Phytochemical and Antimicrobial Properties of Oil Extracts from the Seeds of Ricinodendron heudelotii

Conclusion: Amongst the bacteria used, highest MIC of 150 mg mL–1 was recorded for Staphylococcus aureus, while lowest MIC of 50 mg mL–1 was observed in E. coli. Highest activity was observed against the fungus, Candida albicans with MIC of 25 mg mL–1.

FAME is an ideal super-curator and superior anti-pathogenic. The present study evaluated the efficiency of FAME extracted from microalgae Scenedesmus intermedius as an antimicrobial agent against Gram positive (Staphylococcus aureus, Streptococcus mutans, and Bacillus cereus) Gram negative (Escherichia coli and Pse...

Compound library was synthesized by reaction with alkyl, alkenyl, alkynyl and alicyclic bromo-compounds. Characterization of the synthesized compounds was performed by 1H NMR, 13C NMR and mass spectral techniques. The compounds w...

Abstract ObjectivePathogenic contamination of cosmetics intended to be applied on or around the eye area, including make‐up removers, may lead to severe eye infections. To assess the efficacy of antimicrobial preservatives in these products, we investigated the survival and detection of Bacillus cereus F 4227A spiked into make‐up removers, alone and in the presence of other relevant micro‐organisms. MethodsFour brands of make‐up removers, A, B, C and D, were challenged three times (day 0, day 7 and day 14) using B. cereus, in pure and mixed cultures, at a final concentration of 5 log CFU per mL of Bacillus cereus o...

Abstract Natural extracts (anthocyanins, tannin, anatto, curcuma and olive leaf extracts) were encapsulated within a silica network by acid or base-catalyzed sol-gel methods. The nominal encapsulated contents were between 2.5 and 50wt.-%. The resulting materials were characterized by Fourier transform infrared spectroscopy, diffuse reflectance in the UV region, nitrogen adsorption/desorption porosimetry and small angle X-ray scattering. Encapsulated anthocyanin and tannin afforded inhibition zones between 9-21mm towards Staphylococcus aureus, Escherichia coli, Bacillus cereus, Candida sp. and Aspergillus niger, wh...

Abstract New series of cyclopenta(hepta)[b]thiophene and fused cyclohepta[b]thiophene analogs were synthesized. The new analogs were assessed for antibacterial efficacy toward Escherichia coli ATCC 12435, Bacillus cereus UW 85 and Staphylococcus aureus. Compounds 5a, 6b and 12 showed eminent activity toward all selected bacterial strains compared to ampicillin. The antifungal efficacy of the same analogs was also examined toward Candida albicans and Aspergillus fumigatus 293, whereas 5a,b and 12 showed excellent efficacy toward both of the tested fungi. Moreover, 4b, 6a, 14a and 17 demonstrated interesting antifun...
