Abstract

Two arsenic (As) hyperaccumulators (Pteris multifida and Pteris vittata) and a non-hyperaccumulator (Pteris semipinnata) were exposed to different As concentrations under hydroponic conditions. Five flavonoids in these fern species were determined by high-performance liquid chromatography (HPLC). Flavonoid production in P. multifida and P. semipinnata was also studied in 0 and 20 mg As L-1 treatments at different cultivation times. No significant differences were observed regarding the contents of quercetin, isoquercitrin and kaempferol in the fronds. The contents of rutin, quercetin, kaempferol and total flavonoids were also not significantly different in the roots of the three fern species under the same As treatment. However, significant differences were observed in contents of rutin, quercetin, hyperin, kaempferol and total flavonoids over time in the 20 mg As L-1 treatment. In general, the changes in flavonoid contents in the As hyperaccumulators were not directly related to As accumulation.
