Fig. 5From: Acid-base fractions separated from Streblus asper leaf ethanolic extract exhibited antibacterial, antioxidant, anti-acetylcholinesterase, and neuroprotective activitiesAnti-AChE activities of neutral and acidic fractions obtained from S. asper leaves. TLC chromatograms of neutral and acidic fractions (at 6.7 μg application) in a solvent system of hexane:ethyl acetate (7:3, v/v) were observed a under visible light, b by staining with KMnO4, and c by bioautographic method for screening on AChE inhibitory activity, where white spots against the dark background represent the inhibition. Galantamine (GA) was used as a positive control at 0.3 μg. Brackets indicate AChE inhibiting constituentsBack to article page
