Geometric Isomer Composition of Lycopene from Rat Liver
摘要
Abstract
Total lycopene amount and lycopene geometric isomer composition of rat liver were determined in this study, aiming to lay a foundation for in vivo studies on lycopene metabolism and biological function. In the experiment, male rats were administrated with tomato extract at a single dose. After 8 h, liver tissues were collected for the extraction of lycopene. The total amount and geometric isomer composition of lycopene were determined by C30-high performance liquid chromatography with photodiode array detection (C30-HPLC-PDA). Results indicated that total amount of lycopene from liver tissues was 92.95 μg/g fresh weight. In comparison with tomato extract, the composition and amount of lycopene Z-isomers (including 13Z-, 11Z-, 9Z-and 5Z-isomer) were increased in rat liver tissues. This phenomenon is important for investigating the storage, targeting transfer and biological function of lycopene in liver.关键词
