“…The Anthocyanins Quantification was realized using the differential pH method adopted by Barragán et al [ 19 ]. For this method, 5 g fresh samples were used in test tubes with 5 mL of two buffer systems: potassium chloride (KCL) pH 1.0 (0.025 M) and sodium acetate (CH 3 COONa) pH 4.5 (0.4 M).…”

Comparative Assessment of Antioxidant Activity and Functional Components of Chionanthus virginicus and Chionanthus pubescens from the Andean Region of Ecuador

The present study aims to provide information about the antioxidant capacity and secondary metabolites from different plant parts of two species that are grown in Ecuador: Chionanthus pubescens (the Ecuadorian national tree), and Chionanthus virginicus (the fringe tree—endemic to the United States of America and adapted to Ecuador’s physiographical and ecological conditions). These two species have still not been investigated for these characteristics. A comparative estimation of the antioxidant activities between the leaf, fruit, and inflorescence extracts was performed. In the quest for new medicines, the extracts were analyzed for phenolic, anthocyanin, and flavonoid content. A slight difference was observed between C. pubescens and C. virginicus flowers, the highest antioxidant activity being found in the C. pubescens leaf (DPPH IC50 = 62.8866 mg/mL, ABTS IC50 = 55.852 mg/mL, and FRAP IC50 = 2.8466 g/mL). Our results showed correlations between antioxidant activity, total phenolic content, and flavonoids. This study confirmed that the C. pubescens leaves and fruits from the Andean region of Ecuador represent a good source of antioxidants, especially due to the presence of a high content of phenolic compounds (homovanillic acid, 3,4 dimethoxyphenylacetic acid, vanillic acid, gallic acid, etc.) as determined by the HPLC-DAD method.

Functional beverages with added health benefits are popular among peoples and athletes because they help them recover faster from intense workouts and perform better overall. This research set out to determine how well heat-treated stem juice from Oxalis tuberosa Mol. “oca” and fruit juice from Gaultheria glomerata (Cav.) Sleumer “laqa-laqa” performed as an antioxidant in a functional drink. The “oca” stems and the “laqa-laqa” fruit were collected to obtain the juice. For this study, 30 semi-trained panellists used sensory evaluation to rate four treatments (Bo, B1, B2, and B3) with varying quantities of “oca” and “laqa-laqa” juice. The results concluded that the treatment B2, which included 300 ml of “oca” stem juice, 800 ml of “laqa-laqa” juice, 1000 ml of treated water, and 220 g of refined sugar, was given the highest score after a physicochemical evaluation of its colour, smell, taste, and overall appearance. Similarly, the results showed that the protein content increased by 1.38%, the fat content by 1.08%, the moisture percentage by 99.5%, the ash content by 1.82%, and the carbohydrate content by 6.22% after B2 treatment. Similarly, results revealed significant enhancement in antioxidant profiling such as total polyphenols: 1825 mg of gallic acid/100 g and antioxidant Activity: 89.56% μmol of trolox /100 g. In conclusion, due to its high energy content and antioxidant activity, it may be a viable nutritional option for athletes who engage in rigorous, frequent physical exertion.
