Fatty acid composition, antibacterial and antioxidant potential of Atropa belladonna and Thymus linearis seeds grown in Kashmir

Abstract

Abstract In this study fatty acid composition of petroleum ether (AP and TP) and biological potential (Antioxidant and antibacterial) of chloroform (AC and TC), methanol (AM and TM) extracts of Atropa belladonna L. and Thymus linearis Benth. respectively was obtained by Soxhlet extraction technique from seeds were investigated. Fatty acid profile was obtained by gas chromatography mass spectrometry, antioxidant potential (DPPH-2,2-di-phenyl-1-picrylhydrazyl; ABTS-2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and antibacterial activity against (Pseudomonas aeruginosa, Serratia marcescens, Escherichia coli and Klebesiella pneumonia) was also performed. Linoleic acid was dominantly found with 74.42% in AP and 84.39% in TP. In antioxidant assays, the dominant inhibition was shown by AM (84.98% and 83.90%) and TM (85.27% and 83.29%) as compared to BHT (93.72% and 90.87%) for DPPH and ABTS radical scavenging respectively at 200 µg/mL. Moreover, AM and TM extracts showed good antibacterial activity. In conclusion, these plants could be selected as an adequate species in agricultural system, in food and pharmaceutical industries.
