| Popis: | We determined the physiological effects of glucotropaeolin-rich lyophilized garden cress sprout powder (GC) administered to fasting and nonfasting mice. High-performance liquid chromatography analysis revealed glucotropaeolin (57.4±1.1 mg/g dry weight) as a major phytochemical constituent of GC. Decreasing tendency in body weight and feeding efficiency ratio were detected in the group of mice fed 0.05% (w/w) GC (GC0.05). Nonfasting mice exhibited significantly lower liver weights that were unchanged after fasting. Decreased total lipid (TL) and triglyceride (TG) levels in the liver were detected in the nonfasted GC0.01 and GC0.05 groups, but only in TLs of the fasted groups. The levels of plasma TGs and nonesterified fatty acids of the GC0.05 group, which remained unchanged during nonfasting, decreased after fasting. To determine its effects on the accumulation of lipids in the liver, the glucotropaeolin aglycone, benzyl isothiocyanate (BITC), was added to the liver-derived HepG2 human cell line cultured in a medium containing a high concentration of D-glucose (4,500 mg/L D-glucose) (HG group) or 1 mM oleic acid (SO group). Toxicity was not detected when cells were treated with as much as 5 μM BITC; however, lipid accumulation was inhibited by BITC in a concentration-dependent manner in the HG groups. The same effect was observed when 2 μM BITC was added to the diet of the SO groups. These results suggest that moderate levels of GC or BITC are useful for reducing liver and plasma TGs. |
