Phytochemical investigation was carried out on the crude methanol and aqueous extracts of the
seeds of
Harpullia arborea
(Blanco) Radlk. (Sapindaceae). The antimicrobial activity of the extract was tested
against standard strains and clinical isolates of some bacteria using the disc diffusion method. Preliminary
phytochemical studies revealed the presence of glycosides, steroids, saponins and resins as the chemical class present
in the extracts. The extracts showed inhibitory activity against clinical isolates of Bacillus subtilis,
Salmonella typhi
,
Pseudomonas aeruginosa
,
Escherichia coli
and
Proteus vulgaris
. The results showed that the methanol extract was
more potent than the aqueous extract @ JASEM
