In this study, the antimicrobial activities of methanolic extracts and latex of some Euphorbia
species used for medical purposes in Turkey were investigated. The extracts of Euphorbia aleppica
, Euphorbia szovitsii
Fisch.&Mey. var. harputensis Aznav. ex M. S. Khan, Euphorbia falcata
, Euphorbia denticulata
Lam., Euphorbia macroclada
Boiss., Euphorbia cheiradenia
Boiss.&Hohen, Euphorbia virgata
Waldst.&Kit., Euphorbia petiolata
Banks&Sol. were prepared with methanol. The antimicrobial activities of these extracts were examined on test microorganisms as follows: Staphylococcus aureus
COWAN 1, Bacillus megaterium
DSM 32, Proteus vulgaris
FMC 1, Klebsiella pneumonia
FMC 5, Escherichia coli
ATCC 25922, Pseudomonas aeruginosa
DSM 50071, Candida albicans
FMC 17, Candida glabrata
ATCC 66032, Epidermophyton sp.
and Trichophyton sp.
by the disc diffusion methods and well agar method. The MIC values of extracts were determined according to the broth microdulitions method. Results indicated that extracts of Euphorbia species inhibited the growth of tested microorganisms in the different ratio. Also, the MIC values of extracts were determined as 31,2-1000 μg.
