This study is carried out for the research of antimicrobial and antioxidant effects of Gypsophila. perfoliata L. var. perfoliata, G. perfoliata L. var. araratica Kit Tan, G. pilosa Huds. and G. osmangaziensis Ataslar & Ocak plant extracts. The species of genius Gypsophila L. which are used in this study are collected from two different lokalities. The antimicrobial effects of plants extracts are researched against bacteria Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Salmonella typhimurium, Staphylococcus epidermidis, Staphylococcus aureus and against fungi Aspergillus niger, Aspergillus fumigatus, Fusarium solani. Antimicrobial activities were examined using disc diffusion technique. The minimum inhibitory concentrations (MIC) was determined by the micro dilution method. Phytochemical scans are made to examine the types of plant secondary metabolites. Free radical scavenging effect of plant species are made with DPPH. Petroleum ether and ethyl acetate extracts of G. pilosa and methanol extracts of G. perfoliata var. perfoliata against P. vulgaris are formed high inhibition zone. The results show that the three extracts (1A, 1C and 4B) produced favorable results against P. vulgaris microorganism with MIC values between 230.4 and 460.9 mu g/mL.
