Si-Mo-Tang（SMT） oral liquid preparation, a traditional Chinese medicine, was prepared from four crude herbal drugs, Fructus Aurantii Submaturus, Radix Aucklandiae, Semen Arecae and Radix Linderae Aggregatae. A combinative method using HPLC fingerprint and quantitative analysis was developed and validated for quality consistency evaluation of SMT. Individual HPLC chromatograms were evaluated against the mean chromatogram generated via a similarity evaluation computer program. Data from chromatographic fingerprints were also processed with principal component analysis（PCA） and hierarchical cluster analysis（HCA）. Additionally, six components （naringin, isonaringin, hesperidin, neohesperidin, norisoboldine and potassium sorbate） in SMT were simultaneously determined to interpret the quality consistency. For fingerprint analysis, 20 peaks were selected as the characteristic peaks to evaluate the similarities of 26 SMT collected from different manufacturers. Among the 20 characteristic peaks, 10 peaks were assigned to be naringin, hesperidin, neohesperidin, isonaringin, neoeriocitrin, tangeretin, nobiletin, norisoboldine, 5-（ethoxymethyl）furan-2-carbaldehyde and potassium sorbate, respectively. The results of similarity analysis, PCA and HCA, indicate that the samples from different manufacturers were consistent with each other in composition. The results from the quantitative data show that the contents of six compounds were significantly different in SMT oral liquid preparations from different manufacturers. The combinative method of chromatographic fingerprint with quantitative analysis developed here offered an efficient way for the quality consistency evaluation of the traditional Chinese medicine SMT.

第九届全国环境催化与环境材料学术会议——助力两型社会快速发展的环境催化与环境材料

作者： Xiaomei wang Jianhan huang You-Nian liu Department of Bioengineering and Environmental Science Changsha University college of chemistry and chemical engineering Central South University

The porogens used in the polymerization play important roles in the chemical structure, pore structure and adsorption performance for the polar-modified post-cross-linked resins. A series of novel polar-modified post-cross-linked resins were prepared using different mass percentage of toluene and 3-methyl-1-butanol as the mixed porogens(Scheme 1), and the results indicated that the resins using a higher mass percentage of toluene in the mixed porogens possessed a higher content of pendent vinyl groups, the greater Brunauer-Emmett-Teller(BET) surface area and t-plot micropore surface area. What’s more, the Friedel-Crafts alkylation reaction induced a higher increment of the BET surface area and t-plot micropore surface area. The resin using 50%(w/w) of toluene and 50%(w/w) of 3-methyl-1-butanol in the mixed porogens held the largest equilibrium capacity to phenol among the four considered resins. The equilibrium data was well characterized by the Freundlich model and the isosteric enthalpy decreased strongly with increasing of the fractional loading. The resin using a lower mass percentage of toluene in the mixed porogens required less time to reach equilibrium because of its less micropores and the minor diffusion resistance in the pores. p(GMA-co-DVB)-22-pc exhibited a dynamic saturated capacity of 55.4 mg/m L wet resin at an initial concentration of 1250 mg/L and a flow rate of 1.4 m L/min, and it could be completely regenerated by 0.001 mol/L of sodium hydroxide(w/v) and 80% of ethanol(v/v).
