Prospective antimycotoxigenic action of wild Opuntia ficus-indica by-products

Abstract

Numerous natural compounds perform pharmaceutical, antimycotic and antitoxic purposes in the body system. The aim was to evaluate new phytoconstituents that provide antimycotoxigenic properties against mycotoxins. Bioactive materials chosen were fruit peels and cladodes of wild Opuntia ficus-indica containing a measurable quantity of bioactive phytochemicals. The highest concentration of bioactive metabolites was recorded for protocatechuic and t-cinnamic acids. A reduction effect of bioactives was estimated against aflatoxins, ochratoxin A and zearalenone in a simulated body system. Antifungal activity was determined in liquid media to evaluate antimycotic properties. Lyophilised extracts caused an aflatoxin reduction in media by 14.65% to 23.77% for fruit peels and cladodes, respectively. It caused a decrease of 59% zearalenone and 51% of ochratoxin A in a in a simulated body fluid. The cladode extract manifested better antimycotic and antimycotoxigenic characteristics due to its bioactive contents. These results support a modern antimycotoxin trend of food preservation that has a considerable impact on food safety.

Efficacy of Bottle Gourd Seeds’ Extracts in Chemical Hazard Reduction Secreted as Toxigenic Fungi Metabolites

“…Besides, extracts of plants showed a valuable capacity for toxigenic fungal growth (assessed in synthetic media) [14,15]. The promising impacts of wild plants like stevia, Opuntia Ficus indica [16,17], and star anise [18] were recorded. Also, extracted seed oils showed a significant ability to inhibit mycotoxin production by their toxigenic fungi strains, among which were jojoba, jatropha [19], black cumin seed [20], pomegranate oil [21], and hibiscus oils [22].…”

Bioactivity evaluation for volatiles and water extract of commercialized star anise

“…These impacts are forcing fungi to produce mycotoxin as a cell-defense system [ 35 ]. The previous investigations revealed the efficacy of plant phenolic extracts against fungal growth and mycotoxin production [ 13 , 45 ]. The mechanism of volatiles and phenolics to reduce mycotoxin, depending on these components' function as antioxidants, helps the fungi cell mitigate oxidative stress during their growth [ 37 ].…”

“…Concerning the investigation results, implicated extracts showed a potent inhibition effect for the growth of toxigenic fungi, with more efficacies for volatile extract (of solid and liquid media; Figure 2 ). This inhibition is associated with the presence of bioactive components [ 37 , 45 ]. Several compounds, which are existed in volatile extracts sourced from agro-food materials, were reported to possess antimicrobial impacts against pathogens [ 47 ].…”

“…This potency was reported for both in vivo [ 23 , 38 , 39 ] and in vitro [ 26 , 48 , 49 ] implementations. Also, it considers pretty when plant extracts possess activities to inhibit toxin-producing fungi or the ability to reduce their mycotoxins [ 24 , 29 , 38 ]. The impact of these extracts is mainly joined to their antioxidant potency [ 47 ].…”

“…Bioactive components represented an efficacy for fungal inhibition and mycotoxin reduction. These bioactives, which are applied in food manufacturing, could be sourced microbiologically as metabolites [ 21 , 22 ], or as plant extract [ 7 , 23 , 24 ]. The bioactive carbohydrates including dietary fibers have a positive impact as antimycotic and anti-mycotoxigenic agents against the toxigenic fungi activities on food commodities [ [25] , [26] , [27] ].…”
