Nasturtium Officinale Ekstraktlarının Antioksidan Aktiviteleri ve Mineral İçeriğinin Araştırılması

Antioksidanlar, serbest radikallerin zararlı etkilerini yok ederek birçok hastalığı önler. Bu çalışmada, farklı yöntemlerle hazırlanan Nasturtium officinale ekstraktlarının antioksidan kapasitesinin belirlenmesinin yanı sıra Ca, Mg, Zn, Fe, K mineralleri içeriğinin belirlenmesi amaçlanmıştır. Nasturtium officinale'nin metanol ve su ekstraktlarının antioksidan aktiviteleri DPPH, ABTS, DMPD, CUPRAC, FRAP ve Fe3+ Fe2+ indirgeme deneyleri gibi farklı in vitro yöntemlerle belirlendi. Sonuçlar, standart antioksidanlar (BHA, BHT ve Trolox) ile karşılaştırıldı. Hem su hem de metanol ekstraktları, ABTS serbest radikal süpürme tahlilinde yüksek antioksidan potansiyel gösterdi. DMPD deneyinde su ekstraktı daha iyi antioksidan özellik gösterirken, metanol ekstraktı diğer yöntemlerde su ekstraktından daha yüksek antioksidan özellik göstermiştir. Ayrıca Nasturtium officinale’nin klorofil, karotenoid, toplam fenolik ve toplam flavonoid analizlerinin yanı sıra ICP-MS cihazında bitkinin faydalı mineralleri de ortaya çıkarılmıştır. Nasturtium officinale'nin iyi bir mineral kaynağı olan önemli bir bitki olduğunu tespit ettik.

The Investigation on Antioxidant Activities of Nasturtium Officinale Extracts and Its Mineral Content

Antioxidants prevent many diseases by eliminating the harmful effects of free radicals. In this study, it was aimed to determine the antioxidant capacity of Nasturtium officinale extracts prepared by different methods, as well as to determine the Ca, Mg, Zn, Fe, K minerals. Antioxidant activities of methanol and water extracts of Nasturtium officinale were determined by different in vitro methods such as DPPH, ABTS, DMPD, CUPRAC, FRAP, and Fe3+ Fe2+ reduction assays. The results were compared with the standard antioxidants (BHA, BHT, and Trolox). Both water and methanol extracts presented high antioxidant potential on ABTS free radical scavenging assay. While water extract showed better antioxidant properties in the DMPD experiment, methanol extract showed higher antioxidant properties than water extract in other methods. In addition to the chlorophyll, carotenoid, total phenolic, and total flavonoid analyzes of Nasturtium officinale, beneficial minerals of the plant were also revealed in ICP-MS. We determined that Nasturtium officinale is an important herb with a good source of minerals.
