Phytochemical screening to determine the presence and concentration of tannins, saponins, alkaloids, flavonoids, sterols and cardiac glycosides in Persea americana was carried out. The sample was prepared by cutting the seed into small pieces, drying and grinding with Thomas Willey milling machine. The ground sample was stored in an airtight container for analysis. The presence of alkaloid was determined by Wagner’s test, flavonoid by ferric chloride test, tannin by acid test, saponin by emulsion test and cardiac glycoside by glacial acetic acid test. Quantitative determination of some of the phytochemicals was also carried out using standard methods. Result for qualitative analysis shows that alkaloids, flavonoids, saponins, tannins and cardiac glycosides were present in P.american and sterols were absent . The quantitative result shows that alkaloid has the highest percentage of concentration (21.54%), followed by saponin (8.10%), flavonoid (6.97%), cardiac glycoside (6.94%) and tannin has the least percentage concentration (1.45%) .

are a large group of plant derived compound hypothesized to be
responsible for much of the disease protection conferred from diets high

tea and wine (Hollman, 2005). They are biologically naturally occurring
chemical compounds found in plants . They protect plants from disease
