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.

Background:: Mushrooms are deemed as a special delicacy in many countries. They are considered an important cuisine due to their bioactive ingredients and possible health benefits. Methods: Herein, we measured selected biological properties of methanol extracts of Pleurotus citrinopileatus and Boletus edulis fruiting bodies including; in vitro antimicrobial activity, anti-α- glucosidase activity, antioxidant activity, anti-lipase activity and cytotoxic activity against different cancer cells and normal cells. Results: B. edulis methanol extracts showed high antimicrobial and anti-α-glucosidase activity. In contrast, P. citrinopileatus methanol extracts showed superior antioxidant activity indicated by (1,1- diphenyl-2-picrylhydrazyl) DPPH radical scavenging with half maximal inhibitory concentration of IC50 37.4 µg/ml, anti-lipase activities with IC50 65.2 µg/ml and high cytotoxicity activity against HepG2 and HeLa cell lines with IC50 22.8 and 36.7 µg/ml, respectively. Flow cytometric analysis of the cell cycle was used to show apoptotic effects of methanol extracts against HepG2 and HeLa cells. Conclusion: P. citrinopileatus and B. edulis methanolic extracts appear to contain biologically active compounds that might be used to treat some common human diseases.

This study compared the mineral content and bioactive properties of flowers and fruit coming from wild elderberry plants with those of flowers and fruit harvested from elderberry cultivars grown in an orchard. Elderberry fruit and flowers were analyzed for the content of selected minerals, phenolic compounds, and anthocyanins, as well as for antioxidant activity. Mineral content was determined by the atomic absorption spectrometry method, while antioxidant activity and the content of polyphenols and anthocyanins were determined by spectrophotometric methods. Flowers were found to contain more total ash and much higher content of most of minerals, except magnesium which was present in high concentrations in fruit. Fruit showed significantly higher antioxidant activity than flowers, whereas the total phenolic content varied depending on the growing location or cultivar. The material obtained from selected cultivars growing in an orchard had higher antioxidant activity and polyphenol and anthocyanin content than the material obtained from wild plants. Fruit of the ”Haschberg” cultivar and flowers of the ”Sampo” cultivar had the best bioactive properties of the studied samples.

Antioxidant Effects

Objective: Prasman (Ayapana triplinervis [Vahl]) is a plant that can eliminate free radicals through its antioxidant effects. However, little research hasbeen conducted to explore the antioxidant activity of the plant.Methods: A. triplinervis (Vahl) leaves, which were determined by the Indonesian Institute of Sciences (LIPI) Bogor, were used in this study. Meanwhile,extraction was performed using n-hexane, ethyl acetate, and methanol as the solvents. Based on the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay usinga UV–visible spectrophotometer and based on ferric reducing antioxidant power (FRAP) assay using a microplate reader.Results: Based on the DPPH assay using a UV–visible spectrophotometer, n-hexane, ethyl acetate, and methanol extracts with a final concentrationof 25 μg/mL inhibited DPPH radical production by 38.91, 51.03, and 54.06%, respectively. Using the percent inhibition, the IC50 for the ethyl acetateand methanol extracts were 28.71 and 23.472 μg/mL, respectively. Based on FRAP assay using a microplate reader, the n-hexane, ethyl acetate, andmethanol extracts had ferrous equivalent antioxidant capacity values of 460, 828.99, and 940.22 μmol/g, respectively. The methanol extract had thegreatest antioxidant activity. The ethyl acetate and methanol extracts at the initial concentrations contained total phenol levels of 12.06 and 42.11 mgGAE/g extract, respectively, as well as total flavonoid levels of 3.24 and 3.41 mg QE/g extract, respectively.Conclusion: Based on the determination of phenol and flavonoid levels, the methanol extract had the greatest antioxidant effects.

In response to increased popularity and greater demand for medicinal plants, a number of conservation groups are recommending that wild medicinal plants be brought into cultivation systems. We collected four medicinal herbsCichorium pumilum, Eryngium creticum,Pistacia palaestinaandTeucrium poliumused in traditional Arab medicine for greenhouse cultivation to assess the effects of different fertilization regimes on their growth and antioxidant activity. Wild seedlings were collected and fertilized with either 100% Hoagland solution, 50% Hoagland solution, 20% Hoagland solution or irrigated with tap water. Plant height was measured and the number of green leaves and branches counted weekly. Thereafter, the aboveground parts of plants were harvested for preparing a water-soluble powder extracts of which antioxidant activity was measured by their ability to suppress the oxidation of β-carotene. Of the fertilization regimes, we found either 20 or 50% Hoagland solution produced the most consistent response of the plant growth parameters. All powders prepared from the four wild growing plants inhibited oxidation of β-carotene. Increasing the amount of fertilizer caused a significant concentration-dependent increase in antioxidant activity of the cultivatedT. poliumcompared with the wild type. In contrast, increasing the amount of fertilizer caused a significant concentration-dependent reduction in the antioxidant activity of powders prepared from the cultivatedE. creticumwhen compared with wild plants. Our results showed that cultivation success should not rely solely on parameters of growth but should incorporate assessment related to indices of therapeutic potential.
