Phytochemical characteristics variation of different populations of Tanacetum parthenium cultivated in Shahrekord climatic

Background and aim: Tanacetum parthenium L. is herbaceous perennial medicinal plant belonging to the Asteraceae family. Feverfew is used as an analgesic, housing, fever-lowering, anti-rheumatism and migraines in traditional medicine. The most important active ingredient of the herb is essential oil. Variation on genetic and environmental conditions play a major role in the growth, development, quality and quantity of active ingredients of medicinal plants, so this study was conducted  to evaluate the diversity of phytochemical characteristics of eight different populations of Tanacetum parthenium at 2014 in Shahrekord region, southwestern Iran. Material and methods: In this study, Tanacetum parthenium seeds were collected from eight regions of Iran. After preparing the seedlings in greenhouses at Research Center in Islamic Azad University of Shahrekord, the plantlets were transferred to the field of University in early April 2014. Aerial part of the plants were harvested at two stages (50% and 100%) of flowering. Hydro-distillated essential oils were analyzed by GC and GC/MS. Results & Discussion: The highest essential oil yield was obtained from the Gilan population at 100% flowering and the lowest essential oil yield was obtained from the Ziarat population at 50% flowering. The results showed that the major compounds were camphor and bornyl acetate and the highest percentage of camphor was identified in the Shahrood population with 49.05% at fifty stage of flowering. Recommended applications / industries: According to essential oil yield and composition (especially comphor and bornyl acetate content) results indicated that two populations of Gilan and Shahrood are suitable to cultivate at Shahrekord climate.
