Twenty seven essential oils, isolated from plants representing 11 families of Portuguese flora, were screened for their nematicidal activity against the pinewood nematode (PWN), Bursaphelenchus xylophilus. The essential oils were isolated by hydrodistillation and the volatiles by distillation-extraction, and both were analysed by GC and GC-MS. High nematicidal activity was achieved with essenti...
Litsea cubeba L., also named as Makauy, is a traditional herb and has been used as cooking condiment or tea brewing to treat diseases for aborigines. The present study was undertaken to explore the chemical compositions of the fruit essential oil of L. cubeba (LCEO) and the immunomodulatory effect of LCEO on dendritic cells and mice. The LCEO was analyzed using gas chromatography (GC) and gas c...
The essential oils associated with the flowers of Tithonia diversifolia (Hemsl.) A. Gray were extracted and characterized via hydrodistillation and Gas Chromatography. Hydrodistillation was done in an all-glass Clevenger-type apparatus. The extracts from the hydrodistillation were subjected to gas chromatography where the components of the essential oils were separated based on their molecular ...

Clove buds and lemongrass leaves were collected from three different locations of India and the essential oil was separated by hydrodistillation procedure. The essential oils were studied for its variation in physical properties and chemical composition. Chemical analysis by GC-MS evidenced that the main components of clove oil (CLV) were eugenol (78.5-87.7%) and caryophyllene (12.3-20.2%) and ...
Spotted wing drosophila (SWD, Drosophila suzukii (Matsumura), Diptera: Drosophilidae) is recognized as an economically important pest in North America and Europe as well as in Asia. Assessments were made for fumigant and contact toxicities of six Myrtaceae plant essential oils (EOs) and their components to find new alternative types of insecticides active against SWD. Among the EOs tested, Lept...
