Figure 1: DPPH free radical scavenging activity of Murraya koenigii leaf fractions (petroleum ether, benzene, ethyl acetate, acetone, methanol, and ethanol) at different concentrations (12.5–100 μg/mL). The activity is compared with commercial antioxidants, ascorbic acid and BHT. Each data point represents the mean of three experiments. Standard deviation (≤4%) is not shown for clarity of the data.
