The data express means ± standard deviation (SD). Different letters in a column indicate significant differences at p < 0.05. MM, total methanolic extract; MH, hexane extract; ME, ethyl acetate extract; MW, water extract; BHT, butylated hydroxytoluence; PA, palmitic acid; “-“, not measured; ne, negligible effect; na, no activity.
