Analysis of volatile components from Tanacetum cadmeum by hydrodistillation and direct thermal desorption methods using GCxGC-TOF/MS

摘要

The genus Tanacetum with ca. 200 species is widespread mainly in Europe, Asia, and North America [1–3]. The plant is 30–150 cm tall [3, 4] and has a hairy stem and woody roots and branches. It is an aromatic perennial plant. Tanacetum extracts have been widely used against intestinal worms, kidney disease, and respiratory infections [2]. They are also natural antioxidants [5]. Tanacetum species have been used since ancient times. They have traditionally been used as a repellent and deterrent against insects and to alleviate the symptoms of migraine, arthritis, and psoriasis [6]. The dynamic headspace technique is a very popular method for analyzing volatile compounds in food [7] and plant materials [8]. Direct thermal desorption (DTD) is one of the dynamic headspace techniques with cryogenic trapping. This technique allows for the qualitative and/or quantitative analysis of volatile compounds with little or no sample preparation [9]. The main objectives of this study are to characterize the composition of the volatile fractions obtained from the leaves and flowers of Turkish endemic T. cadmeum analyzed by GC×GC-TOF/MS and to carry out a comparative evaluation of its composition with respect to the isolation techniques, namely HD and DTD. Reviewing the literature, it appears that the chemical composition of the essential oil of T. cadmeum has not been investigated before.
