From: Investigation of antioxidant and antimicrobial activities of Euclea schimperi leaf extracts
UV–Vis absorbance of pure silver nitrate solution: a methanol extract b and chloroform extract c of Euclea schimperi leaves. The absorbance of the mixture was scanned between 300 and 600 nm using UV–Vis spectrometer after 2.0, 6.0, 9.0 and 24.0 h of the reaction begins. When it is stock, the absorption peak of methanol extract gave two non-smooth or trucks. From the UV–Vis absorbance of methanol and chloroform extracts, it was observed that the reduction of silver ions with chloroform extract was extremely smaller than methanol extracts
