Total Phenolic Content, Flavonoid Content and Antioxidant Potential

There was a strong correlation between antioxidant activity with total phenolic (DPPH, R 2 = 0.75; H 2 O 2, R 2 = 0.71) and total flavonoid content (DPPH, R 2 = 0.84; H 2 O 2, R 2 = 0.66). This study demonstrates that these wild edible leafy plants could be a potential source of natural antioxidants.

2.2.1 Principles and Characteristics. Colorimetric assays to determine total phenolic contents are often based on the ability of phenolic compounds to be oxidized. Permanganate and ferric ions were applied as oxidation reagents in the past, with ferric ions still used to measure the antioxidant capacity of plant foods.

This study aimed to determine the standard amount of antioxidant content and compounds of the propolis for the standardization of propolis. For this purpose, the total flavonoids, total phenolic, CUPRAC antioxidant capacity content and the diversity of phenolic and flavonoid components of these propolis samples were found by HPLC determined at the 23 propolis samples which were collected
