Abstract :The study was aimed to determine the gallic acid, rutin and quercetin contents and yield of Narli onion genotype insert ignore into journalissuearticles values(Allium cepa L.,); exposed to four different doses insert ignore into journalissuearticles values(0, 25, 50, 75, 100 mg L-1); of silver nanoparticles insert ignore into journalissuearticles values(AgNPs);for30 days, after planting the onion bulbs, attwo-week intervals. Quercetin, rutinand gallic acid contents in the leaves and bulbs of onion plants were determined.While the quercetin content was the highest in 25 mg L-1ofAgNPs treatment insert ignore into journalissuearticles values(575.0 ± 10.39 µg g-1);in the bulb parts, gallic acid content reachedtothe highest rate in 50 mg L-1 of AgNPsinsert ignore into journalissuearticles values(3605.8 ± 90.96µg g-1);, inthe onion bulb, compared to the control insert ignore into journalissuearticles values(2819.3 ± 65.72µg g-1);.The content of rutinwere enhanced in 25 insert ignore into journalissuearticles values(19.72 ± 0.28µg g-1);, 50 insert ignore into journalissuearticles values(21.66 ± 0.57µg g-1); and 75 mg L-1insert ignore into journalissuearticles values(31.08 ± 0.53 µg g-1); of AgNPs treatments, but it was significantly close to the control insert ignore into journalissuearticles values(7.15 ± 0.93µg g-1);, in100 mg L-1insert ignore into journalissuearticles values(10.92 ± 0.38 µg g-1);, in bulb parts.Chlorophyll content showed reducesin all doses, except for25 mg L-1 of AgNPs treatment. Total yield enhanced in treatments of AgNPs, but the highest increase was obtained in treatment of 50 mg L-1 of AgNPs insert ignore into journalissuearticles values(97.49 ± 0.92 µg g-1);. The analysis of quercetin, rutin and gallic acid contents were performed by high performance liquid chromatography insert ignore into journalissuearticles values(HPLC);, and Chlorophyll was determined by SPAD.
