Abstract

Evaluation of phytochemicals and antioxidants levels were conducted in the dry leaves of aqueous and methanolic extracts of  Vernonia amygdalina, Carica papaya, Persea americana and Cnidosculous aconitifolius.  Methanolic extract was found to contain the highest value for sterols, tannin, saponin, flavonoids, alkaloids, phenols, phlobatannins, anthraquinones, triterpenes and cardiac glycosides.  However, oxalate and phytate were absent in both aqueous and methanolic extracts.  The results also showed that leave extracts of these plants are good sources of antioxidants as revealed by the presence of these antioxidants in these plant but with highest values in the methanolic extract.  Conclusively, the presence of some of these phytochemicals and antioxidants explained the hypotensive action of these plants in cardiovascular diseases.
