The total phenolic and flavonoidal composition of the ethanolic extract of salvia libanotica was determinedusing the (FC) and aluminium chloride spectrophotometric methods. Quantitative HPLC was used for the identificationand quantification of each phenolic compound present in the extract. Chlorgenic acid, Naringenin, quercetin andhesperetin were found to be the major phenolic compounds in the extract. The antioxidant activity of the extract was tested using the DPPH scavenging assay. The extract has shown astrong scavenging activity with an IC50 = 8.73 μg/ml compared to the synthetic antioxidant BHT (IC50 = 91.40 μg/ml).
