(C,D,E), and subsp. alanyense & Ocak (F) were analyzed using GC/MS. Menthyl acetate (), menthol (), and pulegone () were the main constituents in samples A and B; menthone (), pulegone (), and menthyl acetate () were detected in sample C; isomenthyl acetate (), isomenthone (), and menthyl acetate () were detected in sample D; menthyl acetate (), menthol (), and menthone () were detected in sample E; and hexadecanoic acid (), menthyl acetate (), and hexahydro farnesyl acetone () were the main constituents in sample F. Key words: Calamintha pamphylica subsp. pamphylica, Calamintha pamphylica subsp. davisii, Calamintha pamphylica subsp. alanyense, essential oil composition Calamintha pamphylica alt türlerinin uçucu yağ bileşimleri Özet: Calamintha pamphylica Boiss. & Heldr. subsp. pamphylica (A, B); subsp. davisii (Quezel & Contandr.) (C, D, E) ve subsp. alanyense & A. Ocak (F)’nin toprak üstü kısımlarından, su distilasyonu ile elde edilen uçucu yağların GC/MS analizleri yapıldı. A ve B kodlu yağların analizinde; mentil asetat (% 26,2-40,7), mentol (% 13,5-18,7), pulegon (% 7,7-13,0) ana bileşik olarak bulundu. C kodlu yağda menton % 21,7, pulegon % 19,7, mentil asetat % 9,8; D kodlu yağda izomentil asetat % 16,7, izomenton % 13,4, mentil asetat % 13,0; E kodlu
