Figure 1 demonstrate that the addition of increased volumes of hexane leaf extract and EDTA as a standard induces a significant (p [less than or equal to] 0,01) decrease dose-dependent in the optical density at 562 nm compared to the control suggesting that the hexane extract possesses a high capacity to iron chelate where the absorbance obtained decreased to a lesser extent 0,2 [+ or -] 0,011 compared to the EDTA (standard chelator) 0,04 [+ or -] 0,013.
