Doğal bir antimikrobiyel: Oleuropein

Zeytin ağacının temel fenolik bileşiği olan oleuropein, zeytin meyvelerinin karakteristik acı tadından sorumludur. Zeytinin yenilebilir özellik kazanması için mutlaka ortamdan uzaklaştırılması gerekir. Elenolik asit ve hidroksitriosolün heterozidik esteri olan oleuropein, insan sağlığı üzerinde birçok yararlı etkiye sahiptir. Birçok araştırmacı tarafından antimikrobiyel özelliğe sahip olduğu ispat edilmiş olan bu bileşik alternatif gıda katkısı olarak da kullanılabilir. Bu derlemede, oleuropeinin kimyasal yapısı ve antimikrobiyel etkisine ilişkin yapılan çalışmalardan söz edilmektedir.

A natural antimicrobial: Oleuropein

Oleuropein is the main phenolic compound of olive tree and is responsible for the characteristic bitterness of olive fruits. Olive fruits can only be consumed after brining which removes bitterness by leaching out oleuropein and other polyphenols. Oleuropein is a heterosidic ester of elenolic acid and hydroxytyrosol and possesses beneficial effects on human health. Many researchers have demonstrated this compound has antimicrobial property, so that it might be used as an alternative food additive. In this review, the studies about chemical structure and antimicrobial activity of oleuropein are mentioned.
