In this study, water-distilled essential oils from the flowers of Tanacetum zahlbruckneri and flowers and stems of Tanacetum tabrisianum from Turkey were analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The flower oil of T. zahlbruckneri was characterised by the sesquiterpenes germacrene D (29.7%) and spathulenol (12%). Flower (A) and stem (B) oil of T. tabr...

Extensive investigations on essential oil composition, antimicrobial, insectici...

Background & Aim: Tanacetum is a member of Asteraceae family and its twelve species such as Tanacetum walteri are endemic to Iran. In this investigation, chemical compounds and antimicrobial activity of essential oils of Tanacetum turcomanicum (Krash.) and Tanacetum walteri (C.Winkl.) were studied. Experimental: The pla...

Laurus nobilis L. (sweet laurel) is one of the volatile oil bearing plants of Lauraceae family. It is cultivated in different parts of Iran and its leaves and fruits have been used in food, cosmetics and pharmaceutical industries. There are a few reports about the effects of some environmental conditions on the quality and quantity of laurel volatiles. The goal of our work was to searc...

A microwave-assisted hydrodistillation protocol was modified to extract essential oils from leaves of Salvia triloba L. and Laurus nobilis L. The essential oils of these plants are generally obtained by hydrodistillation or steam distillation. The volatile compounds obtained by microwave-assisted hydrodistillation and hydrodistillation methods were analyzed by GC and GC/MS. Both distillation me...
