An Assessment of the Antimicrobial Properties of Extracts of Various Polarities from Chasmanthera dependens, Emilia coccinea and Cuscuta australis, Herbal Medications for Eye Diseases
W. Okiei, M. Ogunlesi and M.A. Ademoye

Abstract:
An assessment of the antimicrobial properties of extracts from the stem of Chasmantera dependens, the leaves of Emilia coccinea and the whole plant of Cuscuta australis plants which are used in the management of eye diseases in Nigeria is presented. The 50% methanol extracts were extracted sequentially with hexane, ethyl acetate and butanol to give fractions of various polarities which were tested for antimicrobial properties against various microorganisms including fungal yeast, Gram-positive and Gram-negative bacteria, namely Candida albicans, Bacillus subtillis, Citrobacter sp., Enterococcus faecalis, Escherichia coli, Escherichia coli ATCC 25922, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella sp., Salmonella typhimurium, Serratia marcescens, Shigella flexnerii, Staphylococcus albus, Staphylococcus aureus and Staphylococcus aureus ATCC 2593. The hexane fractions of all the plants were not found to possess antimicrobial activity on any of the microorganisms tested. The ethyl acetate fractions of C. dependens and E. coccinea were found to possess significant antimicrobial activity against several of the microorganisms while that of C. australis was active against only three of the microorganisms. The butanol fraction of E. coccinea showed significant antimicrobial activity against several of the microorganisms while those of C. dependens and C. australis were respectively active against only two and three of the microorganisms. The results support the use of E. coccinea as a potent anti-diarrhoeal agent and the uses of the plants as antimicrobials in herbal medicine.
