Proximate chemical composition and biological profile of fatty acids of Withania somnifera L dunal

The fixed oils extracted from the fruit (berry) of Withania somnifera were evaluated for their chemical composition. The gas chromatography-mass spectrometry (GC-MS) analysis shows the presence of various saturated and unsaturated fatty acids present in the roots of Withania somnifera. The total eight fatty acid compounds were identified by GC-MS with the library searches scale with varying percentage such as linoleic acid (11.247%), linoleic acid (4.000%), palmitic acid, (2.842%) and tetracosanoic acid (0.880%), palmitic acid (0.42%), lenoleic acid (0.23%), oleic acid (0.14%), elaidic acid (0.01%). The fixed oil was evaluated for different biological activities such as phytotoxicity, antibacterial, antifungal, cytotoxicity, antibacterial, and antiurease activities. The oil shows moderate percent inhibition against the entire activities. The oil shows dose dependent DPPH radical scavenging activity.
