Table 3: Antioxidant activity of the extracts from leaves of _P. Lancolata_ (\(\pm\)SD, \(n=3\)). Laser-assisted extract at 532 nm (yellow line in series c. Plal532) indicated a pro-oxidant activity in comparison with both control extracts (at 1 h and 2 h, respectively), but similar results in comparison with control negative sample (PlaC). These results suggest more augmented, but also reversible electronic transitions of laser irradiation at 532 nm upon the vegetal material, as resulted from the previous studies [6].
