Abstract

This work is designed to enrich the available scientific data on the phytochemistry and nutrient content of N. laevis leaves. The method of cold maceration was used in the extraction by serial exhaustive extraction method. The phytochemical screening of Newbouldia laevis was using through controlled experiment. Qualitative phytochemical screening and proximate analyses of Newbouldia laevis was studied using extracts of n-hexane, ethyl acetate, acetone and methanol which were obtained extract from powdered plant part. The extracts were subjected to qualitative phytochemical screening using standard procedure and the results shows that all the phytochemicals screened for were revealed in various leaf extracts. Alkaloids and flavonoids are present in all the extracts except ethyl acetate that did not show the presence of alkaloids. Only phlobatannins and tannins were absent in all the extract, steroid is present only in acetone. The proximate analysis revealed the nutritional composition of Newbouldia laevis to be 6.03% of moisture, 7.96% of ash, 9.81% of crude protein, 16.50% of fat, 33.40%. The diversity of phytochemical present suggested that N. laevis could serve as a source of drugs.
