Results are expressed as mean ± standard deviation, n = 3. Mean values within a column superscripted by different letters are significantly different at . CR = crude, Hex = hexane, EA = ethyl acetate, AQ = aqueous. ORAC: oxygen radical absorbance capacity; FRAP: ferric reducing antioxidant power; ABTS: ABTS radical scavenging activity; DPPH: DPPH radical scavenging activity.
