Fruits of Citrus aurantifolia were subjected to hydro-distillation using Clevenger type apparatus to obtain volatile oil. Chemical composition of volatile oil was analysed by GC–MS. Twenty-two compounds representing...

The mosquito Aedes aegypti is the vector of the dengue virus, an endemic arbovirus from tropical and subtropical regions of the world. The increasing resistance of mosquitoes to commercial insecticides impairs regular control programs; therefore, chemical prospecting originating from the Amazonian flora is promising for potential new insecticides. Several Piper species are, notably, rich in phe...

Candida albicans is an opportunistic yeast and a member of the normal human flora that commonly causes infections in patients with any type of deficiency of the immune system. The essential oils have been tested for antimycotic activity and pose much potential as antifungal agents. This work investigated the activity of the essential oil of Cymbopogon winterianus against C. albicans by MIC, MFC...

The essential oil from the leaves of Myrcia ovata Cambess., commonly used in Brazil for the treatment of gastric illnesses, was screened for antimicrobial activity and action in the formation of microbial biofilms by Enterococcus faecalis. The oil was obtained by hydrodistillation using a clevenger-type system. Its chemical composition was analyzed using GC and GC-MS. Both MIC and MBC of the es...

Essential oils from 23 species of plants comprising 14 genera and 4 plant families were obtained by Clevenger-type water distillation. The major compounds in these essential oils were identified with GC-MS and their insecticidal activity against adult turnip aphids, Lipaphis pseudobrassicae (Davis), tested with dosage-mortality bioassays. We examined mortality only for viviparous adults because...

INTRODUCTION Dorema glabrum is an endangered species that grow in Transcaucasia and North West of Iran. The plant has extensive uses e.g. as an herbal remedy or food additive in these regions. The chemical composition of hydrodistilled oil of D. glabrum growing in Iran was analyzed by GC-MS for the first time. METHODS The essential oil of air-dried roots was obtained by hydrodistillation usin...

A large number of plant essential oils have been used against diverse insect pests since they, unlike conventional pesticides, present no risk to humans and the environment. This study was conducted to determine the toxicity of Azilia eryngioides (Pau) Hedge et Lamond (Apiaceae) essential oil against 1to 7-d-old Sitophilus granarius (L.) (Curculionidae) and Tribolium castaneum (Herbst) (Tenebri...

Many essential oils (EOs) of different plant species possess interesting antimicrobial effects on buccal bacteria and antioxidant properties. Eugenia klotzschiana Berg (pêra-do-cerrado, in Portuguese) is a species of Myrtaceae with restricted distribution in the Cerrado. The essential oils were extracted through the hydrodistillation technique using a modified Clevenger apparatus (2 hours) and ...

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 present study reports physicochemical characterization and antioxidant activity of essential oils extracted from guggul (Commiphora wightii) exudates collected from different places in Madhya Pradesh, India. The guggul exudates were hydrodistilled for 3-4 h in Clevenger apparatus. The oil obtained was dried over anhydrous Na2SO4 and stored at 4° until testing. Before extraction of oils from...
