Abstract

The present study evaluated and compared the chemical compositions of the leaves and seeds of Persea americana. Chemical analyses of the extracts were done using standard methods. Tannins, flavonoids, alkaloids, glycosides, terpenoids, saponins and steroids were present in the leaf and seed samples. Flavonoid, terpenoid and glycoside concentrations were significantly (P<0.05) higher in the leaves while alkaloids, saponins, tannins and steroids did not differ in both extracts. Percentage carbohydrate was significantly (P<0.05) higher in the seeds while the leaves had higher percentage protein and crude fat. No significant (P>0.05) difference in percentage moisture, fibre and ash were recorded in both samples. Thiamin, riboflavin, pyridoxine, cyanocobalamine, ascorbic acid, ergocalciferol and tocopherol were significantly (P<0.05) higher in the seeds while the leaves contained significantly (P<0.05) higher concentration of retinol. The concentrations of niacin and biotin were not significantly different in the leaf and seed samples. The leaves contained significantly (P<0.05) higher amounts of iron (Fe), zinc (Zn) and phosphorus (P). The seeds recorded significantly (P<0.05) higher amount of potassium (K) while the concentrations of calcium (Ca), magnesium (Mg), sodium (Na), and copper (Cu) did not differ significantly (P>0.05) in the leaves and seeds. Lead (Pb) was not detected in both samples. The study shows that the leaves and seeds of Persea americana could be medicinally and nutritionally useful due to their rich phytochemical, proximate, vitamin and mineral compositions.
