Figure 1: Separation of ME by TLC and antioxidant properties of its constituents. (a) ME was separated by TLC and visualized under UV at 254 nm. Major compounds appeared in a single band at (band A). (b) Screening of antioxidant activity was done by applying DPPH onto the TLC plate. Scavenging of DPPH was shown in yellow staining indicating antioxidative activity of ME.
