Br., Brassicaceae). It has ecological and economic importance and has been used by humans for many years both for food and medical purposes. Now it is reported to have a chemopreventive effect. In this study, Watercress samples were collected from Malatya, Turkey. Spectrophotometric methods were used to determine the antioxidant activity and the content of total phenolic and phenylethyl isothiocyanate. To determine heavy metals and trace elements watercress were used inductively coupled plasma-mass spectrometry (ICP-MS). Our results indicated that the extract of watercress has a high antioxidant capacity. This feature was related to phenolic compounds and phenylethyl isothiocyanate. Our analysis with ICP-MS has revealed that the watercress plant has high iron content and toxic heavy metals did not bioaccumulate in the watercress plant. So it is recommended to consume the watercress plant as food according to these results. However, toxicity studies should be carried out in living beings regarding plant intake.eninfo:eu-repo/semantics/openAccessICP-MSDPPHPEITCWatercressArticle34653754310.9755/ejfa.2022.v34.i6.28982-s2.0-85141167903Q3WOS:000869967100010Q4
