From: Investigation of antioxidant and antimicrobial activities of Euclea schimperi leaf extracts
UV–Vis absorbance of different concentration of methanol extract of Euclea schimperi leaves after different reaction time. As the contact or reaction time increases, the formation of silver nanoparticles increases which leads to an increases in absorbance of the mixture. The peak observed in the methanol extract is clearly visible around 428 nm which indicates the reduction of silver ions
