Comparative Analysis Of Total Polyphenol Content, Total Flavonoid Content And Antioxidant Potential Of Four Colored Flesh Potato Genotypes And Some Berries Fruits
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 10
Abstract
Antioxidants contained in vegetables and fruits are important for preventing the oxidative damages produced by free oxidant radicals, having a positive impact on the human health. Potato tubers with colored flesh contain antioxidants as do some of the berries fruits. This study evaluated the total polyphenol content (TPC), total flavonoids content (TFC) and antioxidant capacity (% of DPPH inhibition) of four potatoes genotypes with colored flesh tubers in comparison with cranberries, blueberries, blackberries and raspberries. The range for total polyphenol content (TPC) and total flavonoids content (TFC) in the food material tested was: (5464.3±87.643 - 10049.67±326.44 g GAE/g) and (46.067±9.259 - 510.4±2.113g QE/g) respectively. The potential antioxidant activity of the purple potato tubers backed was closed to that obtained for raspberries. DPPH scavenging activity in all samples (berries and backed purple potato tubers) was positively correlated with TPC and TFC. The advantages of the colored flesh potato tubers consumption are: the special bioavailability of this plant, economic considerations (lower price compared to other rich sources of polyphenols like the berries) and the presence of valuable antioxidants (increasing the nutritional value of this food).
