Cyperus rotundus L. (Cyperaceae) Uçucu Yağının Antibakteriyel Aktivitesi

Cyperus rotundus L'un yumru köklerinden su distilasyonuyla elde edilen uçucu yağinin antibakteriyel aktivitesi, bazı Gram (+) bakterilere (Bacillus cereus ATCC 11778, Sarcina lutea ATCC 9341, Staphylococcus aureus ATCC 6538, Streptococcus mutans NCTC 10449 ve Streptococcus salivarius Pasteur Ens. 55126) ve Gram (-) bakterilere (Escherichia coli ATCC 29998, Klebsiella pneumoniae NCTC 5046, Pseudomonas aeruginosa ATCC 27853, Salmonella cholerasuis ATCC 14028 ve Salmonella enteritidis ATCC 13076) karşı disk difuzyon metoduyla araştirildi. Antibakteriyel aktivite araştırma sonuçlari, Cyperus rotundus L'un uçucu yağinin Gram (+) bakterilere özellikle Staphylococcus aureus'a karşı etkili olduğunu, fakat Gram (-) bakterilere karşı ise hiçbir antibakteriyel etkisinin olmadigini göstermiştir

Abstract: The antibacterial activity of the essential oil from the tubers of Cyperus rotundus L., obtained by water-distillation, was investigated by the disc diffusion method against some Gram-positive bacteria (Bacillus cereus ATCC 11778, Sarcina lutea ATCC 9341, Staphylococcus aureus ATCC 6538, Streptococcus mutans NCTC 10449 and Streptococcus salivarius Pasteur Ens. 55126) and Gram-negative bacteria (Escherichia coli ATCC 29998, Klebsiella pneumoniae NCTC 5046, Pseudomonas aeruginosa ATCC 27853, Salmonella cholerasuis ATCC 14028 and Salmonella enteritidis ATCC 13076). Results of the antibacterial screening revealed that the oil of Cyperus rotundus L was active against Gram-positive bacteria specially Staphylococcus aureus but had no inhibitory activity against Gram-negative bacteria
