Antioxidant Activities of corn silk–lemon and commercial tea infusion. A DPPH radical scavenging activities using spectrophotometric method reported by Gyamfi et al. (1999). The absorbance of the mixture prepared from dilution of the infusion and solution containing DPPH radical was read at 516 nm. The percentage DPPH radical scavenging ability of the extracts was calculated as percentage of control. The percent DPPH radical scavenging ability was plotted against five samples extract concentration (ug/ml). B Hydroxyl radical scavenging activities as described by Halliwell et al. (1987) and tis was used to determine the ability of the extracts to prevent Fe₂₊/H₂O₂ induced decomposition of deoxyribose. Spectrophotometer was used to take the absorbance reading of the solution prepared from the mixture of the extracts (0–200 µl) and reaction mixture. The percent hydroxyl radical scavenging ability was plotted against five samples extract concentration (ug/ml). CSF: corn silk flour; LF: lemon flour; A: 100% CSF; B: 95% CSF and 5% LF; F: top tea; L: lipton tea; G: green tea
