In this study, total phenol, antioxidant activity, fatty acid composition and mineral contents of the Terfezia species known as Domalan located in Konya region were edetermined. The majority of the truffles were gathered around BeÅŸağıl Village Sarnıç Locality, BeÅŸağıl Village Çiftlik Plateau Piren TömeÄŸi Locality, Karapınar Çukurkuyu Plateau, Kale Village. Three species of truffles were identified during field works as Terfezia clavery Chatin, Terfezia sp. and Picoa lefebvrei (Pat.) Maire. Terfezia clavery and Terfezia boudieri are referred to as “Domalanâ€, Picoa lefebvrei is known as the Bird Domalan and Terfezia sp. is called White Domalan. Both crude fat (1.22%) and total phenol content (12.319 mg GAE/100ml) of Terfezia clavery were found to be higher than the other truffles. Oleic, linoleic and linolenic acid were identified as the major fatty acids in the samples. Very low levels of heavy metal content were detected in the samples. Lead (Pb) was not found in the samples of Terfezia clavery and Terfezia sp. The highest elements in the samples were potassium (K) and sulfur (S).
