Qualitative and quantitative phytochemical screening of ethanolic extract of Cyperus esculentus L. (Tiger-nut) was carried out to determine possible medicinal and nutritive properties. Cyperus esculentus has been in use by traditional medical practitioners for treating and preventing several ailments like erectile and heart dysfunctions, diabetes etc. Results of the study revealed the presence of some bioactive compounds such as alkaloid, flavonoid, steroid, tannin, glycoside, phenol, terpenoid, and saponin. Results obtained were as follow: the percentage yield of the extract 3.83%, alkaloid (1.47 ± 0.04mg/g), flavonoid (2.55 ± 0.20mg/g), saponin (0.93 ± 0.12mg/g), tannin (0.74 ± 0.05mg/g), glycoside (0.53 ± 0.66mg/g), steroid (0.19 ± 0.12mg/g), terpenoid (0.47 ± 0.03mg/g), and phenol (0.87 ± 0.03mg/g). Results indicated that flavonoid is highly present with the highest concentration compared to other phytochemicals. The presence of these phytochemicals in tiger nuts extract could be the reason tiger nuts are used as alternative in feeding farm animals and in the management of illnesses and diseases by local herbal medical practitioners.
