ABSTRACT

Objective:The molecular connectivity index method and total statistical moment method were used to control the quality of traditional Chinese medicine (TCM), and the stability and consistency of volatile components of Lonicerae Japonicae Flos and Lonicerae Flos were clarified. Method:Volatile oils in Lonicerae Japonicae Flos and Lonicerae Flos from different producing areas was extracted for GC-MS determination with electron bombardment ion source, ion source temperature of 230 ℃, and detection range of m/z 35-650. Then National Institute of Standards and Technology (NIST) 05 and ChemicalBook database were used for qualitative analysis of these volatile components, the peak area normalization method was used for quantitative analysis, and the total statistical moment parameters and the zero-order, first-order, second-order, third-order molecular connectivity indexes of the components were calculated. Result:Number of peaks (RSD were 28.5%, 33.4%, respectively), total zero-order moments (RSD were 55.5%, 128.9%, respectively) and total second-order moments (RSD were 15.3%, 21.5%, respectively) of 10 batches of Lonicerae Japonicae Flos and Lonicerae Flos were unstable, indicating that the types and contents of volatile components fluctuated sharply, but the total first-order moments (RSD were 7.5%, 8.8%, respectively) and the zero-order, first-order, second-order and third-order molecular connectivity indexes (RSD ranged from 8.1% to 10.3% and 4.2% to 5.5%, respectively) were relatively stable, indicating that the overall "imprinting template" of the components was similar. Statistical analysis of each parameter found that there were no significant differences in the number of peaks, total first-order moments and zero-order, first-order, second-order, third-order molecular connectivity indexes between volatile oils from Lonicerae Japonicae Flos and Lonicerae Flos. Conclusion:Under the guidance of supramolecular gas evolution "imprinting template" theory, the molecular connectivity index method and total statistical moment parameters are used to jointly characterize the "imprinting template" of TCM components in vitro, which can control the stability and consistency of TCM quality.

ABSTRACT

Based on the special influence of supramolecular chemistry on the four-character theory of Chinese materia medica (CMM) proposed in the early stage of this laboratory, this paper further analyzes the historical evolution and research situation of CMM lifting and lowering, and uses the supramolecular “imprint template” theory to analyze the “lifting and sinking” of CMM, and proposes evaluation method of CMM floating and sinking. The human body and CMM are “imprinted templates” of the aggregation of imprinting function, under the effect of the “imprinting template”, different types of Chinese native medicine ingredient targets with human targets through “lock-and-key” relationship in non covalent bond, the role of CMM object supramolecular by key can correct human body supramolecular in the processes of self-recognition, self-organization, self-assembly, self-replication when the fever, disorder of qi occurs. The human body has the ability to resist the invasion of external diseases and pathogens, which depends on the normal “rise and fall” of human qi; CMM has the property of floating and sinking, and can eliminate diseases. It depends on its adjustment of qi disorder of human body, or compliance with qi and removing pathogens to enhance the ability of immunity. Based on this, on the basis of analyzing the pharmacological effects of the rise and fall of CMM, the material basis of the lifting and lowering of CMM was explored, and the evaluation method of the lifting and lowering of traditional Chinese medicine was established. The supramolecular “imprinting template” theory is used to analyze the lifting and lowering of CMM, revealing its scientific connotation and promoting the continuous innovation of CMM pharmacology theory.

ABSTRACT

Research and development of classical prescription of Chinese medicine has become one of the hot spots in the research of traditional Chinese medicine (TCM), and the successful development of the primary standard is crucial to the application of the classical prescription of Chinese medicine. Primary standard of classical prescription is not only the benchmark to measure the quality of preparation of classical prescription, but also the material basis of whole prescription. The development and quality control mode of single component of western medicine is not suitable for the development of TCM preparation with integral medicinal function. Thus, it is very urgent to develop an exclusive research and development model for TCM. In order to break through the quality control technology of primary standard of classical prescription, and comprehensively and accurately elucidate the transmission rule of the component group value of medicinal materials-decoction pieces-primary standard of classical prescription with the present modern science and technology, the genetic polymorphism of TCM, extraction kinetics, total quantum statistical moment (similarity) method of fingerprint and supramolecular imprinting template were combined and applied to the development of primary standard of classical prescription. In this way, the development and quality control of TCM will be realized in a real sense and the development of classical prescription of Chinese medicine will be accelerated and promoted.
