Twenty-nine anise seed samples were collected from different locations in 9 producer provinces in Turkey and were used as the study materials in order to determine essential oil and essential oil compositions. According to the results, essential oil levels varied from to . The major component of the essential oil was trans-anethole. This compound ranged from to . Population 26 may be recommended for trans-anethole percentage and populations 8 and 22 for essential oil content. Key Words: Anise populations, Pimpinella anisum, essential oil content, essential oil composition, trans-anethole Türk Anason Populasyonlar›n›n Uçucu Ya¤ Miktar› ve Bilefliminin De¤iflimi Özet: Bu araflt›rma, Ankara Üniversitesi, Ziraat Fakültesi, Tarla Bitkileri Bölümü ve G›da Mühendisli¤i Bölümü laboratuvarlar›nda yürütülmüfltür. Farkl› anason üretim yörelerinden toplanan 29 tohum örne¤i araflt›rma materyali olarak kullan›lm›fl ve bunlar›n uçucu ya¤ miktar› ve bileflenleri belirlenmifltir. Araflt›rma sonuçlar›na göre anason populasyonlar›n›n uçucu ya¤ oranlar› % aras›nda de¤iflmifltir. Uçucu ya¤lar›n ana bilefleni olan trans–anetol oran› % – aras›nda de¤iflim göstermifltir. Uçucu ya¤ içeri¤i bak›m›ndan 8 ve 22 numaral› populasyonlar, trans-anetol için 26 nolu populasyon önerilmifltir. Anahtar Sözcükler: Anason .
