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