“…from the families Solanaceae, Basellaceae, and Gnetaceae, respectively. These uncommon vegetable types of medicinal plants are only available in local markets and rural areas [3,4], which explains the limited research data available. They are used traditionally for the treatment of diabetes, body pains, wounds, arthritis, fever, cancer, ulcer, and epilepsy and have been reported to display antioxidant, antimicrobial, anti-inflammatory, anticancer, wound healing, and antiulcer activities [5][6][7][8][9][10].…”

Biological activities of six under-utilized medicinal leafy vegetable plants indigenous to Africa, i.e., Basella alba, Crassocephalum rubens, Gnetum africanum, Launaea taraxacifolia, Solanecio biafrae, and Solanum macrocarpon, were investigated via two independent techniques. The total phenolic content (TPC) was determined, and six microtiter plate assays were applied after extraction and fractionation. Three were antioxidant in vitro assays, i.e., ferric reducing antioxidant power (FRAP), cupric reduction antioxidant capacity (CUPRAC), and 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging, and the others were enzyme (acetylcholinesterase, butyrylcholinesterase, and tyrosinase) inhibition assays. The highest TPC and antioxidant activity from all the methods were obtained from polar and medium polar fractions of C. rubens, S. biafrae, and S. macrocarpon. The highest acetyl- and butyrylcholinesterase inhibition was exhibited by polar fractions of S. biafrae, C. rubens, and L. taraxacifolia, the latter comparable to galantamine. The highest tyrosinase inhibition was observed in the n-butanol fraction of C. rubens and ethyl acetate fraction of S. biafrae. In vitro assay results of the different extracts and fractions were mostly in agreement with the bioactivity profiling via high-performance thin-layer chromatography–multi-imaging–effect-directed analysis, exploiting nine different planar assays. Several separated compounds of the plant extracts showed antioxidant, α-glucosidase, α-amylase, acetyl- and butyrylcholinesterase-inhibiting, Gram-positive/-negative antimicrobial, cytotoxic, and genotoxic activities. A prominent apolar bioactive compound zone was tentatively assigned to fatty acids, in particular linolenic acid, via electrospray ionization high-resolution mass spectrometry. The detected antioxidant, antimicrobial, antidiabetic, anticholinesterase, cytotoxic, and genotoxic potentials of these vegetable plants, in particular C. rubens, S. biafrae, and S. macrocarpon, may validate some of their ethnomedicinal uses.

“…Eventually, they get stored up across the food chain, in hazardous amounts in the human body (Li et Vegetables are common sources of vitamins and minerals which are consumed for healthy living in Nigeria. Indigenous vegetables such as Celosia argentea, Solanum macrocarpon, Solanum nigrum, Amaranthus, viridis, Talinum triangulare, Senecio biafrae, Crassocephalum cecropidoides, etc, represent a cheap and readily available source of important classes of food and are usually consumed alongside staple diets (Ogunrotimi et al 2018) Amaranthus viridis for instance, is a good source of avonoids, phenolics, antioxidants with large medicinal and pharmacological effects. It is rich in dietary ber, proteins, carbohydrates and essential elements like Cu, P, Zn, Mg, Ca, Na, etc.…”

Conversion of dumpsites to farm lands in several communities is a usual practice in Nigeria. Wastes accumulate heavy metals in a variety of forms. This study assessed the concentration, degrees of contamination and attendant health risk of heavy metals (HMs); using two major indigenous vegetables (Amaranthus viridis and Talinum triangulare) grown on ve major dumpsites in Lagos state. After wet digestion, the mean concentrations of the HMs in the vegetable samples were evaluated using Atomic Absorption Spectrophotometer (AAS). Daily intake of Metals (DIM), tangent hazard quotient (THQ) and hazard index (HI) biomathematics were employed in the assessment of non-carcinogenic health risk. Incremental Lifetime Cancer Risk (ILCR) assessment was used to assess Carcinogenicity. HM concentrations detected fell within the following ranges: (0.59 to 0.37), (0.07 to 1.36), (0.30 to 2.21), (0.00 to 0.03) and (0.00 to 0.04) mg/kg; for zinc (Zn), Lead (Pb), Iron (Fe), cadmium (Cd), and chromium (Cr), respectively. Low to moderate variability and statistically signi cant differences were seen in the concentration of HMs in vegetables, (p<0.05). At Ikorodu, Pb concentration was above the world Health Organization (WHO) permissible range and has the highest contamination factor. DIM and THQ for Fe and Pb were above threshold values (>1); HI values for the vegetables exceeded WHO normal range (>1), except Abule-Egba samples. These values reveal great health risk from consumption of vegetables from four major sites. ILCR values for 43.3% of the samples were above the WHO (10 -6 ) limits, indicating high risk of carcinogenicity over a life time of exposure.
