ABSTRACT
.Aim To establish the evaluation methods of the med¬icine nature of ginsenosides by eorrelation analysis between med¬icine nature and ginsenoside contents in five Panax herbs with different medicine nature and the measurement of their effects on Na + /K + -ATPase activities.Methods 'Hie contents of ginsen¬osides in Sanqi, red ginseng , ginseng , American ginseng and ginseng leaves in the existing literature were eolleeted.and the medicinal nature was assigned by vector methods.rI1ie medicine nature of ginsenosides and the contribution of ginsenoside to the medicine nature were evaluated through bivariate correlation a- nalysis and grey eorrelation degree respectively.'Hie effects of ginsenosides on the Na+ /K +-ATPase activities of L02 eells and in pig eerebral cortex were measured to evaluate the medicine na¬ture of ginsenosides.Results Correlation results indicated that the order of correlation coefficients of ginsenosides to the warm and hot medicine nature was Rf > R1 > Rg3 > Rg2 > Rbl > Ro, while the order of correlation coefficients of ginsenosides to the eool and eold medicine nature was Rb2 > Re > Rd > Fll.Grey eorrelation degree analysis showed that the contribution of ginsen¬oside to the medicine nature was F11 > Re > Kg2 > Rd > Rb2 >Rbl > Rgl > Rc > Rg3 > R1 > Rf > Ro.The effects of ginsen- osides on Na +/K +-ATPase activities showed that the substance basis of the warm medicine nature was ginsenoside Rbl, Rb3, Rc, Rf, Rg2, Rgl, Rhl, Rg3, R1 and Ro, which increased the activity of Na + /K + -ATPase.While the cold and cool medi- cine nature were ginsenoside Rh2, Rd, Rh2, Re and oleanolic acid, which inhibited the activity of Na+/K
ABSTRACT
Objective:To investigate the ecological environment and associated plants of mountain cultivated Panax ginseng were investigated in Xifeng county,Kuandian Manchu autonomous county and Huanren Manchu autonomous county of Liaoning province,in order to provided suggestions on the development of the mountain cultivated P. ginseng in these areas and necessary reference materials for the analysis of ecological suitability of mountain cultivated P. ginseng. Method:The field survey was conducted through sample plot survey in the survey pattern ofbased on representative area-sample plot-quadrat,literature review and data collation, were conducted to record indicators, calculate relevant parameters and make summary. Result:The associated plants were investigated based on 42 samples of mountain cultivated ginseng collected. A total of 95 plant species were identified. The correlation analysis was made on the six main species with an occurrence frequency of higher than 33%, and they were all positively correlated. Asarum heterotropoides var. mandshuricum was the strongest,which was followed by Schisandra chinensis, and Tilia tuan was the strongest in the arbor layer. The survey also found many problems in these areas,such as fewer large-scale planting bases, more scattered households,mixed germplasms,irregular planting techniques,simple planting mode and less sources of economic income generation. Conclusion:Xifeng county,Kuandian county and Huanren county of Liaoning province boast a superior ecological environment and abundant resources of mountain cultivated P. ginseng. The survey gets the whole picture of the ecological environment and associated plants of mountain cultivated P. ginseng in representative areas of Liaoning province,so as to provide the basis for the further development of mountain cultivated P. ginseng cultivation industry and the promotion of mountain cultivated Panax ginseng economy.
ABSTRACT
Recent studies have revealed that the property of drug is mainly associated with the body's substance and energy metabolism. The present study aimed to evaluate the drug property of Poria, called Fuling (FL) in traditional Chinese medicine (TCM), in terms of its effects on the substance and energy metabolism in rat models of cold-deficiency and heat-deficiency syndromes, compared with Aconiti Lateralis Radix Praeparaia, called Fuzi (FZ) in TCM, with hot property, and Anemarrhenae Rhizoma, called Zhimu (ZM) in TCM, with cold property, as reference drugs, respectively. The appearance score, toe and rectal temperatures of the animals treated were assessed at different time points. Several indices in vivo correlated with substance and energy metabolism (glucokinas, phosphoglycerate kinase, cytochrome c reductase, cytochrome c oxydase, and Na-K-ATPase), endocrine system (triiodothyronine, thyroxine, and 17-hydroxycorticosteroid), nervous system (acetylcholin esterase), and cyclic nucleotide system were determined. The changes in appearance score and indices in vivo suggested the successful establishment of cold-deficiency and heat-deficiency syndrome models. FZ reversed the decreased levels of indices (substance and energy metabolism and endocrine system) and alleviated the syndrome of cold-deficiency model, and ZM showed obviously therapeutic effect on heat-deficiency syndrome (appearance score, substance and energy metabolism, and endocrine system). FL could alleviate cold-deficiency syndrome and raise the decreased levels of glucokinas, phosphoglycerate kinase, cytochrome c reductase and triiodothyronine in cold-deficiency model, but had no significant effect on heat-deficiency syndrome. Drug property of FL was inferred as trending to "flat and warm", which still need further study. It was advisable to adopt both cold-deficiency and heat-deficiency models to study the drugs with "flat" property.

Because of the rapid action and high bioavailability, traditional Chinese medicine injections (TCMIs) had been widely used in clinical critical field. In recent years, with the increasing reports of clinical adverse reaction, more and more attention was paid to them, and acute allergic reaction was the main adverse reaction. Acute allergic reaction included type-I anaphylaxis reaction and anaphylactoid reaction, the latter had been found in a variety of TCMIs and accounted for 77% of adverse reaction. But the mechanism of anaphylactoid reaction was not completely understood, the standard animal model for TCMIs was not established, and the technical guidance for anaphylactoid reaction was not formulated. Thus the three aspects included mechanism, evaluation index and evaluation methods of TCMIs for anaphylactoid were reviewed. Five ways including direct stimulating pathway, complement pathway, coagulation pathway, kallikrein-kinin pathway and acute allergic pathway were the main mechanism of anaphylactoid reaction; whole animal model and cell model were the main evaluation methods; the occurrence index and effect index were reviewed for the evaluation index analysis.

With the combined applications of steam distillation, water extraction and alcohol precipitation, liquid-liquid extraction and column chromatography over macroporous resin, a splitted-fractions method of the chemical constituents of Poria cocos was established. The unoverlapping property of the fractions of P. cocos was qualitatively analysed by using principal component analysis and cluster analysis. With angle cosine, squared euclidean distance and the overlapping analysis of peak area of crude herbs, the unoverlapping property of the fractions of P. cocos was half-quantitatively analysed. The chemical components of P. cocos was divided into the fractions of polysaccharide, petroleum ether, ethyl acetate, alcohol eluate from macroporous resin and water eluate from macroporous resin. Non similarity degree among each chemical fraction was above 80% and main chemical components were identified. The established method for splitting fractions of P. cocos has good stability and repeatability and all chemical components in P. cocos could be completely divided into six fractions. It is the first time that the author half-quantitatively analyse the unoverlapping property of the chemical fractions of P. cocos.
