EVALUATION OF MINERALS, PHENOLICS, RADICAL SCAVENGING ACTIVITY, TOTAL OXIDANT STATUS AND TOTAL ANTIOXIDANT STATUS OF NEPETA VISCIDA BOISS.

Abstract

In the present study, mineral and total phenolic content, radical scavenging activity, total oxidant status and total antioxidant status of endemic Nepeta viscida species were investigated. Total phenolic content of Nepeta Viscida methanol and acetone extracts was determined as gallic acid equivalent. In the extracts, these values were determined as 128.86 ± 4.52 and 134.78 ± 9.3 μg GAE / mg extract, respectively. BHT was used as a standard for radical scavenging effect. It was observed that the radical scavenging effect of Nepeta viscida methanol extract was similar to that of the synthetic antioxidant BHT and higher than the effect of acetone extract. TAS, TOS were measured and OSI values were calculated with TAS and TOS findings. Mineral substances included in the species were identified by ICP-OES. Nepeta viscida contained elements (Mn, Zn, Se, Fe, Cu) that were incorporated in the antioxidant enzyme structure. Furthermore, it was considered that total phenolic content found in Nepeta viscida could be used in phytotherapeutic studies, especially in antioxidative effect studies due to their impact against radicals.
