Sample text

Poor et al. (224) used HPLC analysis to study the accumulation of α- and β-carotenes in serum and tissues of preruminant calves fed raw and steamed carrot slurries. Serum and various tissues of ferrets following a dose with β-carotene were extracted with a mixture of chloroform-methanol (2: 1) followed by extraction with hexane; the extracts were analyzed by HPLC (225–229). Rat Hepatoma Cells. Cis-trans conversion of β-carotene in FU-5 rat hepatoma cells was studied by HPLC analysis of cell extracts using a 5-µm Suplex PKB 100 column and a mobile phase of methanol/dichloromethane (97: 3) (230).

Column chromatography on DEAE-Toyopearl with acetone followed by another column chromatography on silica gel with hexane, followed by HPLC on a C18 cartridge with methanol, was used to isolate and purify a novel carotenoid ester, loroxanthin dodecenoate, from Pyramimonas parkeae and from a chlorarachniophycean alga (262). Braunixanthins 1 and 2 were separated and characterized as new carotenoids in the green microalga Botryococcus braunii by column chromatography on silica gel and ODS, followed by HPLC on a Develosil 60-3 column 49 Copyright  2000 by Marcel Dekker, Inc.

A C18 column with an isocratic mobile phase of acetonitrile : water :methanol : n-butyl alcohol: ammonium acetate :acetic acid was used. Lower limits of detection were on the order of 80 to 170 nM (25 to 50 ng/mL) for retinoic acid and its metabolites, using absorbance detection; an anthracenyl retinoid was used as internal standard. A similar extraction procedure was used by Guiso et al. to analyze retinoic acid and its metabolites in human plasma; proteins were precipitated with acetonitrile, 37 Copyright  2000 by Marcel Dekker, Inc.
