Journal of Food & Nutritional Disorders
The antioxidant activity of organic solvent extracts from green mate leaves (Ilex paraguariensis), lotus plumule (Nelumbo nucifera Gaertn.) and fresh rhubarb (Rheum rhabarbarum L.) stalks was investigated using four antioxidant assays. An extract obtained with 60% methanol solution from mate leaves exhibited antioxidant activity of 99.96 ± 1.20% at the level of 2000 g/mL (TBA assay) and of 81.80 ± 0.54% at the level of 125 g/mL (DPPH assay), respectively.
