In vitro antimutagenicity of Allium Tuncelianum ethanol extract against induction of chromosome aberration by mutagenic agent Mitomycine C

Allium Tuncelianum, Tunceli/Türkiye’de lokalize olmuş bir sarımsak türüdür. Sarımsak bitkisi organosülfür bileşikler adı verilen, antikarsinojenik ve antimutajenik etkileri olduğu daha önceden bildirilmiş olan biyolojik yönden aktif komponentler içermektedir. Bu çalışmada A. Tuncelianum ethanolik ekstraktının in vitro antigenotoksik aktivitesi, kromozom aberrasyon testi ile insan lenfosit hücre kültüründe çalışılmıştır. A. Tuncelianum ekstraktı etanol ile soxhlet kullanılarak elde edilmiştir. Bu araştırmada A. Tuncelianum’un etanolik ekstraktı insan lenfosit hücrelerinde kromozom aberrasyon testi ile antigenotoksik aktivitesi çalışılmıştır. A. Tuncelianum’un etanolik ekstraktı, 0.10, 0.15, 0.20 ve 0.25 μl/mL konsantrasyonlarda aseton (negative kontrol) ve Mitomisin C (pozitif kontrol)’ye karşı kromatid ve kromozom kırıkları, kromozom değişimi, kromatid birleşimi ve poliploidi bakımından taranmıştır. Uygulamadan 24 saat sonra, kromozomal aberrasyon frekansı bakımından A. Tuncelianum’un etanolik ekstraktı tüm konsantrasyonlarda önemli bir düşüş ortaya koymuştur. Sonuç olarak A. Tuncelianum’un etanolik ekstraktı MMC uygulanan kültür hücreleri ile karşılaştırıldığında kromozomal aberrasyonda önemli bir düşüşe neden olmuştur. Bu sonuçlara gore A. Tuncelianum’un mutajenite ve karsinojeniteye karşı koruyucu gıda olarak diyetle tüketilebileceği düşünülmektedir.

Mutajenik ajan mitomisin C ile uyarılmış kromozom aberrasyona karşı allium tuncelianum etanolik ekstraktının in vitro antimutajenik etkinliği

Allium Tuncelianum is a garlic species which is locally produced in Tunceli, Turkey. Garlic contains several biologically active compounds known as organosulfur compounds which are reported to have anticarcinogenic and antimutagenic effects. Present study examined the in vitro antigenotoxic activity of ethanolic extracts of A. Tuncelianum in human lymphocyte cells by chromosome aberration test. Samples of A. Tuncelianum were extracted by ethanol using soxhlet extractor. The extract was tested on human lymphocyte cell culture in vitro chromosome aberration test. The effect of ethanol extract of A. Tuncelianum at concentrations of 0.10, 0.15, 0.20, 0.25 μl/mL were screened for chromatid and chromosome breaks, chromosome exchange as well as chromatid union and polyploid cells against negative acetone and positive control Mitomycine C. A significant decrease in the frequency of chromosomal aberration was observed for all treatments with A. Tuncelianum ethanol extract at 24 h. In conclusion, ethanol extract of A. tuncelianum significantly reduced the chromosomal aberration rate as compared with the culture treated with MMC. The results could also indicate that A. Tuncelianum could be protective against mutagenic and carcinogenic compounds when consumed through the diet.
