Davis was collected from Kemer, Antalya. The aerial part of plant materials were dried and powdered then boiled in water. After filtration, water phase was partitioned with ethyl acetate and n-butanol sequentially. After removal of the solvent by rotary evaporator, the chromatographic methods were applied for ethyl acetate extract to isolate the bioactive compounds. 3,4-dihdroxy benzoic acid (protocatechuic acid) (1), 3,4-dihydroxy benzaldehyde (protocatechuic aldehyde) (2), 2- <i>O-ß </i>-D- glycopyronozyl-4,6-dihydroxyacetophenone (myrciaphenone) (3), caffeic acid (4), rosmarinic acid (5), lithospermic acid B (6) were isolated by chromatographic techniques (column chromatography, preparative HPLC) and spectroscopic methods (1D, 2D NMR, LC-TOF/MS) were used for elucidation of isolated compounds. All isolated natural products revealed the outstanding activities on antioxidant assays including DPPH <sup>• </sup>free radical scavenging, ABTS <sup>•+ </sup> radical cation scavenging, and reducing power (FRAP). <o:p> </o:p> </span> </p>}, number={1}, publisher={ISRES Publishing}
