Abstract
The present investigation determines the phytochemical analysis, antioxidant and antibacterial potential of methanol extract of Himalayan Fraxinus micrantha (Lingelsh) leaves. Chemical analysis of extract revealed the presence of fifty five compounds. The extract was strongly characterised by tyrosol, esculetin, β-sitosterin, l-(+)-ascorbic acid 2,6-dihexadecanoate, (Z,Z)-6,9-cis-3,4-epoxy nonadecadiene as main components (62.6%). The F. micrantha extract presents IC50, 43.93 µg/ml and 68.90 µg/ml using DPPH and H2O2 scavenging assay, respectively. The antibacterial activity of F. micrantha was evaluated for five microorganisms showed that the extract had a remarkable inhibitory potential with a mean zone diameter of inhibition ranging from 11 to 22 mm. The MIC of the extracts ranged from 7.8 to 250 µg/ml and MBC value range 31.25 to 125 µg/ml. F. micrantha showed significant antibacterial activity against B. subtilis (22 mm, ZOI) with MIC and MBC values 7.8 and 31.25 µg/ml respectively.
