“…The commonly used method of FT-IR, named as multi-steps infrared macro-fingerprint method, combines three steps: conventional FT-IR, second derivative spectroscopy, and two-dimensional infrared (2D-IR) correlation spectroscopy [87,88]. Among them, 2D-IR correlation spectroscopy was proposed by Noda in 1986, and then introduced by Sun to the quality control of TCMs [87][88][89]. The main advantages of 2D correlation analysis are: simplification of complex spectra consisting of overlapped peaks, enhancement of spectral resolution by spreading peaks over the second dimension, and providing interaction and dynamic information of functional groups in the system [87].…”

“…They were separated with GC, and the area under the peaks was used for quantitative determination of these markers [1]. The use of those chromatographic methods invariably necessitates the use of some sample preparation procedure that may be tedious, and the chromatographic separation usually takes tens of minutes to hours [2,3]. In addition, chromatographic methodology consumes solvents and/or gases as well as standards for external calibration, spiking, or internal standardization in every determination [4].…”

“…The word "Chinesetraditional-medicine fingerprint" employed in the throng token of chemical components in CTM qua unknown complex system also emerged as the needs of the times, and the important actions of the fingerprints in the identification, evaluation and quality control of CTMs have widely been realized. At present, the fingerprint of CTM has become one of the research hotspots, and there are respectable production reports, including HPLC [2 -7] , GC [8] , TLC [5,6,9] , high speed countercurrent chromatography (HSCC) [7,10,11] , CE [11,12] and infrared spectrum fingerprints [13,14] , etc. However, the research on electrochemical fingerprints of CTMs has not been reported so far.…”

The thermodynamic systems and kinetic model suitable for the electrochemical token of the component 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 components 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 oscillatory 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 scientifically distinguishing and evaluating Chinese traditional medicines have successfully been put forward. electrochemical fingerprint, test method, conditional factor, differentiation of verity and falsity, quality evaluation, Chinese traditional medicineThe phenomena of mixing the false with the genuine and selling the shoddy medicines often take place in the market of Chinese traditional medicine (CTM), which has badly restricted the security to employ CTM and the stabilization of the curative effects, and has also restricted the developments of research and application of CTM. Therefore, none but scientific identification, evaluation and quality control performed to CTM can insure their good quality, validity, security of use, and stabilization of curative effect. Consequently, the research on scientific methods for the identification of verity and falsity, and quality evaluation of CTMs has become a problem vigorously challenging the analysts and pharmic chemists [1] . CTMs are very complex analysis systems whose most effective or active components have not been made sure. Therefore, the identification of verity and falsity, and the quality evaluation of CTMs by only employing the analytical indexes of some chemical components in CTMs are not scientific and precise, and often provide the entrance of the bastardly and low-grade products into the legal market with opportunities. Indeed, the identification and evaluation of CTMs from the results obtained by analyzing chemical components in CTMs one by one through separation, purification, spectrum techniques and other analytical methods are the most reliable methods. However, the methods are not suitable for the identification and evaluation of most CTMs with complex components due to their disadvantages such as high analysis cost, long operation flow, and burdensome workload. The analytical cost and time may be decreased consumedly by the multivariate resolution and calibration techniques of chemometrics,
