Abstract: The aim of the current study is to compare the amount of some bioactive compounds (dietary fiber (DF) fractions, polyphenols, β-carotene, flavonoids and antioxidant activity) in dehydrated apple and pumpkin fruits It also aims to evaluate the influence of utilization of an appreciated amount, exactly contained 5% and 10% TDF) of dehydrated apples and pumpkins on body weight, organs weight, cholesterol fractions (total cholesterol, HDL, LDL and vLDL), triglycerides and liver enzymes (ALT and AST) of albino male rats fed on hypercholesterolemia diets for 6 weeks. The obtained data showed that the dehydrated apples and pumpkins were significantly different in their constituent of chemical analysis meanwhile pectin content had no significant difference and recorded 8.31 and 7.80 %, respectively. The dehydrated apples had a significant higher ratio of total dietary fibers and insoluble dietary fiber (30.3 ±2.45 and 19.8±1.56%, respectively) than the dehydrated pumpkins (22.7±1.93 and 13.14±1.34%, respectively); Meanwhile, no significant difference occurred in soluble dietary fibers. The amounts of phenoleic compounds, flavonoids, β-carotene, ascorbic acid and antioxidant activity showed significant differences in dehydrated apple and pumpkin. The biological analysis indicated that the apple and pumpkin showed a significant lower effect on body weight. The biochemical analysis of hypercholesterolemic rats fed on the tested dehydrated apples and pumpkins diets (each contained 5% and 10% TDF) were significantly lower in total cholesterol, LDL, vLDL, total lipids, and triglycerides, ALT and AST. Meanwhile, HDL was significantly increased.
It could be concluded that apples and pumpkins (which had higher contents of DF, polyphenols, β-carotene, flavonoiudes and antioxidant activity) showed hypocholesterolemic and hypolipidimic effects. These results suggest that dried apples and pumpkins could be considered as potential cholesterol – lowering ingredient in human diets or involved in preparing new formulations of fiber rich functional foods.
