Abstract

S ubcritical water extraction, which is used to extract phytochemicals from different plants and foods, is also called green technology. Orange peel, which a rich source of antioxidant compounds such as phenolics, β-carotene and essential oils, is a valuable by-product in the food industry. In this study, the determination of the relationship between antioxidant activitiy and phenolic compounds of subcritical water extracts obtained from orange peel was aimed. For this aim, The Ferric Reducing Antioxidant Assay (FRAP ), The Cupric Reducing Antioxidant Capacity ( CUPRAC) and DPPH radical scavenging activity ( IC 50 ) of subcritical water extracts were measured. T otal phenolic content of the subcritical water extracts from orange peel was determined statistically significant (p<0.01) correlated as R 2 =0.98 and 0.92 with FRAP and CUPRAC values. Also, total flavonoid content of the subcritical water extracts from orange peel had very high significant ( P <0.01) positive correlations as R 2 =0.97 and 0.93 with FRAP and CUPRAC values. However, total phenolic and total flavonoid content in the subcritical water extracts from orange peel were statistically significant (p<0.01) correlated as R 2 =-0.68 and -0.70 with IC 50 , respectively.

Özet

Farklı bitkilerden ve gıdalardan fitokimyasal bileşikleri ekstrakte etmek amacıyla kullanılan kritik altı su ekstraksiyonu aynı zamanda yeşil teknoloji olarak da adlandırılmaktadır. Fenolik bileşikler, β-karoten ve esansiyel yağlar gibi antioksidan bileşikler açısından zengin bir kaynak olan portakal kabuğu gıda endüstrisinde değerli bir yan üründür. Bu çalışmada, portakal kabuğundan elde edilen kritik altı su ekstraktlarında antioksidan aktivite değerleri ile fenolik bileşikler arasındaki ilişkinin saptanması amaçlanmıştır. Bu amaçla, kritik altı su ekstraktlarının Demir indirgeme Gücü Aktivitesi ( FRAP), Bakır indirgeme Gücü Aktivitesi ( CUPRAC) ve DPPH radikal süpürme aktivitesi ( IC 50 ) ölçülmüştür. Portakal kabuğundan elde edilen kritik altı su ekstraktların toplam fenolik madde içeriği ile FRAP ve CUPRAC değerleri arasındaki ilişki istatistiksel ( P <0.01) açıdan önemli olup sırası ile R 2 =0.98 ve 0.92 düzeylerinde bulunmuştur. Aynı zamanda, portakal kabuğundan elde edilen kritik altı su ekstraktların toplam flavonoid içeriği de FRAP ve CUPRAC değerleri ile istatistiksel ( P <0.01) açıdan önemli düzeyde ilişkilidir (sırası ile R 2 =0.97 ve 0.93). Buna karşın, portakal kabuğundan elde edilen kritik altı su ekstraktların toplam fenolik madde ve toplam flavonoid içerikleri ile IC 50 değeri arasındaki ilişki sırası ile R 2 =-0.68 ve -0.70 düzeylerinde olup istatistiksel ( P <0.01) açıdan önemlidir.
