Correction to: Characterization, antioxidant, and cytotoxic effects of some Egyptian wild plant extracts

Edible wild plants were investigated as potential sources of antioxidants and prebiotics to benefit human health. Antioxidant activity, ascorbic acid and total dietary fibre contents were determined in edible wild plants from Lesotho, Swaziland and South Africa. Pure probiotic strains of Bifidobacterium animalis subsp. animalis (ATCC 25527), Lactobacillus rhamnosus (TUTBFD) and Lactobacillus acidophilus (ATCC 314) were cultured in broth containing edible wild plant extracts to assess their prebiotic activity. Cyperus esculantus had the highest arscobic acid content of 603±64.1 mg/100 g edible dry plant material followed by Rosa rubiginosa (500.8±48.8 mg/100 g). The two plants had IC50 of 10.7±0.2 µg/mL and 47.8±0.2 µg/mL for DPPH inhibition, respectively. Forty percent (40%) (n=30) of the edible wild plants had significant (p<0.01) total antioxidant activity (IC50<60 µg/mL) and high ascorbic acid content (>200 mg/100 g). Nasturtium officinale reported the highest yield for soluble fibre (25%) while Hypoxis hirsute had the highest total dietary fibre content (7.3%). Rorippa nudiuscula enhanced the growth of B. animalis significantly (p=0.001), 8-fold more than inulin. Chenopodium album and Urtica dioica stimulated the growth of L. rhamnosus significantly (p=0.0001) than inulin, respectfully, while Tragopogon porrifolius significantly (p=0.0001) stimulated the growth of L. acidophilus than inulin. It was concluded that the investigated edible wild plants from southern Africa have antioxidant and prebiotic properties that may be beneficial to human health.

Depth Analysis

Objectives: The current study aimed to measure the antioxidant and antibacterial activities of 25 wild Palestinian edible plants, which were subjected to extraction by polar and non-polar solvents. Correlations between free radical scavenging activity and antibacterial activity of the extracts were assessed for both polar and non-polar fractions. Materials: Twenty-five wild edible plant species that are frequently consumed by people in Palestine (mainly in a rural area) were examined. Among them, 10 plant species were among those with the highest mean cultural importance values, according to an ethnobotanical survey that was conducted in the West Bank, Palestine, a few years ago. Method: The protocol of the DPPH assay for testing free-radical scavenging was utilized for determining EC50 values, while microdilution tests were conducted to determine the 50% inhibitory concentration (IC50) of the extracts for the microorganism Staphylococcus mutans. Results and Discussion: Eight extracts (non-polar fractions) were found to possess an antibacterial IC50 of less than 20 ppm, such as Foeniculum vulgare, Salvia palaestinafruticose, Micromeria fruticose, Trigonella foenum-graecum, Cichorium pumilum jacq, Salvia hierosolymitana boiss, Ruta chalepensis, and Chrysanthemum coronarium. The polar fractions possess higher antioxidant activity, while non-polar fraction possess higher antibacterial activity. Looking at all the results together can deceive and lead to the conclusion that there is no correlation between antibacterial activity against S. mutans and free radical scavenging (R2 equals 0.0538). However, in-depth analysis revealed that non-polar plant extracts with an EC50 of free radical scavenging ≤100 ppm have a four-fold order of enrichment toward more activity against S. mutans. These findings are of high importance for screening projects. A four-fold order of enrichment could save plenty of time and many in screening projects. The antibacterial active extracts marked by low-medium free radical scavenging might act through a mechanism of action other than that of highly active, free radical scavenging extracts. Conclusion: The screening of antioxidant and antimicrobial activity performed on 25 selected wild plant extracts revealed a satisfactory free radical scavenging and antimicrobial potential that could be of value in the management of oxidative stress. Further studies are recommended to explore novel and highly active natural antibacterial products.

Broad bean plants (Vicia faba L.) were cultivated in two field experiments at the Experimental Station of the Faculty of Environmental Agricultural Sciences, Arish University, North Sinai, Egypt, during 2018/2019 and 2019/2020 seasons under North Sinai condition, to study the effect of soil application of some biofertilizers and foliar spray with some wild plant extracts on broad bean plants. Biofertilizer treatments contained combination of Arbuscular Mycorrhizal Fungi (AMF) + Trichoderma harzianum + Rhizobium leguminosarum. Three wild plant extracts treatments; i.e., Qeysoom Gebeli (Achillea fragrantissima L.), Harmal (Peganum harmala L.) and Mitnaan (Thymelaea hirsute L.) were sprayed on plants. Treatments were arranged in a randomized complete block design with three replicates in split plot system. The results indicated that biofertilizers had significant effected of all studied traits in both seasons. Foliar spraying of Thymelaea hirsute extract had the highest stimulation effects on spores count, root colonization, mycorrhizal status, and weight of non-active nodules, broad bean plant growth characters; i.e. stem length, number of branches per plant, leaf area, and shoot fresh and dry weight as well as both of fresh and dry weight of roots. Both of Thymelaea hirsute and Achillea fragrantissima extracts combined with biofertilizer treatment had significant effects on yield and its components (pod length, number of pods per plant, average pod weight total yield per plant, and weight of seeds per pod) in both seasons. The combination between Thymelaea hirsute and biofertilizer was the superior interaction treatment of this study.

This study evaluated the antimutagenic and cytotoxic effects of some plants growing in Mongolia and plants were selected on the basis of their traditional use in various diseases. Over the past years numbers of cancer incidences are increasing in Mongolia. There are accounted several reasons, in particular the use of less guaranteed imported food, heavy air pollution, environmental contamination and low life quality of the population. Therefore, we attempted to search antimutagenic activity among plants from the Mongolian flora and possibility of their use for preventing and treating cancer cases. The study might promote the way to fight with cancer, if we can find antimutagenic active compounds from natural crude drugs, including medicinal plants.We have examined the antimutagenic and cytotoxic effects of 20 samples, which prepared from different parts of 10 plants species. The antimutagenic and cytotoxic tests were performed as described by Ames. The bacteria used in the test are a strain of Salmonella typhimurium TA1537, and using 9-aminoacridine as direct mutagen.From the 20 plant extracts studied, extracts of Achnatherum splendens Trin. (aerial parts), Cynoglossum divaricatum Steph. (roots, stems), Juniperus sibirica Burgsd. (leaf, stem) strongly inhibited mutagenicity of 9-aminoacridine and their inhibition activity was 49.7%, 41.5%, 61.5%, 40% and 43% respectively. All plant extracts have not any cytotoxic effect on Salmonella typhimurium TA1537.From the high active plants Juniperus sibirica Burgsd. (aerial parts) which was selected for further detailed study 3 pure active compounds as JS-1, JS-2 and JS-3 were isolated. The compound JS-3 showed the high (55%) antimutagenic activity and its molecular structure was determined as cetyl alcohol or hexadecanol-1 according to its physical and chemical characteristics as well as 1H-NMR and 13C-NMR spectroscopy analysis.We have revealed that the availability of plants possessing antimutagenic activity among the Mongolian flora. Consequently, it is needed further detailed study of active plants, isolation and identification of active pure compounds, as well as possible application of the active plant products in the medicinal practice.
