Launaea (Lactuca) taraxacifolia also known as wild (African) lettuce is anethno-pharmacologically significant plant of the Asteraceae family. The plant was carefully chosen for this study due to its extensive use in traditional herbal practices to treat a wide range of ailments. The extraction of the leaves for phytochemical screening was carried out by subjecting the air dried pulverized plant materials into trichloromethane, normal hexane, ethyl ethanoate and methanol solvents for a period of some days, followed by filtration and concentration. Qualitative phytochemical screening of the extracts of the above solvents revealed the presence of saponins, phenols, alkaloids, cardiac glycosides, terpenoids, tannins, plant steroids and flavonoids. Quantitative analysis of the phytochemicals showed that saponins occurred withthe greatest concentration of 4.26 ± 0.08 %, followed by cardiac glycosides with a concentration of 2.27 ± 0.02 %; while phenols had the least concentration of 0.13 ± 0.01%. The proximate analysis was carried out using the dried leaves and the results obtained revealed the presence of crude protein (38.40 ± 1.20 %), crude fibre (1.565 ± 0.08 %), crude fat (4.60 ± 0.04 %), crude ash (5.02 ± 0.070 %), moisture (14.91 ± 0.50) and available carbohydrates (35.50 ± 1.26 %). The calorific value of the leaves in gram per calories was estimated to be 337 ± 0.70. The extraction, purification, concentration, phytochemical screening and nutritional analysis were carried out at Post-graduates, chemistry and bio-chemistry laboratories, Michael Okpara University of Agriculture, Umudike, Abia State, Nigeria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
