| 1 | Determining method and conditional factors of electrochemical fingerprint of Chinese traditional medicine显示文摘The thermodynamic systems and kinetic model suitable for the electrochemical token of the compo-nent throng in Chinese traditional medicines have been analyzed. It has been indicated that the damp oscillatory reactions in the non-equilibrium close system and open system without the supplement of dissipative substance have important significance for the throng token and analysis of chemical com-ponents in Chinese traditional medicines. Various factors influencing the electrochemical fingerprint,such as reactant species and their concentrations,electrode types,temperature,stir rate,the kind,dosage and granularity of Chinese traditional medicines,have amply been researched by the B-Z os-cillatory reaction which used malonic acid as a main dissipative substance. In addition,the quantitative information about the chemical components in Chinese traditional medicines has been discussed in detail. The method and its conditions for determining the electrochemical fingerprint used in scientifi-cally distinguishing and evaluating Chinese traditional medicines have successfully been put forward. | ZHANG TaiMingt LIANG YiZeng YUAN Bin DING Feng ZHANG YaPeng WEI ManQiong CHEN Xu | 2007 | Chinese Science Bulletin2007，52，16： | 22 |
| 2 | Application of nonlinear chemical fingerprinting to identification,evaluation and clinical use of Glycyrrhiza显示文摘Nonlinear chemical fingerprinting is a new technique for analyzing traditional Chinese medicines (TCMs). We developed such a method and applied it to Glycyrrhiza, a significant TCM. Nonlinear chemical fingerprints were obtained for Glycyrrhiza from four different production areas, and for 14 other TCMs with similar induction time. The calculation of their similarities was based on similarity system theory. Using intuitive visual comparison of the data and the similarity calculation results, Glycyrrhiza was discriminated from the 14 other TCMs. There was a linear relationship between the content of active TCM components and the induction time. This was used to compare the content of active components in Glycyrrhiza from the four different production areas, and establish an equivalent-dose relationship for these four samples. This method provides a new tool for discrimination and evaluation of Glycyrrhiza, and a dosage reference for clinical application of Glycyrrhiza from the four regions studied. | FANG XuanQi ZHANG TaiMing ZHAO Zhe XIANG FengQin LIANG YiZeng WANG Mei ZHU Rong CHEN Su QIAO JunXi | 2010 | Chinese Science Bulletin2010，55，26： | 20 |
| 3 | Principle, traits and functions of electrochemical fingerprint of Chinese traditional medicine显示文摘In regard to such challenging analysis problems as scientific identification and quality evaluation of Chinese traditional medicine, the electrochemical fingerprint technique of Chinese traditional medi- cine has been researched. The principle, traits, functions, etc., of the electrochemical fingerprint have detailedly been analyzed and discussed by the B-Z oscillatory system using malonic acid as main dissipation substance, characterized by the fact that different influences of different Chinese traditional medicines on the mechanism of the oscillatory reaction cause different changes of the shape of the potential-time curve of the oscillatory system under the conditions of constant tem- perature and pressure. An economical, simple and convenient, easy pushing and effective scientific method for distinguishing and evaluating multifarious Chinese traditional medicines has success- fully been put forward. | ZHANG TaiMing LIANG YiZeng YUAN Bin DING Feng ZHANG YaPeng CHEN WenYan | 2007 | Chinese Science Bulletin2007，52，20： | 16 |
| 4 | Determining method,conditional factors,traits and applications of nonlinear chemical fingerprint by using dissipative components in samples显示文摘The thermodynamic systems and dynamic model suitable for determining the nonlinear chemical fingerprints of samples were analyzed.The results indicated that the damp nonlinear chemical reactions in close systems away from the equilibrium and open systems without the complementarity of the dissipation substances have important significance for the throng characterization and whole content analysis of chemical components in samples.Various factors influencing on nonlinear chemical fingerprint,such as reactant species and their concentrations,electrode types,temperature,stir rate,the sort,dosage and granularity of the sample,etc.were amply researched by a nonlinear chemistry reaction,namely,damp B-Z oscillation which used acetone and glucose as the main dissipative substances.In addition,the quantitative information on the whole of chemical components in samples and the traits and applications of the fingerprint were investigated.The method and its important conditions for determining nonlinear chemistry fingerprint used in distinguishing and evaluating complex samples were successfully put forward. | ZHANG TaiMing ZHAO Zhe FANG XuanQi QIAO JunXi XIANG FengQin ZHU Rong LIANG YiZeng DING Feng | 2012 | Science China Chemistry2012，55，2： | 16 |
| 5 | Principle of nonlinear chemical fingerprint by using dissipative components in samples as well as calculation and evaluation of similarity显示文摘Under the conditions of constant temperature and pressure,different influences of samples with different chemical components on the mechanism of nonlinear chemical reaction will cause different changes of the potential-time relationship curve of the nonlinear chemical reaction system.Using it as the character,and using the B-Z nonlinear chemical system to use acetone and substrates in samples as main dissipative substances qua an example,the principle of nonlinear chemical fingerprint has been researched and discussed in detail.At the same time,the general method for calculating the system similarity about nonlinear chemical fingerprint was also put forward,and similarities of nonlinear chemistry fingerprints of different batches of Guhan Yangshengjing and 18 sorts of other samples were calculated by Euclidean distance,correlation coefficient,included angle cosine and system similarity,at the same time,the various similarities were analyzed.The results showed that,both of correlation coefficient and included angle cosine are unable to be used as the criterion for quantitatively evaluating the similarity of nonlinear chemistry fingerprint;as non-parametric similarity,Euclidean distance can accurately reflect the feature differences in the fingerprints,but as parametric similarity,sometimes,Euclidean distance can not accurately reflect the relative extent of characteristic difference in the nonlinear chemical fingerprints;system similarity can most truthfully reflect the characteristic difference in the nonlinear chemical fingerprints,and is the best evaluating method among the four ones.Therefore,system similarity can be used to quantitatively calculate the similar extent between the nonlinear chemical fingerprints.An economical,simple and convenient,easy pushing and effective method for identifying and evaluating complicated samples has successfully been put forward. | ZHANG TaiMing ZHAO Zhe FANG XuanQi QIAO JunXi XIANG FengQin ZHU Rong LIANG YiZeng DING Feng | 2012 | Science China Chemistry2012，55，2： | 13 |
| 6 | Chemometrics and modernization of traditional Chinese medicine显示文摘Development of chromatographic fingerprinting and its related chemometric methods in the research of quality control of traditional Chinese medicines(TCMs) are discussed. The quality control methods for guarantying the authentication and stability of products and semi-products of TCMs are firstly assessed. The technique based on chromatographic fingerprinting is essentially a kind of high-through put and integral tools to explore the complexity of herbal medicines. In order to further control the comprehensive quality of TCMs,confirmation and identification of their important chemical components are necessary. Some new strategies are proposed to trace the chemical changes of chromatographic fingerprints both in product processing and/or after their administration by modern chromatographic techniques and chemometrics. Combined with systems biology and bioinformatics,it seems possible for one to reveal the working mechanism of TCMs and to further control their intrinsic quality comprehensively. | LIANG YiZeng YI LunZhao XU QingSong | 2008 | Science China Chemistry2008，51，8： | 3 |
