Chemical composition of the essential oil from Thymus carmanicus Jalas, and its fumigant activity was investigated against two stored product insects, Callosobruchus maculatus (F.) and Sitophilus granarius (L.). Essential oil was isolated via hydrodistillation from dry leaves of T. carmanicus using a modified Clevenger-type apparatus and the chemical composition of the oil was assessed via GC a...

The essential oil of Lippia alba is reported as an antifungal against human pathogenic microorganisms but few articles report its use as an alternative to synthetic fungicides on green mould control. The objective of this study was to determine chemical characteristics of L. alba essential oil and its antifungal activity against green molds as an alternative to synthetic fungicides. Essential o...

The chemical composition of the essential oil of the flowering aerial parts of Monarda didyma L. cultivated in central Italy was analyzed by Gas Chromatography/Mass Spectrometry (GC/MS). The major compounds of the oil were thymol (59.3%), p-cymene (10.3%), terpinolene (9.2%), δ-3-carene (4.4%), myrcene (3.7%), and camphene (3.4%). The essential oil was tested in vitro for its anti-germination a...
