SHORT COMMUNICATION

Antioxidant activity of some Turkish medicinal plants

A. Karadeniza*, I˙. C¸inbilgelb, S.S¸. Gu¨nc and A. C¸etind aDepartment of Biology, Faculty of Science and Art, Mehmet Akif Ersoy University, Burdur, Turkey; bAkdeniz University, Akseki Vocational School, Hunting and Wildlife Programme, Antalya, Turkey; cMinistry of Forest and Water Affairs, VI. Regional Offices, Antalya Branch Manager, Antalya, Turkey; dTurkish Institute for Gifted and Talented, Antalya Branch, Antalya, Turkey (Received 16 September 2014; final version received 6 January 2015)

DPPH, superoxide and nitric oxide radical scavenging activities and total phenolic content (TPC) of some less known plants, distributed in Burdur-Antalya provinces and consumed both as food and for the medicine, Asplenium ceterach L. (golden herb),

Valeriana dioscoridis Sm. (valerian), Doronicum orientale Hoffm. (tiger herb), Cota pestalozzae (Boiss.) Boiss. (camomile), Eremurus spectabilis M. Bieb. (foxtail lily),

Asphodeline lutea (L.) Rchb. (asphodel) and Smyrnium connatum Boiss. and Kotschy (hemlock) were investigated. As a result, the highest 2,2-diphenyl-1-picril hydrazyl (DPPH) radical scavenging activity was determined in C. pestalozzae extract (IC50 ¼ 18.66mgmL21), the highest superoxide and nitric oxide radical scavenging activity was determined in A. ceterach extract (IC50 ¼ 145.17 and 372.03mgmL21).

The highest TPC was determined in A. ceterach extract (59,26mgmL21) as gallic acid equivalent. Further bioactivity and phytochemistry studies on these plants may enlighten new drug discovery researches.

Keywords: Turkish medicinal plants; radical scavenging activity; total phenolic content 1. Introduction

Free radicals and other reactive oxygen species which oxidise important cellular components constantly occurred in biological systems. Antioxidants can eliminate those free radicals and prevent oxidation of important cellular components. Antioxidants which using as additives of diets are very important because some factors, i.e. malnutritional habits, smoke, stress can accelerate or increase generation of free radicals. One of the most important natural sources of antioxidants is the medicinal plants on which many studies conducted so far (Bursal et al. 2013). q 2015 Taylor & Francis *Corresponding author.

The usage of traditional medicines are widespread and plants still present a large source of novel active biological compounds with different activities including antioxidant, antiinflammatory, anticancer, antimicrobial and cardioprotective effects (Cespedes et al. 2008).

Asplenium ceterach L. (golden herb), V. dioscoridis Sm. (valerian), Doronicum orientale

Hoffm. (tiger herb), Cota pestalozzae (Boiss.) Boiss. (camomile), Eremurus spectabilisM. Bieb. (foxtail lily), Asphodeline lutea (L.) Rchb. (asphodel) and Smyrnium connatum Boiss. and

Kotschy (hemLock) are the plants which used as an ethnomedicine in Turkey but their importance could not been understood because they were not known enough. This study was done to investigate DPPH, superoxide and nitric oxide radical scavenging activities and total phenolic content (TPC) of these species. 2. Results and discussion
