The antimicrobial activity of roots ofJatropha podagrica (Hook)

Abstract

Hexane, chloroform and methanol extracts of the rootwood and rootbarks of Jatropha podagrica were studied for their antimicrobial activity against 18 organisms. All the extracts exhibited some broad spectrum antibacterial activity, at a concentration of 20 mg/mL. The hexane extracts were generally more active than the chloroform and methanol extracts. The hexane extract of the yellow rootbark was the most active of all the extracts and its activity was comparable to that of gentamycin but better with regard to the control of S. aureus and B. cereus. Three of the extracts, hexane extract of the yellow rootbark and hexane and methanol extracts of the rootwood showed moderate antifungal activity against the yeast fungus, Candida albicans.

Evaluation of three medicinal plant extracts against <i>Plasmodium falciparum</i> and selected microganisms

“…Various medicinal and pesticidal properties including antibacterial (pneumonia), antitumor and insect antifeedant have been attributed to this plant (Odebiyi, 1980). Phytochemicals in different parts of the plants includes flavonoids, steroids, alkaloids and diterpenoids have been isolated and characterized (Aiyelaagbe et al, 2007(Aiyelaagbe et al, , 1998; Das and Venkatail, 2006).…”

Evaluation of extracts of Jatropha curcas and Moringa oleifera in culture media for selective inhibition of saprophytic fungal contaminants

“…The minimum inhibitory concentration (MIC) at which the extracts of J. curcas and M. oleifera prevented the growth of laboratory contaminants, while allowing good growth of clinical pathogens, was determined. The enhancement of growth of some fungi and the inhibition of others, at different concentrations of extracts of these plants, have been reported by other workers (5,7,9,10). At a concentration of 0.75 and 1.0 mg ml À1 of the extracts of Jatropha and Moringa, respectively, the contaminants, A. niger, A. terreus, and P. expansum, were inhibited.…”

A scoping review of the use of traditional medicine for the management of ailments in West Africa

“…Other disorders managed were eye infection [ 31 , 56 ], infertility [ 31 ], leprosy [ 41 , 43 ], ulcers [ 43 ], meningitis/encephalitis [ 34 ], smallpox [ 43 ], urinary tract infection [ 44 , 56 ], sore throat [ 23 ], gonorrheal [ 23 ], schistosomiasis [ 45 ] and rhematic pain specifically [ 41 , 54 , 56 ]. Some studies explored specific antifungal [ 18 , 20 , 42 , 48 , 49 , 51 ], antibacterial [ 18 , 20 – 23 , 25 , 26 , 30 , 35 , 42 , 46 , 49 , 52 , 53 , 59 ] and antiviral [ 34 , 46 , 59 ] effects of plant extracts.…”

“…Sixty plant families were studied (See S3 File for the compendium). The most common plant family studied were Euphorbiaceae [ 18 , 21 , 29 , 38 , 40 , 41 , 42 , 44 , 45 , 47 , 50 , 55 ], Rubiaceae [ 19 , 20 , 26 , 30 , 35 , 40 , 44 , 46 , 55 , 57 , 59 ] and Combretaceae [ 14 , 23 , 30 , 35 , 44 , 51 , 55 ]. The 12 studies on Euphorbiacea were conducted in Nigeria [ 18 , 21 , 38 , 41 , 42 , 48 ], Ghana [ 29 , 40 , 45 , 50 ], and Cote D’Ivoire [ 44 , 55 ].…”
