Abstract
In this research, methanolic extraction of Salvia leriifolia leaves produced a higher yield and antioxidative activity than other organic solvents (ethanol, acetone, chloroform, n-hexane). ‏The methanolic extract was reserved about 24 hours in the refrigerator and its precipitates were then separated. The extract was separated into 12 fractions by thin-layer chromatography (TLC). The highest yields were found in fractions with Rf values of 0.29, 0.54, 0.11 and 0.38 at 16.24%, 12.48%, 8.81% and 7.60%, respectively. All fractions and also whole methanolic extract and precipitates of methanolic extract had more anti-oxidative activity than the control based on the thiocyanate method. Whole methanolic ex-tract, precipitates of methanolic extract and most separated fractions showed more anti-oxidative activity than –tocopherol. The fraction with Rf value of 0.29 at 16.24% yield and 85.61% antioxidative activity of synthetic antioxidant BHT based on thiocyanat method was chosen as the fraction with the highest yield and the highest antioxidative ac-tivity.
