Abstract

Sanseviera liberica check for this species in other resources is used in Nigerian folk medicine for the treatment of asthma, abdominal pain, diarrhea, wounds of the foot, gonorrhea, snake bites etc. Some of these diseases are caused by pathogenic bacteria. To validate the trado-medical applications of S. liberica, an investigation of the phytochemical and antimicrobial properties of the methanol and n – hexane extracts was conducted. Phytochemical screening revealed the presence of tannins, flavonoids, saponins, reducing sugars and carbohydrates in both extracts. Alkaloids were present only in the methanol extract. Glycosides, terpenoids and steroids were absent in both extracts. The proximate analysis of S. liberica showed total ash value of 6.0 %, acid insoluble ash of 1.10 %, alcohol extractive value of 6.80 %, water extractive value of 5.20 % and moisture content of 14.50 %.The broth microdilution technique was used to evaluate the antimicrobial activities of both the methanol and n – hexane extracts of S. liberica. Results showed that Psuedomonas aureginosa check for this species in other resources , Streptococci pyrognase check for this species in other resources and Staphylococcus aureus check for this species in other resources were sensitive to the methanol extract while Candida albicans check for this species in other resources , Klebsiella pneumonia check for this species in other resources , Salmonella typhii check for this species in other resources , Baccilus subtilis check for this species in other resources and Escherischia coli check for this species in other resources were not sensitive. All the eight microorganisms involved in the antimicrobial assay were not sensitive to the n-hexane extract.
