Over the last decades, endophytic fungi represent a new source of pharmacologically active secondary metabolites based on underlying assumption that they live symbiotically within their plant host. In present study, fungus was isolated from Rauwolfia macrophylla, medicinal Cameroon. The showed highest homology to Curvularia sp. complete nucleotide sequence data generated internal transcribed spacer (ITS) ribosomal DNA region. Large scale fermentation, working-up and separation strain extract...
Currently, the exploration of natural colorants from vegetal waste has gained particular attention. Furthermore, incorporation these sources into biopolymers is an encouraging environmentally friendly approach to establishing active films with biological activities for food packaging. The present study developed bioactive antioxidant based on gelatin-sodium alginate (NaAlg) incorporated aqueous beetroot peel extract (BPE). Firstly, effects combining gelatin-NaAlg and BPE at 0.25, 0.5, 1%...
Given the significant quantity of betalain pigments, beetroot represents a potential source natural colorants that can be employed in food industry. The present investigation explored impact ethanolic peel (EBP) extract beef meat preservation. EBP displayed 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effect with an IC50 value 0.96 mg/mL. anti-S. aureus, anti-L. monocytogenes, anti-E. coli, and anti-Salmonella enterica activity was assessed, minimum inhibitory concentration ≤1.5...
During our search for Streptomyces spp. as new producers of bioactive secondary metabolites, the ethyl acetate extract terrestrial isolate TN262 delivered eight antimicrobially active compounds. They were identified 1-acetyl-β-carboline (1), tryptophol (2), cineromycin B (3), 2,3-dihydrocineromycin (4), cyclo-(tyrosylprolyl) (5), 3-(hydroxyacetyl)-indole (6), brevianamide F (7), and cis-cyclo-(l-prolyl-l-leucyl) (8). Three further metabolites detected in unpolar fractions using GC–MS...
Summary Microbiological, chemical and sensory effects of pomegranate peel ethanol extract (EE) at 0.1, 0.5 1% (w w −1 ) on refrigerated minced beef meat were undertaken. Chemical analyses revealed that the treated underwent significant decrease (P < 0.05) primary secondary lipid oxidation. By end storage, EE reduced MetMb, carbonyl group accumulation disappearance sulphydryl proteins by 56.68, 65.71 59.69% respectively, compared with control samples. showed also highest scores for colour,...
