RESUMO

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.

RESUMO

Soil and Uncaria rhynchophylla in different functional areas were selected for the study,the content of heavy metals such as As, Cd, Cu, Cr, Pb, and Hg in soil and U. rhynchophylla was discussed, the characteristics of their accumulation in the U.rhynchophylla was analyzed, the contamination levels of heavy metals in soil in different functional areas was evaluated. The results showed that content of Cu, As, Pb and Cr in soil was being cropland>woodland>wasteland, content of Cd was being woodland>cropland>wasteland, content of Hg was being cropland>woodland>wasteland. According to quality standard of soil environment, soil Cd in woodland, cropland and wasteland all exceeded the state-level standards, soil Cd in woodland exceeded the secondary standard, soil Hg in cropland and wasteland all exceeded the state-level standards. According to technical conditions of green food producing area, soil Cd in woodland exceeded the limit value of standard. According to Green Trade Standards of Importing Exporting Medicinal Plants Preparations,the content of heavy metals of U.rhynchophylla in cropland,woodland and wasteland were correspond to the specification. From the single factor pollution index, the soil in woodland was polluted by Cd. From the comprehensive pollution index, the soils in different functional areas were not contaminated by heavy metals. The enrichment coefficient of heavy metals such as As, Cu, Cr, and Pb in hook of U.rhynchophylla was being wasteland>woodland>cropland, the enrichment coefficient of Cu in hook of U. rhynchophylla in wasteland was more than 1. Except Cu, the enrichment coefficient of other heavy metals was low.
