The genus Tanacetum L. belongs to the Asteraceae family and Anthemideae tribe is one of the most important medicinal plants that contains 26 species in Iran, 12 of them are endemic. This paper reports the essential oil composition of Tanacetum uniflorum (Fisch. & C.A. Mey. ex DC.) Sch.Bip. growing spontaneously in Salmas (North-West of Iran). Essentail oil extracted by water distillation and st...

The essential oils obtained by hydrodistillation from the stem, leaf and flower of Phlomis aucheri Boiss., which is endemic to Iran, stem, leaf and root of Teucrium polium L. and solvent free microwave extraction oil from leaf of Ajuga chamaecistus Ging. subsp. chamaecistus were analyzed by GC and GC/MS. Germacrene D (11.1%, 28.3% and 21.1%) was the main constituent in the stem, leaf and flower...

Introduction & Aim: Plant growth regulators (PGR) have same effect as natural plant's hormones and can change the main components in plant samples. Chaerophyllum aureum L. is related to Apiaceae family. Experimental: In this paper the qualitative and quantitative composition of the volatile oils of ‎Chaerophyllum aureum L. were reported after using different...
