Abstract
Abstract Plant oils are diversely used in different industries around the globe for various purposes and for such reasons the oil extracted from whole plant of Sambucus wightiana was investigated for their bioactivities and fatty acid profiling through Gas Chromatography–Mass Spectrometry (GC-MS). The antibacterial activity of the oils was determined using disc diffusion method against various bacterial pathogens; Escherichia coli, Serratia marcescens, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi and were found inactive. The oils of the plant showed low or no antifungal activity against test fungi; Trichoderma harzianum, Paecilomyces fulvus, Aspergillus flavus, Alternaria alternata, Fusarium oxysporum, Rhyzopertha stolonifer and Polysphondylium pallidum. The phytotoxic activity of oil was determined against Lemna minor (L) and result revealed moderate and low activity at all test concentrations. No insecticidal effect was recorded for the extracted oils against test insects; Tribolium castaneum, Rhyzopertha dominica and Callosbruchus analis. The fatty acid profile of S. wightiana showed various components present in different concentration with highest percent of Palmitic acid (46.34%) followed by Stearic acid (23.64%), Linoleic acid (11.48%), Heptadecenoic acid (8.2%), Myristic acid (3.09%), Margaric acid (2.14%), Eicosatrienoic acid (1.88%) and Eicosanoic acid (0.98%).
