Simple precolumn saponification and esterification with phenacyl reagents for microanalysis of fatty acid in fat and oil by high performance liquid chromatography: Simple precolumn saponification and esterification with phenacyl reagents for microanalysis of fatty acid in fat and oil by high performance liquid chromatography. Kihara, Kazuko; Rokushika, Souji; Hatano, Hiroyuki (Fac. Sci., Kyoto Univ., Kyoto 606, Japan). Bunseki Kagaku, 33(12), 647-52 (Japanese) 1984. CODEN: BNSKAK. ISSN: 0525-1931. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) A simplified sapon. and derivatization procedure for the microanal. of fatty acids in fat and oil involved a miniaturized one-pot reaction, in which fat or oil (0.01~1 mg) was first hydrolyzed with 0.1 M methanolic KOH (0.2 mL) in a sealed vial. After heating at 90° for 10 min, the solvent was removed, and the resulting fatty acid K salts were reacted with phenacyl [50781-28-7], p-bromophenacyl [99-73-0], or 2-naphthacyl bromide [613-54-7] in the presence of 18-Crown-6 in 1 mL of CHCl3. The obtained UV-labeled esters were analyzed by liq. chromatog. on an ODS column. The esters were stable in the reaction mixt. for 3 mo in the dark. The chromatog. response was linear with respect to fatty acid concns. from 5 mM to 5 mM. Com. butterfat constituents were analyzed by the microanal. procedure, and the result in was in good agreement with those obtained by conventional methods.

Silver-modified mobile phase for normal-phase liquid chromatographic determination of prostaglandins and their 5,6-trans isomers in prostaglandin bulk drugs and triacetin solutions: Silver-modified mobile phase for normal-phase liquid chromatographic determination of prostaglandins and their 5,6-trans isomers in prostaglandin bulk drugs and triacetin solutions. Kissinger, L. D.; Robins, R. H. (Upjohn Co., Kalamazoo, MI 49001, USA). J. Chromatogr., 321(2), 353-62 (English) 1985. CODEN: JOCRAM. ISSN: 0021-9673. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Section cross-reference(s): 2 A silver-modified, normal-phase HPLC was developed for prostaglandin bulk drugs and triacetin [102-76-1] solns. AgNO3 present in the mobile phase results in high selectivity for cis/trans isomers with conventional silica columns. Prostaglandins were esterified with a-bromo-2'-acetonaphthone [613-54-7] prior to chromatog. to provide high detectability at 254 nm. For dil. triacetin solns., a sample prepn. scheme based on gravity-flow chromatog. with silica columns was developed to isolate the prostaglandin from triacetin prior to derivatization. The anal. technique was applied to triacetin solns. contg. as little as 10 mg/mL arbaprostil (I) [55028-70-1].
