“…Similarly, Launaea taraxacifolia is locally believed (indigenous knowledge) to have, through simple and regular consumption as leafy vegetable, lactogenic, aphrodisiaque, antibiotic, and antimalaria properties, a wonderful blood pressure regulating and haemorrhoids treatment capacity [ 10 ]. Recently Obi [ 54 ] reported that leaves extract of the species has virucidal potential. Gill et al [ 55 ] reported that Citrullus lanatus has good antioxidant, anti-inflammatory, and analgesic potential and may be used as a future food medicine.…”

Many of the plant species that are cultivated for food across the world are neglected and underutilized. To assess their diversity in Benin and identify the priority species and establish their research needs, a survey was conducted in 50 villages distributed throughout the country. The study revealed 41 neglected and underutilized crop species (NUCS) among which 19 were identified as of priority base on 10 criteria among which included their extent and degree of consumption. Reasons for neglect vary with the producers and the agricultural technicians. Market surveys revealed that NUCS are important source of household incomes and substantially contribute to poverty reduction. Review of the literature available revealed that most of the species are rich in nutrients and have some proven medicinal values and the promotion of their use would help in combating malnutrition and improving the health status of the local populations. The knowledge gaps and research needs are immense on most of the species identified as no concrete scientific data is nationally available. In terms of research, almost all has to be done starting from basic ethnobotanical investigation. The results will help the scientists and students willing to conduct research on NUCS in Benin to better orient their research programs.

“…Senecio biafrae leaves, "Worowo" (Yoruba), are used by traditional practitioners to treat infertility in women (Lienou et al, 2010), heart problems (Ayodele, 2005), as well as serve as antihypertensive (Olowokudejo et al, 2008). Hypolipidaemic, hypoglycemic and antioxidants properties of Launaea taraxacifolia ̀ (Asteraceae) plant, Ẹfó ̣ yánrin (Yoruba), have also been reported (Dansi et al, 2008;Obi, 2011;Arawande et al, 2013).…”

This study identified, characterized and quantified the constituents of Basella alba Linn. var. alba, Crassocephalum crepidioides (Benth.) S. Moore, Launaea taraxacifolia Amin Ex. C. Jeffrey (Wild lettuce), Senecio biafrae Oliv. & Hiern. and Solanum nigrum L. var. virginicum (Black nightshade) leaves. Pulverised dried leaves (10 g each) of the vegetables were separately Soxhlet-extracted with 60 ml of n-hexane (99%). Aliquots (2 μl) of each concentrated plant extract were analysed using gas chromatography-mass spectrometry (GC-MS) technique. Forty-four (44) volatile compounds were identified from the analyses. Some of them are known antioxidants that are beneficial to health. Linoleic and palmitic acids were identified in leaves of B. alba (6.85% and 5.47%), C. crepidioides (14.88% and 27.22%) and L. taraxacifolia (20.78% and 42.35%) respectively. However, linoleic acid was absent in S. nigrum but linolenic acid (47.47%) was present as the major fatty acid. Oleic acid was identified respectively in leaves of B. alba (2.37%), C. crepidioides (6.86%) and L. taraxacifolia (7.14%). The information obtained from the GC-MS analysis of these wild underutilized vegetables can be used to develop novel drugs or food supplements.

“…Studies by Arawande et al (16) in Nigeria and Adinortey et al (17) in Ghana on the nutritional value and phytochemical characterization of L. taraxacifolia revealed that the extracts of its leaves are rich in potassium, calcium, magnesium, ascorbic acid, tannins, and flavonoids. Obi (18) and Arawande et al (16) reported that apart from use as food, L. taraxacifolia leaves are widely used in the form of infusion for the treatment of several diseases. They reported properties such as antiviral effects, decreased cholesterol levels, regulation of dyslipidaemia and regulation of blood pressure.…”

Background: Launaea taraxacifolia Willd (Asteraceae), commonly called wild lettuce, is a vegetable used as food and for various folkloric medicinal purposes and has been traditionally claimed to have protective effects against toxicants. Objective: This study assessed the potentials of Launaea taraxacifolia ethanol leaf (LTEL) extract pre-treatment in protecting the liver against carbon tetrachloride (CCl4)-induced toxic damage. Method: Adult Sprague-Dawley rats were pre-treated orally with LTEL extract (100 and 500 mg/kg) and silymarin at 50 mg/kg body weight for 7 days. A single dose of CCl4(3 ml/kg body weight) was administered to the rats orally. After the treatment period, serum levels of hepatic enzymes and antioxidants were assayed. Histopathological examination of liver sections was done. Results: Pre-treatment of rats with LTEL extract significantly (p<0.05) attenuated CCl4-induced acute increase in serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) levels compared to the group that received CCl 4 only. Reduced glutathione (GSH) was significantly (p<0.05) increased in the pre-treatment groups while malondialdehyde (MDA) was significantly (p<0.05) lower in these groups. No significant (p>0.05) change in catalase (CAT) and superoxide dismutase (SOD) was observed in all the groups. Histologic examination revealed the protective effect of silymarin and the extract on the hepatocyte architecture. Conclusion: This study suggests that Launaea taraxacifolia ethanol leaf extract possesses hepatoprotective property against CCl 4-induced liver injury through attenuation of oxidative stress.
