Effects on Antibacterial and DNA Protection of Organic Dyestuff Extracts Obtained from Hazelnut Nuthusk

Abstract

Abstract:Hazelnut is of great important in agricultural export of our country. It has an annual export of one and a half billion dollars. Every new product that will increase the value of the nut is very important. In recent years, natural dye materials used especially in textile materials are important and those of plant origin are preferred. For this purpose, we have made a natural dye extracts from hazelnut nuthusk after collected, dried and grinded of samples. Some biological activities have been carried out showing the suitability for industrial use of the dye extracts obtained from hazelnut nuthusk. Within the scope of our study, the effect of extracts obtained from the hazelnut nuthusk of the Düzce region was evaluated on anti-bacterial and DNA protection. From the extracts obtained, antibacterial activity tests were analyzed by disk diffusion method using 3 different standard bacterial strains as S. aureus, E. coli and P. aeruginosa. pBR322 plasmid DNA and UV-C method was used for DNA protective activity. Four different extracts of dyestuff has showed antibacterial activities to S. Aureus and two different of them P. aeruginosa but none of the samples antibacterial properties to E. coli bacterial strains. It has been determined that the all of dyestuffs extracts obtained from the hazelnut nuthusk have potential for protection against the effects of UV-C and H 2 O 2 on DNA.

Purification of Capsaicin and Molecular Biological Activity Evaluation

“…In contrast to antioxidants, oxidant equilibrium may deteriorate in a direction, resulting in many pathological conditions such as cancer, immune system disorders, cardiovascular diseases. Therefore, preserving this balance is extremely important for health (Bayil Oguzkan et al, 2016).In particular, UV-C (~ 260nm.) Is strongly absorbed by DNA and UV-B rays react with DNA and other biological molecules.…”
