Farklı Yörelere Ait Sumak Ekşilerinin (Rhus coriaria L.) Antimikrobiyal Aktivitesi ve Hipoglisemik Etkisinin Araştırılması

Bu çalışmada, farklı yörelere ait sumak ekşilerinin antimikrobiyal aktivitesi ve antidiyabetik etkisinin belirlenmesi amaçlanmıştır. Rhus coriaria, Rhus cinsinin yurdumuzda yetişen tek türüdür. Türkiye’ de farklı bölgelerde yayılım göstermektedir. Sumak, ekşilik verici olarak kullanılan bir baharattır. Ülkemizin güney illerinde çoğunlukla tüketilir. Çalışmada Ordu Üniversitesi Biyoloji Bölümü Mikrobiyoloji laboratuvarı kültür koleksiyonundan elde edilen üç Gram (-), üç Gram (+) ve bir maya suşu kullanılmıştır. Agar disk difüzyon metodu ile örneklerin antimikrobiyal aktivitesi incelenmiştir. -amilaz ve -glikozidaz inhibisyonunun ölçülmesi ile hipoglisemik etkisi belirlenmiştir. Çalışmamızda hemen hemen tüm örneklerin bakteriler ve mayaya karşı 31,5 ile 6 mm arasında değişen zonlar oluşturduğu gözlenmiştir. Antep örneği Candida albicans ve Hatay örneği Candida albicans ile Staphylococcus aureus’a karşı zon oluşturmamıştır. Sonuç olarak, sumak ekşisinin etkili bir antimikrobiyal aktiviteye sahip olduğunu söyleyebiliriz. Ayrıca sumak ekşisi örneklerini Mersin, Hatay, Gaziantep şeklinde sıralayarak hipoglisemik etkisi olduğunu belirtebiliriz.

The Investigation of Antimicrobial Activities and Hypoglycemic Effect of Sumac (Rhus coriaria L.) Syrups in Different Region

This study aimed to determine the antimicrobial activity and hypoglycemic effect of sumac sours collected fromdifferent regions. Rhus coriaria, is the only species of rhus in Turkey. It shows spread in different regions inTurkey. Particularly, it is used as sour in Anatolia. Sumac sour is usually consumed in south provinces in Turkey.In the study, three Gram (-), three Gram (+) and 1 yeast strains obtained from the culture collection of theMicrobiology Laboratory of Ordu University were used. The antimicrobial effects of samples were investigatedby using agar disc diffusion method. Hypoglycemic effect was investigated with -amylase and -glucosidaseinhibition assays. In result of the study, almost all samples formed zones ranging from 31.5 to 6 mm againstbacteria and yeast, but Antep, Hatay sumac syrup samples did not create against Candida albicans and Candidaalbicans, Staphylococcus aureus, respectively. Consequently, sumac syrups were determined to be an effectiveantimicrobial activity. In addition, we can say that there are hypoglycemic effects of sumac syrup samples inMersin, Hatay and Gaziantep respectively.
