Valeriana dioscoridis Sm. Ekstraktlarının Biyoaktivite ve Fitokimyasal Kompozisyon Değişimleri

Kedi otu (Valeriana dioscoridis Sm.) Caprifoliaceae familyasının çok yıllık bitkisidir. Bu çalışmanın amacı tüketimi gittikçe artan bitkilerden olan V. dioscoridis bitkisinin besin değerleri, ekstrakt içerikleri, antioksidan ve antimikrobiyal aktivite değerleri gibi kalite kriterleri yönünden, farklı bölgelerde yetişen bitkilerin toplandığı bölgelere gore her hangi bir farklılık oluşturup oluşturmadığının belirlenmesi içindir. Bu çalışmada Valeriana dioscoridis Sm. kök ve rizomları Antalya ilinin sekiz farklı bölgesinden toplanmıştır. Elde edilen materyaller toz haline getirilmiş ve % 80 etanol ile ekstrakte edilmiştir. Toz halindeki bitki örneklerinin makro ve mikro besin elemet içerikleri değerlendirilmiş ve ekstraktların da antioksidan ve antimikrobiyal aktiviteleri değerlendirilmiştir. Elde edilen verilere gore farklı bölgelerde yetişen Valeriana dioscoridis Sm. bitki ekstratlarının antioksidan, antimikrobiyal aktiviteleri ve besin içerikleri ve kimyasal kompozisyonunda farklı değerler elde edilmiştir.

Variation of Bioactivities and Phytochemical Compositions of Valeriana dioscoridis Sm. Extracts

Valerian (Valeriana dioscoridis Sm.) is a perennial herb of the Caprifoliaceae family. The aim of this study was to determine the variation of V. dioscoridis plants grown in different regions in respect of the quality criteria traits such as nutrient values, extract contents and in vitro antioxidant and antimicrobial activity values. In this study, roots and rhizomes of V. dioscoridis Sm. were collected from eight different locations in Antalya province. The obtained materials were ground in a blender and extracted with 80% ethanol. The macro and micro-nutrient elements contents of the powdered plant samples were evaluated and the antioxidant and antimicrobial activities of the extracts were investigated. Based on the data obtained, there were different values in the antioxidant, antimicrobial activities, nutrient content and chemical composition content of extracts of V.dioscoridis Sm. plants grown in different locations.
