| 中文摘要 | a new labeling reagent for carboxylic acids, 2-(2-(anthracen-10-yl)-1h-phenanthro[9,10-d]imidazol-1-yl)ethyl 4-methylbenzenesulfonate (apiets) has been designed and synthesized. it was used to label eight fatty acids (lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, oleic acid, linoleic acid and linolenic acid) and four hydroxy pentacyclic triterpene acids (oleanolic acid, ursolic acid, betulinic acid and maslinic acid), successfully. apiets could easily and quickly label carboxylic acids in the presence of k(2)co(3) catalyst at 85 degrees c for 35 min in n,n-dimethylformamide solvent. the carboxylic acids derivatives were separated on a c(8) reversed-phase column with gradient elution and fluorescence detection at lambda(ex)/lambda(em) = 315/435 nm. identification of these derivatives was carried out by online mass spectrometry with atmospheric pressure chemical ionization in positive ion mode. the detection limits obtained were 13.37-30.26 fmol (signal-to-noise ratio of 3). the proposed method has been applied to the quantification of carboxylic acids in sultana raisin (thompson seedless), hawthorn flake (crataegus pinnatifida bge.), lycium barba rum seed oil and microula sikkimensis seed oil with recoveries over 95.3%. it has been demonstrated that apiets is a prominent labeling reagent for determining carboxylic acids with high performance liquid chromatography.
