidney,strengthening of tendon and bone,and prevention of abortion.It showed that host trees presented significant impacts on the quality of Taxillus chinensis in the modern researches.In this study,both domestic and foreign published articles over Taxillus chinensis from various host trees were reviewed to summarized its herbalogy,chemical constituents,toxicity,and pharmacological action.In regard to the influences on the quality of medicinal materials,ideas and references for the quality control of Taxillus chinensis were provided by analyzing the quality of Taxillus chinensis impacted by hosts.
