“…These results were in agreement with Wang et al (2013) and Khan et al (2012) who found a strong correlation between DPPH and ABTS assay. Likewise, many literatures reported show a strong relationship between the total phenolic content and the free radical scavenging activity of plant extracts (Shabir et al, 2011;Gonçalves et al, 2013;Othman et al, 2007).…”

Background: The genus Asphodeline (Liliaceae) is represented in Turkey by 20 taxa, which are traditionally used for medicinal purposes in Anatolia. Materials and Methods:In this study, we tested the phytochemical content and antioxidant effect of different solvent extracts obtained from different anatomical parts of Asphodeline anatolica. The different extracts of each plant parts were tested for antioxidant activity using different chemical assays. The total antioxidant components were also calculated. Results: Generally, acetone extracts produced the seed and root exhibited significantly higher antioxidant activity with high antioxidant components. Total phenolic content of extracts were significantly correlated with antioxidant potentials (except for, metal chelating activity). Conclusion: On the basis of the results obtained, A. anatolica extracts should be regarded as a valuable source of natural antioxidants for food and therapeutic applications.Key words: Asphodeline, Antioxidant activity, Free radical scavenging, Phenolics, Solvent extracts, Turkey. IntroductionFree radicals, especially reactive oxygen species (ROS), are highly unstable molecules; react with various organic substrates such as lipids, proteins, carbohydrates and DNA. The excessive production of free radicals is called "oxidative stress" and can result in serious diseases including cancer, atherosclerosis, rheumatoid arthritis and neurodegenerative diseases (Arouma, 2010). Defense against oxidative stress is therefore very important in preventing the development of diseases mentioned. Antioxidants are vital substances which possess the ability to protect the body from the damage caused by these radicals (Silva et al., 2005). Hence, it has been suggested that there is an inverse relationship between dietary intake of antioxidants and the incidence of the diseases related to oxidative stress (Rice-Evans et al., 1997;Lu and Foo, 2000). Although synthetic antioxidants such as butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), propyl gallate (PG) are commonly used for food processing, their toxic properties and unwanted side effects limit their widespread use (Lindenschmidt et al., 1986;Kehrer and DiGiovanni, 1990). For this reason, there has been a particular interest in the potential health benefits of natural antioxidants in medicinal and aromatic plants. In fact, many functional phytochemicals such as phenolics, flavonoids and carotenoids possessed powerful antioxidant activities (Wang et al., 2013) The genus Asphodeline belongs to the Liliaceae family and is present in south-west of Asia, Middle-Eastern countries and Mediterranean region. The genus comprises of 14 species worldwide. In Turkey, this genus represented by 20 taxa and 11 of them are endemic to Turkey (Mathews and Tuzlaci, 1984;Tuzlaci, 1987). The high number of endemics shows that Turkey is one of the gene centre of this genus. The Asphodeline species are known as çiriş plants and are abundant especially in the mountains and steppes of inner Anatolia regio...

“…Plant derivatives, such as infusions and decoctions, have since long been used in traditional medicine for prevention and treatment of several pathologies [1,2] . Including common infectious diseases, leading causes of morbidity and mortality [3] , which are directly responsible for 26% of annual deaths worldwide [4] , were also treated by those plants preparations since ancient times [5] .…”

“…Among them, phenolic compounds, owing to their acknowledged antioxidant, anti-inflammatory, antimicrobial and antitumor properties, have the highest potential to prevent, reduce and/or treat several pathological conditions (Espín, García-Conesa, & Tomás-Barberán, 2007;Huang, Boxin, & Prior, 2005;Hübsch, Van Zyl, Cock, & Van Vuuren, 2014). Flavonoids and phenolic acids, in particular, are known for their high biological activity, having been reported for their positive effect in the prevention of a several chronic diseases (Bordoloi et al, 2016;Umar Lule & Xia, 2005), or their capacity as food preservatives by stabilizing lipid peroxidation and inhibiting different enzymes associated to oxidation processes (Bernal, Mendiola, Ibáñez, & Cifuentes, 2011;Gonçalves, Gomes, Costa, & Romano, 2013;Shan, Cai, Sun, & Corke, 2005).…”

How gamma and electron-beam irradiations modulate phenolic profile expression in Melissa officinalis L. and Melittis melissophyllum L.

A B S T R A C TOwing to the overall increase in herbal infusions' consumption, there's a progressively higher need of suitable plant material, as well as adequate conservation techniques to maintain its quality. Among, the available technologies, irradiation is gaining interest as a feasible preservation method. In line with this approach, this wok was designed to evaluate the effects of electron-beam and gamma irradiation over the phenolic profiles of two plant species Melissa officinalis L. (LB) and Melittis melissophyllum L. (BB). Individual phenolics were characterized by high-performance liquid chromatography coupled to a diode array detector and a mass spectrometer (HPLC-DAD-ESI/MS). Irradiated samples showed a general increase in individual phenolic contents, especially in lithospermic acid A in LB and 5-O-caffeoylquinic acid in BB. Thus, this study revealed the potential usefulness of both conservation technologies when employed to this type of plants.
