WebMetal chelating activity The chelation of ferrous ions by extracts was estimated by method of Dinis et al. (Dinis et al., 1994). Briefly, 50 µl of 2 mM FeCl 2 was added to 1 ml of different concentrations of the extract (0.2, 0.4, 0.8, 1.6 and 3.2 mg/ml). The reaction was initiated by the addition of 0.2 ml of 5 mM ferrozine solution. WebDec 12, 2024 · 12th Dec, 2024. Khaleel A Abu-Sbeih. Al-Hussein Bin Talal University. The best way to get rid of iron is to raise the pH and make the solution slightly basic. This precipitates iron out as Fe (OH ...
WebThe chelation assay showed that compound 7 was chelated to metal via 6-CO and 5-OH on the benzopyrone ring. Theobserved protective effects of compound 7 towards crystallins from insults of UVC and free radicals may be due to its iron-chelating activity and its peak absorption at 254 nm.WebFerrozine assay is 1 – 14 ppm.
