Sunflower Helianthus) annuus) is oneofthemostimportantoilplantsoftoday. Sunflower oil occupies the first place among the preferred vegetable oils in terms of cooking quality. Sunflower is a hoe plant. It leaves clean and an aired soil to the plant that is cultivated after itself. The cultivation time for sunflower is spring. It should be cultivated in the months of MarchFAprilrightafterthecultivationofgrainand sugar beet in spring when the soil temperature became8f9 C.Cultivationmustbecompletedin Marmara and Thrace regions by April 15.

Materials*and*Methods* Inthisstudy,TuncaMR5580)speciesbelonging to Sunflower Helianthus) annuus) plant widelyf grown in Hayrabolu District of Tekirdag were collected. Antioxidant activity was looked at the seedy part of sunflower collected during physiological and harvesting period. Then, extraction and evaporation processes of sunflower with soxhlet apparatus and rotary evaporator were carried out in the laboratory. AntiFoxidative properties of sunflower seed oil s active materials were determined by using T80+UVFVIS Spectrophotometers. Determination of ph, Lime amount, Organic matter amount, available phosphorus, exchangeable Potassium, Calcium and Magnesium in the soil samples of research area were determined according to Sağlam 2008). Texture in soil samples was determined according to Demiralay, 2003) and someavailablemicroelementsinthesoilsuchas Fe, Cu, Zn and Mn with DTPA method was determinedaccordingtokacar,2009)inicpfoes. βmcarotene*linoleic*acid*method* Total antifoxidant activity of the extracts was determined by βfcaroteneflinoleic acid method whichisbasedonthemeasurementofinhibition of conjugated diene hydroperoxides resulting from linoleic acid oxidation Dapkevicius et al., 1998). βfcarotene solution was prepared by solving2mgofβfcarotenein10mlofchloroform. 25µllinoleicacidand30µlTween20wereadded to 1 ml of this solution. Chloroform was mixed with 100 ml of distilled water after being vaporized in rotary evaporator. 3ml of this emulsion and 250 µl extract solution containing sample were added to the available test tubes.

Soilplaysacrucialroleintheantioxidantcapacity of the plant of such an important plant. Soil sample in the research area had basic property and its saltless, lowflime, loamyftexture, low organic matter content, sufficient available phosphorous content, exchangeable potassium, calcium and magnesium contents as well as its available iron, copper, zinc and manganese contentswereatsufficientleveltable1). Nitrogen,oneofthemacronutritionelements,is one of the important elements that affect productivity as the basic building block and necessary for the synthesis of proteins in plant cells. Nitrogenous fertilizer decreases the oil proportion of the seed as well as increases the protein proportion. It was found that increased doseofnitrogenreducestheoilrateoftheseed. It is the most needed within the nutrients taken from the soil by high plants. 22

9 As a result of activity operations, various mechanisms of antioxidants, such as stopping radical chain reaction, binding transition metal ions, separating peroxides, reduction power and radical removal, depend on reaction conditions such as ph, temperature and solvent Diplock, 1997). Antioxidant activity, at the same time, dependsonthepolarityofextractionsolventand type,isolationtechniquesandthepurityofactive compoundsmeiretal.,1995).whileantioxidant activity of a compound was determined, it was observed that compound had a powerful antioxidantinonemethod,andwasaprofoxidant in another Von Gadow et al., 1997).

At the same time, phenol compounds candirectlycontributetotheantioxidantactivity Duhetal.,1999). Conclusion* Total antioxidant activities, their absorbance values against time and % percentage of antioxidant activity values of extract oils and standard antioxidants of Tunca MR 5580) belonging to sunflower Helianthus) annuus) during physiologic and harvesting period determinedbyβfcaroteneflinoleicacidsystemare provided in Figure 1 and Figure 2. βfcarotene degradation rate and total antioxidant activity results of sunflower extracts and synthetic antioxidants analyzed by the application of βf carotene linoleic acid model system are given in Figure1and2respectively. When we look at the values of degradation rate given in Figure 3.1, we see that the decrease in the values of degradation rate thence in absorbance values of the sample slowly takes place when incubation time increases. The realization of this decrease in speed values, as expressedineryiğit2006),amin2002),makasci Afacanetal.2010),Nagaietal.,2003),Gülçinet al., 2004) and many other studies conducted in literature related to this topic, can be caused by the presence of compounds amino acids, phenolicacids,flavanoids,pyrocatechol,catechin, etc.)withantioxidanteffectandphenolstructure foundintheextracts.
