The present study investigates diversity of headspace needle volatiles in native population of Abies x borisii-regis (King Boris fir) from the central Rhodopes (southern Bulgaria) as well as the relationships among this and seventeen previously studied fi... see more

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 hydrodistilla... see more

Plant volatiles can act as chemical signals that influence the behavior and distribution of insects. Although considerable information has been acquired on the effects of plant volatiles emitted from plants on herbivorous insects and their natural enemies... see more

For the first time, chemical composition of P. longifolium essential oils (EO) and head space (HS) volatiles obtained from the fresh leaves, harvested in different phases of the plant development, and inflorescences was compared. The major contributor of ... see more

Ce travaux presente la modalite dans l’a quelle les anesthesiques volatiles, l’halotan et l’isofluran, l’utilises pour l’entretien de l’anesthesie generale qui a ete obtenue grace au technique de narco-neuroleptanalgesie, peut influencee les functions res... see more

Volatile compounds from rosemary dried leaves samples were determined using in-tube extraction technique coupled with GC-MS analysis (ITEX/GC-MS). In order to achieve the best results, the extraction parameters (incubation time, incubation temperature, sa... see more

Volatile components in magma strongly influence many physical properties of melts and minerals. The temperatureresolved degassing analysis of volcanic crystalline and vitreous rocks gives detailed information about volatile compoundsin the melt. Aspecial ... see more

Paper description:The headspace method (HS) enables us to study the composition of volatile compounds by using only 0.1 g of plant material and without creating artefacts during isolation.Volatiles stored in twigs are separated from needle volatiles and t... see more

Fast determination of the volatile com­ponents of widely used culi­nary herbs and spices, without prior preparation of the sample, using headspace sampling (HS) and GC–MS/FID analysis, is presented. Generally, monoter­penes were the dominant class in HS v... see more
