tailieunhanh - Drug yield and essential oil of Thymus vulgaris L. as in influenced by ecological and ontogenetical variation

Drug yield and volatile oil content and its components of Thymus vulgaris were investigated during the different growing periods under both lowland and mountainous conditions. The highest drug yields were obtained from lowland conditions during the post flowering stage. | Tr. J. of Agriculture and Forestry 22 (1998) 537-542 © TÜBİTAK Drug Yield and Essential Oil of Thymus vulgaris L. as in Influenced by Ecological and Ontogenetical Variation* Menşure ÖZGÜVEN, Sezen TANSI Çukurova University, Faculty of Agriculture, Department of Field Crops Adana-TURKEY Received: Abstract: Drug yield and volatile oil content and its components of Thymus vulgaris were investigated during the different growing periods under both lowland and mountainous conditions. The highest drug yields were obtained from lowland conditions during the post flowering stage. Also, it has been determined that environmental conditions have significantly influenced the harvest dates. The 17 components were identified in the essential oil of Thyme. Essential oil content and its components were significantly affected by both climatic and ecological conditions and various harvest dates. Ekolojik ve Ontogenetik Varyabilitenin Esas Kekiğin Drog Verimi ve Uçucu Yağ Oranına Etkisi Özet: Esas kekiğin kuru herba verimleri ile uçucu yağ oranı ve bileşenleri farklı gelişme devrelerine göre ova ve yayla koşullarında incelenmiştir. En yüksek kuru herba verimleri çiçeklenme sonrasında ve ova koşullarında saptanmıştır. Ayrıca çevre koşullarının hasat tarihlerini önemli derecede etkilediği gözlenmiştir. Esas kekiğin uçucu yağında 17 bileşen saptanmıştır. Uçucu yağ ve bileşenleri iklim ve ekolojik koşullar ile farklı hasat zamanlarından etkilenmiştir. Introduction Thyme (Thymus vulgaris L.) is a perennial Labiatae of the Mediterranean region, which has been used for centuries as spice, home remedy, drug, perfume and insectiside. In Medicine, it is used as antispasmolytic, antibacterial, antifungal, secrotolytic, expectorant, antiseptic, anthelmintic and antitusive as reported by other authors (1-4). More than fifty plants are named and used as “thyme” in Turkey. Most of them belong to the genus Thymus, but some of them to other genera of Lamiaceae such as Origanum, .
