Şırnak Bölgesi'ndeki Halk Arasında Tıbbi Amaçlı Kullanılan Bazı Bitkilerin Antioksidan Ve Biyolojik Aktivitelerinin Belirlenmesi

Bu çalışmada, Şırnak ilinin İdil ilçesine bağlı Akkoyunlu köyünde yetişen ve halk arasında tıbbi amaçlı kullanılan; Antep Fıstığı (Pistacia vera L.), Dardağan (Celtis aetnensis), Menengiç (Pistacia terebinthus L.), Alıç (Crataegus monogyna), Sumak (Rhus Coriaria L.), Badem (Prunus dulcis), Acıbadem (Amygdalus Amara), ve Rezene Out (Foeniculum Vulgare) isimli odun dışı orman ürünlerinin meyveleri ve yaprakları incelenmiştir. Bitki ekstraktlarının antioksidan içeriklerini belirlemek için çeşitli yöntemler kullanılmıştır. Bu çalışmada seçilen bitkilerde toplam fenolik ve flavonoid içerikleri incelenmiştir. Antioksidan aktivite tayini için FRAP (Demir İndirgeme Antioksidan Gücü) ve CUPRAC (Bakır İndirgeyici Antioksidan Kapasite) analizleri kullanılmıştır. Aynı zamanda her bir örneğin antimikrobiyal aktivitesi minimum inhibisyon konsantrasyon (MİK) yöntemi ile incelenmiştir.

Determination of Antioxidant and Antimicrobial Activities of Some Medicinal Plants Grown in Şırnak Region of Turkey

In this study, fruits and leaves of non-wood forest products such as leaves and fruits of Pistachio (Pistacia vera L.), Celtis (Celtis aetnensis), Terebinth (Pistacia terebinthus L.), Hawthorn (Crataegus monogyna), Sumac (Rhus Coriaria L.), Almond (Prunus dulcis), Bitter Almond (Amygdalus Amara), and Fennel (Foeniculum Vulgare) which are used for medical purposes in the village of Akkoyunlu in Şırnak were investigated. Several analyzes have been used to determine antioxidant activity of herbal products. Flavonoids and total phenolics ingredients of elected herbs were examined in the present study. CUPRAC (Cupric Reducing Antioxidant Capacity) and FRAP (Ferric Reducing Antioxidant Power) analyzes were utilized for measurement of antioxidant capacity. In addition, antimicrobial capacity was determined by Minimum Inhibitory Concentration (MIC) technique for each sample. According to the antioxidant results determined, among the samples examined fruit of the sumac (Rhus Coriaria L.) plant has the best antioxidant activity in almost all applied antioxidant analyzes. On the other hand, fruit of almond (Prunus dulcis) was found to show low antioxidant activity in almost all analyzes.
