SUMMARY
Chemical properties of Crataegus pentagyna subsp. pentagyna, C. orientalis subsp. orientalis, C. orientalis subsp. szovitsii, C. tanacetifolia, C. azarolus var. aronia, C. monogyna var. lasiocarpa, C. monogyna var. monogyna taxa that are naturally distributed in Western Anatolia were determined in this study. Leaf and flower samples collected from Izmit, Sakarya, Balıkesir, Izmir, Kütahya, Muğla and Isparta provinces of Western Anatolia to determine volatile components in 2010-2014 period were dried at room temperature. Volatile components that were obtained by dry phase microextraction (SPME) method in Süleyman Demirel University Central Laboratories were determined in Gas chromatography–mass spectrometry (GC-MS). A total of 81 volatile components belonging to 7 hawthorn taxa were determined. Volatile oil components that were identified at highest ratios were benzaldehyde (82.54%) butyraldehyde (38.27%) and (E)2-hexenal (21.67%) components.
Moisture values of hawthorn seeds samples that were collected from sample areas during ripening period were determined. Fatty acid composition was determined in with Gas Chromatography-Flame Ionization Detector (GC-FID) using standard fatty acid mixture. Moisture values of hawthorn seeds varied between 14.49%-36.33%. 10 fatty acid compositions belonging to 7 hawthorn taxa were determined, the highest were linoleic (64.23%), oleic (39.36%) and palmitic acid (8.16%) respectively.
Key words: Crataegus, volatile component, benzaldehyde, linoleic acid, Western Anatolia, Turkey
INTRODUCTION
UVOD
Turkey has a very rich flora with approximately 11.000 registered plant species (Davis et al., 1988; Güner et al.; 2000, Erik and Tarıkahya, 2004). Flora of Turkey is intriguing not only due to high number of species but also due to high number of endemic species (Ekim et al., 1989).
