Waltheria indica is said to be one of the medicines used for treatment of diseases such as diarrhea, malaria, fever etc. in most part of the world especially Hawaii. It is against this background that the plant was used to check for phytochemicak compositions and antimicrobial activity. the phytochemical screening carried out indicates the presence of saponin, tannin, flavotannin, terpenoid, and volatile oils in both methanolic and aqueous extracts. Alkanoid and glycsides were absent in both methanolic and aqeous extract of the leaf. Anthraquinone is only absent in the methanolic extract but present in the aqeous extract of the leaf. the leaf extract showed significantly varying inhibitory activities against the test organisms as evidenced by the zone of inhibition (p>0.5). The leaf extract was found to be active against all test organisms but but the degree varies from one test organism to another. The thin layer chromathography shows different pattern of elution and this indicates the variation of the polar and non polar active biological compounds found in the extract.
