The aim of this study was to investigate the presence of toxins and their mutagenicity in 9 commonly consumed plants in Kanjanaburi Province, Thailand. Natural toxins including saponin, glycoalkaloids, lectin and heavy metals (Pb, Cd, total As) in soil, water and plants were determined. The chemical analysis was done using HPLC, ICP-MS and mutation degree was based on Drosophila assay. The results indicated that the concentration of phytotoxins in selected plants was low (3-60 mg/g DW). In addition, no heavy metals were detected in the water while low concentrations were detected in the soil and plants ranging 0.02-0.32 mg/kg for Pb, 0.04-0.17 mg/kg for Cd and 0.013-0.147 mg/kg for total As. Regarding mutagenicity, all samples tested by the assay showed no mutation except Careya sphaerica Roxb. for which an initial concentration led to smaller size Drosophila flies. The results indicate that areas with minimum human activity could also be contaminated with naturally occurring heavy metals such as Pb and As. However, all toxins and mutagenicity were within the limits as defined by the Thai food safety regulations. Moreover, at moderate consumption, these studied plants did not exhibit toxic effects.
