High-Performace Liquid Chromatographic Determination of Mono- and Oligosaccharides in Vegetables with Evaporative Light-Scattering Detection and Refractive Index Detection
Two high-performance liquid chromatographic methods are compared for the determination of monoand oligosaccharides in vegetables using an N H 2 column and acetonitrile-water as the mobile phase. One method uses a gradient elution and evaporative light-scattering detection; method precision (relative standard deviation) ranges from 1.09 to 4.44%, and detection limits range from 0.014 to 0.061 mg...
متن کاملDetermination of Propionylbrassinolide and Its Impurities by High-Performance Liquid Chromatography with Evaporative Light Scattering Detection.
The discovery of brassinolide in 1979, a milestone in brassinosteroids research, has sparked great interest of brassinolide analogs (BLs) in agricultural applications. Among these BLs, propionylbrassinolide has captured considerable attention because it shows plant growth regulating activity with an excellent durability. Two impurities of propionylbrassinolide were isolated and purified by semi...
متن کاملDetermination of free and amidated bile acids by high-performance liquid chromatography with evaporative light-scattering mass detection.
A simple reverse phase high-performance liquid chromatographic method for a simultaneous analysis of free, glycine- and taurine-amidated bile acids is described. The resolution of ursodeoxycholic, cholic, chenodeocycholic, deoxycholic, and lithocholic acids, either free or amidated with glycine and taurine, is achieved using a C-18 octadecylsilane column (30 cm length, 4 micron particle size) w...
متن کاملAnalysis of Tocopherols and Phytosterols in Vegetable Oils by HPlC with Evaporative Light - Scattering Detection 1
Methods were developed for the separation, detection, and quantification of tocopherols and phytosterols by high-performance liquid chromatography with an evaporative light-scattering detector. Four tocopherolsa, fJ, y and o-and four phytosterols-campesterol, fJ-sitosterol, brassicasterol, and stigmasterol-were analyzed in soybean, sunflower, low-erucic acid rapeseed (LEAR) and com oils. The us...
