ABSTRACT

A comparative study of the chemical compositions of Moringa tea, Lipton tea,Top tea and the leaves of Dialium guineense and Moringa o/eifera was carried out. Results of the phytochemical compositions revealed that Moringa oleifera leaves contained the highest amount of alkaloids (1.31±0.042mg/ 100g), saponins (1.25±40.014 mg/l OOg),flavonoids ( 1.07±0.02 I mg/I OOg), and HCN (3.84±0.007mg/ I OOg),while lipton tea contained the least alkaloids (0.17±0.01 mg/I OOg), flavonoids (0.66±0.028 mg/I 00g),HCN (0.1740.021mg/100g). Top tea contained the highest tannins ( 1.37±0.01 4mg/ I OOg) while Dialium guineense leaves contained the least tannins (1.07±0.014mg/ 1 00g).Results of the vitamin compositions showed that Moringa oleifera leaves contained the highest amount of vitamin A (3.75±0.042mg/100g), while top tea contained the least (1.19±0.014mg/l00g). Dialium guineense leaves contained the highest ascorbic acid (26.28±0.735mg/l OOg), while top tea contained the least (5.28±0.028mg/l 00g). Moringa oleifera leaves contained the highest amount of vitamin E (6.3l±0.014mg/100g) while Dialium guineense leaves contained the least (2.52±40.106mg/100g).The results of micro and macronutrients revealed that Moringa oleifera leaves contained the highest nutrients, Zn( 1.85±0.0 I 4mg/ I OOg), Fe(2. 1 7±0.01 4mg/ I OOg), Na( 68.37±0.106mg/ I 00g), Ca(l 06.87 ± 0.183mg/l00g), K(128.37±0.52 mg/100g),P(43.69 ±0.127mg/100g),Mg(53.53 ±0.098mg/100g) while top tea contained the least amounts of Zn(0.48 ±0.000mg /100g), Na(16.46 ±0.056 mg /100g), Ca(21.41±0.091mg/l00g) and lipton tea contained the least amounts or Fe(0.77 ±0.014mg /100g), K(33.66 ±0.735mg /100g),P(14.2940.014mg/100g)and Dialium guineense leaves contained the least amounts of Mg(28.82 ±0.593mg /I OOg).Na:K of Moringa tea(0.72:lmg/IOOg), Lipton tea(0.61:1mg/l00g),Moringa oleifera leaves (0.53:lmg /lOOg),Top tea(0.46: I mg/I OOg) and Dialium guineense leaves (0.39: I mg/I OOg).Ca:Mg of Dialium guineense ,leaves (2.72: 1mg /1 00g),Moringa oleifera leaves(2.00: I mg/1 00g),Lipton tea(0.64: I mg/ l 00g),Moringa tea(0.54: I mg/ l 00g) and Top tea(0.49: I mg/I OOg).Ca:P of Moringa oleifera leaves (2.45:lmg/IOOg), Dialium gttineense leaves (2.22:lmg/lOOg), Lipton tea (1.73: 1mg/100g), Moringa tea( 1.38: I mg/100g) and Top tea( 1.28: i mg/1 OOg).
