Comparison of the Quantity and Quality of the Essential Oils of the Flowers and Leaves of the Two Subspecies of Achillea millefolium L. with the Pharmacy Source Approach

Achillea millefolium L. is one of the most famous medicinal herbs that has been used extensively in ancient medicine for the treatment of diseases in general and wounds and burns in particular. This plant has many subspecies that different compounds of monoterpene and sesquiterpene are found in its essential oil. The purpose of this study was to analyze and compare the yields and essential oil compositions of two subspecies of Achillea millefolium subsp. millefolium and Achillea millefolium subsp. elbursensis with an economical usability approach in the pharmaceutical and medical sciences. For this purpose, two subspecies were collected from two subspecies in flower and leaf mountain range in July and flowering with three replications. Essential oil extraction was performed by Clevenger method and essential oils were identified by mass spectrometry chromatography (GC / MS). The results of analysis of variance showed that there was a significant difference between the two subspecies in flower and leaf essential oil yield at 1% level and the highest yield belonged to Alborz flower. Also, comparison of the essential oils and essential oils of Alborz aquatic leaves showed that the major part of the essential oils of both organs was chamazolene and was always higher in flower (79.3%) than in leaves (69.2%). However, in the Hibernians, the composition of 1 and 8 cineol was 14.4% in flowers and 5.6% in leaves. Thus, Alborz subspecies can be a unique natural economic resource for the pharmaceutical industry in the production of comazolene-containing drugs such as anti-inflammatory drugs and skin diseases and a subspecies of thousands of leaves grown in Alborz Mountains for extraction of 1 and 8 cineols in various medical and pharmaceutical applications.
