“…Acetone extract also exhibited the highest antioxidant activity by the ferric reducing antioxidant power (FRAP) assay and the oxygen radical absorbance capacity (ORAC) assay. The values obtained in this study were similar to those obtained in the of Fuji apple peel acetone extract and beetroot and broccoli acetone extracts (Ou et al, 2002;Henriquez et al, 2010).…”

“…The phenolic compounds were chief phytochemicals responsible for antioxidant properties in Helicteres isora L., as indicated by strong positive correlation between TPC and FRAP, DPPH assays. Similar correlation was found between TPC and antioxidant capacity in the extracts of caper [25], apple [33] and guava [34].…”

Abstract:Helicteres isora L., commonly known as Indian Screw Tree is a highly valued medicinal plant in South-East Asia.The various phytochemicals like phenols, flavonoids and other antioxidants that impart the medicinal properties in this plant, vary in their composition and concentration in different plant parts. In the present research, the total phenolic content, total flavonoids content and free radical scavenging activity (FRAP and DPPH assay) in fresh and dry sample extracts of leaf, bark, fruit and root of H. isora L., prepared in four different solvents (distilled water, ethanol, methanol and acetone) were studied, and their results compared using Pearson's Correlation. The plant extracts were also subjected to RP-HPLC for detection and quantitation of naturally occurring phenolic compounds using six phenolic standards (Gallic acid, Vanillin, Catechol, Ferrulic acid, p-coumaric acid and Caffeic acid). The highest total phenolic content (7.22 mg/g GAE) and FRAP value (64.98 mg/g TE) were observed in aqueous dry root extract. The acetone extract of fresh leaf (57.08 mg/g of RE) was found richest in total flavonoids, while the methanolic extract of fresh fruit uniquely exhibited strong free radical scavenging activity as evidenced by the low IC50 value (34.37 mg/ml) in DPPH assay. The RP-HPLC analysis revealed that Catechol and Gallic acid were most abundantly found phenolic compounds in extracts of H. isora L. The total phenolic content showed strong positive correlation with free radical scavenging activity (FRAP and DPPH assays) in both fresh and dry plant parts, suggesting that phenols are the main compounds responsible for the antioxidant activity. The root of H. isora L. was found rich in phenolics and antioxidant capacity indicating its strong potential for medicinal use, followed by fruit, leaf and bark.

“…Apples are considered a good source of dietary minerals [14]. In accordance with previous reports [2,14,20,21,22,23], K, Ca and Mg were the main minerals present at high concentrations in the present apple cv. In contrast to the above studies, our phosphorus (P) values were very low in the present apple fruit.…”

The purpose of this study was to evaluate physicochemical parameters and nutritional changes in the whole fruit, the peel and the flesh parts in fruit of 'Göbek' apple during three ripening stages over a 20-day period (188 to 208 DAFBs) on the tree. A significant (P < 0.01 or 0.05) increasing trend for pH, total soluble solids, dry matter, sweetnes index, total sweetnes index and a decreasing trend for total soluble solids:titratable acidity, titratable acidity, fruit firmness and moisture content were observed through ripening. The nutrient analysis representing the major components in the peel and flesh (respectively) indicates fructose in the range of (ave. 2260.1 and 3486.1mg/100 g fw), malic acid (ave. 1052.8 -278.6 mg/100 g fw), palmitic acid (ave. 33.1 -26.8%) and linoleic acid (ave. 21.1 -18.23%), potassium (ave. 186.3 and 105.6 mg/100 g fw) and asparagin (ave. 149.3 -59.8 mg/100 g fw). Among the polyamines analyzed, spermidin was the most abundant polyamine in the peel and flesh in the following range (ave. 281.6 and 124.7 nmol g -1 fw). The ripening process affected nutrient concentrations in the fruit as the maturity progressed on the tree. 'Göbek' fruit could be an excellent potential source for specific nutrients if it is harvested at different ripening stages.
