The goal of present study is to find the penolic contents, antioxidant activities and antimicrobial capacities in the seeds of five Salvia L. taxa two of which are endemics (Salvia euphratica var. leiocalycina and Salvia euphratica var. euphratica). The flavonoid and phenolic acid are determined by using HPLC while the antioxidant activities are determined based on different methods. Also, the antimicrobial activities of some Salvia species are determined by using the well agar method. The current study found that the studied Salvia species have low flavonoid. It has been found that Salvia euphratica var. euphratica has high vanillic acid, ferulic acid and rosmarinic acid among the studied taxa. Similarly, it has been found that Salvia euphratica var. euphratica has high DPPH and ABTS radical scavening capacity in all concentrations. It has been also found that Salvia euphratica var. euphratica has highest total phenolic content (372,63±0,87 µgGAE/mg) whilst Salvia tricholoda has low total phenolic content (46,41±1,71 µgGAE/mg). In addition, this study demonstrated that Salvia tricholoda has lowest metal chelating activity (37,35±0,51%). Furthermore, present study found that the lipid peroxidation levels of the studied Salvia taxa are between 18,21±0,37 mg/kg and 21,03±0,22 mg/kg while it has been found that the antibacterial properties of the Salvia taxa under study are altering.

İncele - MakaleAçık Erişim2021Nhibitory Property of Poly (AN-co-VP) Copolymer on Some Dermatophyte Fungiand Yeasts Causing Fungal Infections
Torgut, Gulben; Kirbag, Sevda; Sönmez, Pınar Erecevıt; Pıhtılı, Güzin
Antimicrobial susceptibility test for poly (AN-co-VP) copolymer, which we think could be an ideal drug in treatment interventions was evaluated with disk diffusion method and minimum inhibitor concentration. In the antimicrobial measurement data, it was determined that the poly (AN-co-VP) copolymer dissolved in pure water is a significant inhibitory property against the growth of yeast (on Candida spp. with 11.33±0.3 mm barrier area) and dermatophyte fungi (on Epidermophyton sp. and Trichophyton sp.with 12.33±0.3 mm barrier area) (p<0.001) and no inhibitory properties were observed in preventing the growth of all bacteria (Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Staphylococcus aureus, Bacillus megaterium). MIC limit values that prevent the growth of dermatophytes and yeasts supporting the disc diffusion method are 50-100 μL. This study is an alternative approach in order to limit the spread of superficial fungal infections they cause and eliminate these infections that tend to become chronic since this polymer extract has no inhibitory properties on bacteria but prevents the growth of yeast and dermatophytes.

Kirbag, Sevda; Sönmez, Pınar Erecevıt; Pıhtılı, Güzin
Bu çalışmada insanlarda ciddi hastalıklara neden olan bakteri, maya ve dermatofit mantarları gibi mikroorganizmalar üzerindeki poli dimetilakrilamid-ko-metilmetakrilat’ın poli P (DMAA-co-MMA) diklorometan içeren çözeltilerinin inhibitör etkilerini araştırıldı. Disk difüzyon yöntemi ile incelenen bu çözelti, Bacillus megaterium ve Klebsiella pneumoniae dışındaki tüm bakterilerin (Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus) ve dermatofit mantarlarının çoğalmasını engelleyerek antimikrobiyal özelliğe sahiptir. Antimikrobiyal duyarlılık verilerinde, diklorometan içinde çözünen poli P (DMAA-ko-MMA) maya ve dermatofit mantarlarının büyümesine karşı inhibe edici bir etkiye sahiptir (Candida spp. üzerinde 11.3mm / inhibisyon alanı - 12.3 mm / inhibisyon alanı) ve Epidermophyton sp. üzerinde 11.3 mm / inhibisyon alanı - Trichophyton sp. üzerinde 11.3 mm / inhibisyon alanı) (P <0.001). Disk difüzyon yöntemini güçlendiren MIC (Minimal inhibisyon konsantrasyonu) sınır değerleri bakteriler, mayalar, dermatofitlerin büyümesini engelleyen en küçük değer olarak 50-100 μL'dir (10 mL de 4500- 9000 μg). Antimikrobiyal bileşik, gelecek bu alandaki çalışmaları aydınlatmak için büyük avantaj sağlayabilir. Çalışmada kullanılan polimer, iltihaplanma ve mantar enfeksiyonlarına neden olan mikroorganizmalar ile savaşan antimikrobiyal polimerlere umut verici yeni bir katkı sağlayacaktır.

Although there are many studies on the activities of different species, the compounds and effects of Centaurea L., the largest genus of the Turkish flora, on human health, no relevant studies have been conducted on the antimicrobial properties of the usable parts (above ground leaves, flowers) of C. urvillei DC. subsp urvillei against pathogenic microorganisms.This study aimed to show whether it prevents the growth of these microorganisms that cause infectious diseases in humans on bacteria, yeast, dermatophytes that cause infectious diseases in humans via well agar and microdilution method by applying a methanol solution of the usable parts of C. urvillei DC. subsp. urvillei. Regarding the antimicrobial susceptibility results, the plant solution formed a generally sensitive inhibition zone (14.66 mm-11.66 mm inhibition zone-1 diameter) on inhibition of growth of yeast, dermatophyte isolates and other bacteria. This means that 40 mg dose of C. urvillei DC. subsp. urvillei has antibacterial and antifungal that can prevent the growth of all test microorganisms (Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 29213, Enterococcus faecalis ATCC 29212, Klepsiella pneumoniae clinical isolate, Candida albicans RSKK 02007, Candida glabrata RSKK 014019, Candida tropicalis RSKK 02011, Epidermophyton floccosum RSKK 14024, Trichophyton rubrum RSKK 03022) that cause disease. It is seen when we compared with the control group that there was no significant difference in bacteria, however, a significant difference was observed in yeast and dermatophytes (p

In this study, the antimicrobial effect researched on microorganisms threatening to human health of extract including methanol of Centaurea saligna that is endemic and used for therapy of many diseases. For disk diffusion method, this related extract is highly effective on the gram negative bacteria by its 20.3±0.5 mm inhibition area. Again to relation bacteria, gram positive bacteria are highly effective by 18.3±0.57 mm and 20.3±0.5 mm inhibition area. It has a effect against Candida species and Epidermophyton sp., the superficial skin infections are caused, by 9.6±0.5 mm and 13.6±1.5 mm inhibition area. On the other hand, for findings, this related extract is extremely effective against Trichophyton sp. that is one of dermatophyte fungi by 24.6±1.5 inhibition area. This natural extract shows its antimicrobial effect namely, by minimal inhibition value (MIC): 6.25 µL its lowest inhibition value against development of all the bacteria and dermatophyte fungi. This plant has a potential to be a natural antimicrobial agent to be used as a medicine for human health and life quality.
