Volatile Compounds of Shade-Dried Tussilago farfara L. Using Purge and Trap Extraction Technique

Abstract

The leaves and flowers of Coltsfoot have long been used for the therapeutic purposes, especially for respiratory ailments. Coltsfoot is also considered as a natural food flavoring due its aroma-rich property. In the present study, aroma compounds of shade-dried leaves and flowers of coltsfoot were isolated by purge and trap method and analyzed by GC and GC-MS. A total of 30 aroma compounds, including notably monoterpenes and sesquiterpenes were determinated. Results showed that the terpenes, such as; linalool (20.79 %), caryophyllene (16.36 %), α-pinene (9.72%), (E)-β-farnesene (9.07), germacrene (7.78%) and camphene (4.48%), were the most abundant compounds among overall aroma profile.

Gölgede Kurutulmuş Öksürük Otunun (Tussilago farfara L.) Uçucu Bileşiklerinin Taşıyıcı ve Tuzak Yöntemiyle Belirlenmesi

Abstract

Öksürük otunun yaprakları ve çiçekleri uzun yıllardır başta öksürük gibi boğaz yolu enfeksiyonları olmak üzere, birçok farklı hastalığa karşı tedavi amaçlı kullanılmaktadır. Ayrıca, aroma maddelerince zengin oluşu, öksürük otunun gıda sektöründe aroma verici olarak değerlendirilmesine olanak sağlamıştır. Bu çalışmada, gölgede kurutulmuş Öksürük otu yaprakları ve çiçeklerinin aroma maddeleri purge and trap yöntemiyle izole edilmiş ve GC-MS cihazıyla analiz edilmiştir. Çalışmada elde edilen verilere göre, Öksürük otunda baskın olarak moterpenler ve sesquiterpenlerin oluşturduğu toplamda 30 aroma bileşiği tespit edilmiştir. Bu bileşikler içerisinde Öksürük otunda linalool (% 20.79), karyofilen (%16.36), α-pinen (%9.72), (E)-β-farnesen (%9.07), germakren (%7.78) ve kamfen (%4.48) olduğu belirlenmiştir.
