Abstract
Chewing sticks are widely used in Nigeria for dental and oral hygiene. In-vitro susceptibility test was done with aqueous extracts of Distemonanthus benthamianus on three test isolates (Staphylococcus aureus ATCC 8043, Saccharomyces cerevisiae ATCC 2601 and Pseudomonas aeruginosa ATCC 27853) using agar well difffusion technique. Staphylococcus aureus ATCC 8043 produced highest zone of inhibition to water extract of the plant with a value of 35.0 mm at 200 mg/ml. All organisms were susceptible to the ethanolic extract with Staphylococcus aureus ATCC 8043 and Saccharomyces cerevisiae ATCC 2601 exhibiting highest zone of inhibition with a range of 23.0-35.0 mm and 30.0-35.0 mm respectively. Phytochemical analysis of the plant revealed no significant difference in the concentration of alkaloids and saponin. Flavonoids, phenol, steroid and tanin were among the active priciples present in the plant.
