DPPH Radical Assay of F1-F3 F1 showed that most essential oils showed DPPH radical scavenging activity; the IC50 was 259 mg/mL. F2 were monitored with TLC and showed spots of chlorophyll, terpenes, and flavonoids that have DPPH activity, and their IC50 was 229 mg/mL. F3 fractions extracted with ethanol were components of the phenolic group and had the most inhibiting activities for DPPH radical scavenging	cache/easat-929.pdf	txt/easat-929.txt
