Abstract

ABSTRACT This study identified the various chemical compounds present in Dracaena trifasciata leaves extracts found in Sokoto region and also evaluate its antibacterial activity for the possibility of using them in the development of new antibiotics to reduce cost of health care and mortality rate due to resistance of bacteria to already developed drugs. The Dracaena trifaciata leaves were found to have a percentage moisture content of 62.65 %. Cool extraction method was adopted to extract the leaves of Dracaena trifasciata using ethanol solvent and also standard methods were used to assess the antibacterial activity of the extracts. The result obtained from solvent extraction of Dracaena trifasciata leaves revealed the mass of extract to be 8.20g with percentage yield of 66.67%. The phytochemical screening of the leaves extracts revealed the presence of alkaloids, saponins, steroids, tannins, flavonoids and cardiac glycoside while anthraquinones were not detected. The results of the antibacterial studies revealed that the fractions has activity on the selected bacteria strain (S. aureus, E. coli , S. typhi and B.subtile) with zone of inhibition that ranges between 1-13 mm. these results shows that the leaves of Dracaena trifasciata has a potential for the development of new antibiotic drugs.
