ABSTRACT This study on phytochemical analysis of tiger nut (Cyperus esculentus) seed was carried out using standard analytical methods. The result of the study revealed the following; Saponin (2.776±0.049 mg/100g), Alkaloid (1.502±0.014 mg/100g), Flavonoid (4.280±0.042 mg/100g), Tannin (0.727±0.012 mg/100g) and HCN (0.473±0.054 mg/100g). most of the phytochemicals were present in small amount when compared with […]

ABSTRACT Fresh ripe fruit of Dennettia tripetala was obtained from Etinan L.G.A of Akwa Ibom State. The fresh fruit were separated, washed and sliced. They were sundried for days after which the were ground to powder form prior phytochemical analysis. The result obtained showed that flavonoids, tannins, saponins, alkaloids and HCN are present (+) the

ABSTRACT The aim of this study was to determine the anti-nutritional factors of Heinsia crinita leaves. The sample was analyzed using standard analytical methods. The result of the study revealed the following; HCN (1.240±0.071 mg/100g), Tannin (07.125±0.078 mg/100g), Phytate (3.590±0.042 mg/100g) and oxalate (0.095±0.049 mg/100g). All the anti-nutrients detected were below the lethal dose. This

ABSTRACT The research work was on comparative analysis of vitamins contained in ripe and unripe Dinnetia tripetala fruit. The vitamins A and B was estimated spectrophotochemically. The analysis of vitamins A in ripe and unripe Dinnetia tripetala was 6.59±0.09 and 7.26±0.05. The vitamin B1 contained in ripe Dinnettia tripetala was 1.26±0.02 and unripe was 3.09±0.01.
