Anti-bacterial properties and GC-MS analysis of extracts and essential oils of selected plant product (original) (raw)

Nyaitondi OD, Wanjau R, Nyambaka H, Hassanali A. 2018. Anti-bacterial properties and GC-MS analysis of extracts and essential oils of selected plant product. Biofarmasi J Nat Prod Biochem 16: 44-58. Plants are traditionally used for the treatment of bacterial infections though they are not clinically regulated due to lack of awareness and sufficient data to support the reported therapeutic claims. Some plants used as food and vegetables are hardly considered in such studies. This study aimed to investigate the antibacterial properties associated with garlic, ginger, turmeric, lemon, and onion in the form of juices, methanol extracts, and essential oils. These materials were tested against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Salmonella typhi. Identification of suspected antibacterial compounds was made by comparison of retention indices and the mass spectra with those in National Institute of Standards and Technology (NIST) libraries using GC-MS analy...
