Comparative content of some bioactive compounds in apples, peaches and pears and their influence on lipids and antioxidant capacity in rats

Antioxidant potential of extracts from different agro wastes: Stabilization of corn oil

“…Within peels, the highest TP were found in pomegranate (36.40%), followed by apple (3.90%), citrus (2.4%), and banana (1.1%). The results of TP for pomegranate peels in the present work were found to be higher than those reported by Li et al, (2005), however, lower than that of Negi et al, (2003), while that of apple were higher than the earlier report (Leontowicz et al, 2002), although comparable with the results of Wolfe and Liu, (2003). Citrus and banana peels also contained appreciable amounts of TP, which were relatively higher than earlier reports (Anagnostopoulou et al, 2006;Someya et al, 2002).…”

Effect of gala apples (Malus domestica Borkh) on lipidemia of hyperlipidemic rats

“…Several investigations have shown that fruits are a natural source of dietary fiber, trace elements and antioxidant compounds, and that diets rich in fruits positively influenced plasma lipid levels and antioxidant capacities in experiments with laboratory animals GORINSTEIN et al, 2002;LEONTOWICZ et al, 2001;LEONTOWICZ et al, 2002). Boyer and Liu (2004) found that the total antioxidant activity of apples with their peel was approximately 83 µmol vitamin C equivalents, which means that the antioxidant activity of 100 g apples is equivalent to about 1500 mg of vitamin C.…”

“…More studies investigated these parameters using apples, pears and peaches, with apples having the greatest effect (BOBEK; OZDÍN; HROMADOVÁ, 1998;LEONTOWICZ et al, 2003). Apples contained more phenolic compounds, suggesting that perhaps the phenolics in apples contribute to this effect ( LEONTOWICZ et al, 2002). Figure 3 shows the effect of the experimental diets on the serum levels of LDL-C at 30 and 60 days of the treatments.…”

The regular consumption of a polyphenol-rich apple does not influence endothelial function: a randomised double-blind trial in hypercholesterolemic adults

“…Moreover, apple consumption has been associated with a reduced risk of cardiovascular diseases in the Women's Health Study, as women ingesting apples had a 13-22% decrease in cardiovascular disease risk (Sesso et al, 2003). Animal studies revealed that the consumption of apples exerts antioxidant effects (Leontowicz et al, 2002), inhibits lipid oxidation (Pearson et al, 1999) and lowers cholesterolemia (Aprikian et al, 2001;Leontowicz et al, 2002). Mechanisms involved in these protective effects can be attributed to their fiber content as well as their polyphenol content, which are known to have preventive effects against cardiovascular diseases.…”
