Preliminary phytochemical screening of the revealed the presence of tannins, flavonoids, alkaloids, terpenoids, steroids, saponin and cardiac glycosides. The anti-nutritional screening of the crude extract showed that the leaves of kenaf contain 4.98±0.21 mg/kg of tannins, 0.38±0.051 mg/kg of alkaloids, 3.480±0.61 mg/kg of oxalate and 4.34±0.16 mg/kg of phytate. The result of inhibition of DPPH by crude aqueous leaves extract of Hibiscus Cannabinus (Kenaf) showed that the crude extract had antioxidant activity of 67, 74, 85 and 95% at 30, 60, 120 and 240 µg/mL (Figure 4.1) compared to the positive standard antioxidant agent ascorbic acid which had a percentage inhibition of 98, 97, 98 and 99% at 30, 60, 120 and 240 µg/mL, this suggests that the plant possesses significant antioxidant activity which can counteract the oxidative damage associated diseases. However, anti-nutritional factors of the leaves of this plant were low which makes them be edible. Based on the results obtained in this study, it could be that the aqueous contain chemical constituents of pharmacological and nutritional significance. ...Preview Download Preview +Other Biochemistry project topics and materials you might be interested in»Phytochemical and nutritive composition of fluted pumpkin»Determination of ascorbic acid in selected fruits mango, orange and pineapple using spectro-photometric method»Comparative evaluation of heavy metal loads in some selected soft drinks in Owerri, Imo state»Antilipidemic effect of water (H2O) extract of desmodium velutinum leaves on albino Wistar rats»The effect of water extract of cola nitida pod on lipoprotein concentrations of albino Wistar rats»Preliminary investigation on effects of burantashi extract on lipoproteins of albino male and female whistar rats»The extraction of manganese (iv) ion from aqueous media using 1-phethyl-3-methyl pyrazolone-5»Nutritive value, anti-nutrient and mineral composition of cashew nut (Anacardium Occidentale)»Evaluation of the immunomodulatory effect of oral administration of the methanol extract of gongronema latifolium (utazi) in wistar albino rats»Comparative study on the free radical scavenging potential of turmeric and beetroot»Phytochemicals and minerals analysis of rosary pea (Abrus Precatorious leaves)»Determination of total petroleum hydrocarbons in Niger river»Qualitative phytochemical and gas chromatography mass spectrometry GCMS of Nhexane extracted leaves of sabicea calycina»Hydrogen peroxide scavenging activities and reducing power of various fruits juice in Yenagoa»Charges in the concentration of nitric oxide in the serum gills brain liver and kidney of clarias gariepinus exposed to glyphosatebased herbicide
