“…America but now cultivated throughout the tropics especially were the climate is suitable for the growth of the plant. Psidium guajava is a medium sized tree with evergreen, opposite, aromatic short-petioled leaves [13]. Psidium guajava (Guava) is a phytotherapic plant used in traditional medicine that is believed by the indigenous group to posses' active components that help to treat and manage several diseases [14].…”

“…Fresh and pure clinical isolates of S. aureus, E. coli, and S. faecalis were obtained from Department of Medical Microbiology, General Hospital Mubi in Adamawa State,Nigeria and were used for the experiment. The identification and characterization of the isolates was carried out by using three methods, namely gram staining, cultural characterization using selective or indicative media and biochemical characterization with reference to Cheesbrough [13]. The pure isolates of each of the test organisms were inoculated in sterile slants containing Nutrient agar and transported to the Department of Chemistry, ADSU Mubi and refrigerated at 4ºC before use.…”

Psidium Guajava (Guava) and Carica Papaya leaves which have some ethnomedicinal applications were investigated. Phytochemical screening of their leaves revealed the presence of flavonoids, saponins, terpenoids, steroids, tannins and glycosides. Antimicrobial screening of the crude ethanolic extracts showed activity against Staphylococcus aureus, Streptococcus faecalis, and Escherichia coli. The minimum inhibitory concentration (MIC) for P. gujava on the organism was found to be 5.00 mg/ml against S. aureus, E. coli and S. faecalis, while that of C. papaya leaves is 10.00 mg/ml against S. aureus, E. coli and 8.00 mg/ml against S. faecalis respectively. C. papaya ethanolic extract showed more active inhibition against S. aureus with mean zone inhibition of 9.54 ± 0.03. P. gujava ethanolic extract has more active inhibition against E. coli with antibacterial activity with mean zone of inhibition of 10.44±0.02 and S. faecalis with mean zone of inhibition of 6.72 ± 0.01 respectively. This study showed that the leaves extract of these plants are good sources of bioactive compounds. Demonstration of antibacterial activity against the test isolates is an indication that there is possibility of sourcing alternative antibiotic substances in these plants for the production of newer antibacterial agents. These plants therefore, could be an important source of medicine for the treatment of various diseases.

The study was aimed to investigate the phytochemical constituents and antibacterial activity of Senna siamea leaves extracts against some pathogen bacteria. Aqueous and ethanol extracts from Senna siamea leaves were prepared, screened for phytochemical analysis and tested for its antibacterial activity against 6 pathogenic bacteria (Klebsiella pneumoneae, Salmonella typhi, Shigella spp, Escherichia coli, and Pseudomonas aeruginosa) recovered from stool sample of patients attending Murtala Muhammad Specialist Hospital Kano. Phytochemical screening of the extracts showed that Senna siamea extract contain Alkaloid, Anthraquinone, saponin, tannin, phenol, steroid, flavonoid, terpenoid and glycosides. Statistical analysis of the result showed that highest antibacterial activity was recorded in ethanol extract with average zone of inhibition of 14.12±1.51 mm among the isolates while aqueous extracts recorded an average zone of inhibition of 12.00±1.06 mm. Based on the susceptibility of the organisms to the extracts, E. coli was found to be the highest susceptible organisms with average zone of inhibition of 14.29±1.12 mm, followed S. aureus(13.61±1.23mm), Salmonella typhi(13.56±1.89mm), Shigella (13.22±1.41mm), Pseudomonas(12.36±1.38mm) while least average zone of inhibition is shown by Klebsiella(11.33±0.80mm). The MIC and MBC of the extracts ranges from 3.125 to 50mg/ ml There is no significant different on the susceptibility of the organisms against the extracts at p<0.05. The results of the present study have supported the therapeutic potential of Senna siamea and its use as medicinal plant.
