Thirty nine compounds in the volatile oils of the flowerbuds of Panax quinquefolium L.cultivated in China were isolated and identified with gas chromatography/mass spectre metry. To our great surprise,β-famensene,a sesquiterpene compound of them,alone account for 48.67% of the total volatile oils contents. This experimental result was contrasted with the volatile oils components of the different parts of Panax quinquefolium L.and Panax ginseng,anidentical genus plant,on chemical components and relative quantities.It was discovered that the only one common component is β-famensene in them and it is the highest value in determined relative contents. Above result provides scientific basis for biological synthesis of triterpenoid saponins.

This study was aimed to investigate Baishile Capsule on behavior, memory and expression of SYN I and SYNA in hippocampal CA3 region of depression model rats. SD rats were randomly divided into six groups, which were the control group, depression model group, fluoxetine hydrochloride group, and the Baishile Capsule group (2.88 g·kg-1, 1.44 g·kg-1, 0.72 g·kg-1). The chronic stress depression model rats were established by chronic and mild unpredictable stressors as described in the literature. In the model group, medicine was intragastricly administered once per day and continued for 21 days. In the control group and model group, same volume of distilled water was intragastricly administered. The open-field test, preference for 1% sucrose solution, Morris water maze, and rate of weight were carried out and observed. Immunohistochemistry and in situ hybridization were used in the observation of the expression of SYN I and SYNA in each group of model rats. The results showed that high-dosage Baishile Capsule can significantly increase the horizontal and vertical activities of score after two-week treatment (P< 0.01). The middle-dosage Baishile Capsule can significantly increase the horizontal activity of score after three-week treatment (P< 0.05). The rat's preference for sucrose solution was obviously increased in the high-dosage group after one-week treatment and in the middle-dosage group after three-week treatment (P< 0.01, or P< 0.05). The rate of weight of rats was obviously increased in the high-dosage group after two-week treatment and in the middle-dosage group after three-week treatment (P< 0.01, or P< 0.05). The high-dosage and middle-dosage Baishile Capsule can shorten EL, and significantly increase the number of target quadrant. The high-dosage Baishile Capsule can obviously shorten the target quadrant latency (P< 0.05). Compared with the model group, the immunohistochemistry and in situ hybridization showed high-dosage Baishile can significantly promote the expression of SYN I and SYNA in hippocampal CA3 region; and the middle-dosage group can enhance the expression of SYNA (P < 0.05, or P <0.01). It was concluded that Baishile Capsule can obviously improve the behavior and the expression of SYN I and SYNA in hippocampal CA3 region of depression model rats.

Two p-phenylenediamine (p-PD)-imprinted polymers, P (MAA) and P (AA), were synthesized using methacrylic acid (MAA) and acrylamide(AA) as functional monomer, respectively, in order to prepare molecular recognition material with high selectivity for p-PD and explore the feasibility of methods such as molecular spectrometry and computational approach of quantum chemistry for the selection of functional mono mer with high imprinting efficiency.The molecular recognition properties of the imprinted polymers were evaluated by high performance liquid chromatography.The results indicated that P(AA) exhibited no imprint ing effect for p-PD, while P(MAA) can bind p-PD selectively(k' =3.57), which showed remarkable imprint ing effect (IF=2.95), and p-PD and its analogues o-phenylenediamine and p-aminobenzoic acid can almost realize baseline separation on P (MAA) column in the mobile phase of methanol.Furthermore, we made a comparative study on the interaction of p-PD with MAA and AA by spectroscopic techniques such as UV and fluorometry as well as HF/6-31G~* computational approach.The results demonstrated that the complex of p-PD-MAA was more stable than that of p-PD-AA, which can give a good explanation for the molecular recog nition properties of P (MAA) and P (AA).The study indicated that both molecular spectrometry (UV and fluorometry)and computational approach of quantum chemistry can be employed as efficient means for the selection of efficient functional monomer.The results showed that fluorometry is sensitive and convenient for the choice of functional monomer if the template molecule is fluorescent.

Using a micro-column packed with polyethylenimine aminated glycidyl methacrylatE-grafted-polytetrafluoroethylene fiber made by ourselves as the adsorption material, the adsorption behaviors of Pb and Cd under different conditions were studied by inductively coupled plasma optical emission spectrometry. The conditions for the preconcentration of Pb and Cd such as pH, flow-rate, time and eluent acidity were optimized. The results show that the PTFE-g-GMA-PEI Fiber has excellent adsorption property and high adsorption capacity for Pb2+ and Cd2+. The Enrichment factors for Pb2+ and Cd2+ were 30 and 80, respectively and the detection limits were 3.5 μg/L and 0.15 μg/L, respectively, the relative standard derivations were 1.5% and 0.6%(n=9)respectively. When the single ion concentration was 50 μg/L, the sampling frequency was 9 and 18 times/h, respectively. The method was applied to the simultaneous determination of trace lead and cadmium of several Chinese traditional medicine samples, the standard recovery of samples was 90%-108%.
