High-speed liquid chromatographic analysis of acyl esters of 4-methylumbelliferone: High-speed liquid chromatographic analysis of acyl esters of 4-methylumbelliferone. Akada, Yoshinobu; Yamada, Kazushi; Kondo, Tatsuhito; Tanase, Yaichiro (Fac. Pharm. Sci., Tokushima Univ. Arts Sci., Tokushima, Japan). Yakugaku Zasshi, 98(2), 223-5 (Japanese) 1978. CODEN: YKKZAJ.

DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Section cross-reference(s): 27 Acetyl [2747-05-9], propionyl [3361-13-5], butyryl [17695-46-4], isobutyryl [66185-67-9], valeryl [6335-35-9], isovaleryl [66185-68-0], pivaloyl [66185-69-1], caproyl [17695-47-5], enanthoyl [18319-92-1], caprylyl [20671-66-3], pelargonoyl [18319-93-2], caprinoyl [66185-70-4], lauroyl [66185-71-5], palmitoyl [17695-48-6], benzoyl [66185-72-6], and myristoyl [66185-73-7] esters of 4-methylumbelliferone (I) were synthesized and a method was developed for the detn. of these esters by the use of high-speed liq. chromatog. Sepn. was achieved by using a 1-m column of Permaphase ODS, using a gradient from H2O to MeOH as an eluant. Satisfactory sepn. was obtained for 12 normal aliph. acyl esters of I. Accuracy was about ±2%.
