In this study, six laser radiation (488 nm/40 mW, 514 nm/15 532 nm/20 552 660 nm/ 75 and at 785 nm/70 mW) were tested on the aqueous extracts of leaves Plantago lanceolata L. to compare extraction efficacy antioxidant cell viability effects in vitro. Briefly, comparison with control extract, 488, 514, 532, nm revealed small acquisitions total extractible compounds samples (up 6.52%; 488 also mi...
