摘要

Abstract

The analysis of sucrose esters with long acyl chain by improved high performance liquid chromatographic method with evaporative light scattering detection(HPLC-ELSD) and electrospray ionization mass spectrum(ESI-MS) is investigated.The improved HPLC-ELSD method for the separation and quantitation of commercial and synthesized sucrose esters is described.Samples are analyzed by means of a reversed-phase(RP) HPLC using a Hypersil C8 column(250 mm×4.6 mm

5 μm particle size) with methanol-tetrahydrofuran(volume ratio of 90:10) and water under gradient condition as the mobile phase

in which the flow rate is 1.0 ml·min

-1

and the column temperature is set at 40℃.This procedure provides a complete separation and determination of monoester

diester

triester and higher esters with different acyl chain lengths in each fraction by a single run

in combination with the ESI-MS technology.With this method

it is possible to determine the approximate compositions of mono-to polyesters in one analysis and quantitate pure positional isomers precisely using an external standard method.It is found that the method of ESI-MS coupling with HPLC system for the analysis of sucrose esters is straight forward

rapid and inexpensive

and can be readily applied in synthesis

purification and structure studies.
