Gojiberry (Lycium barbarum L.) Meyvesinin Farklı Çözgenlerden Elde Edilen Ekstratlarının Toplam Fenolik İçerikleri İle Antioksidan ve Antimikrobiyal Aktivitelerinin Karşılaştırılması

Bu çalışmada besleyici ve antioksidan özelliklere sahip bir "süper gıda" olarak kabul edilen Goji berry  (Lycium barbarum L.) asetik asit+su ve etanol ektraktlarının toplam fenolik madde miktarı ile antioksidan ve antimikrobiyel aktiviteleri gibi biyoaktif özellikleri incelenmiştir. Farklı çözücüler kullanılarak hazırlanan ektratlarda en yüksek toplam fenolik madde içeriği 5148 µg GAE/g ile etanolde tespit edilmiştir. Antioksidan aktivite sonuçlarına göre en yüksek DPPH inhibisyonu %68,92 olarak asetik asit+su ektraktında belirlenmiştir. Disk difüzyon yöntemine göre ekstraktların antimikrobiyel özellikleri değerlendirildiğinde test mikroorganizmalarından Staphylococcus aureus ve Listeria monocytogenes’ e karşı güçlü bir antimikrobiyel etkiye sahip oldukları tespit edilmiştir.
