Qualitative and quantitative chemical composition, activity against bacteria, yeasts and moulds and antioxidant activity of two variants (HV400 and HV3200) of hydrolates from dried lavender flowers (Lavandula angustifolia) were determined. The main chemical compounds were linalool (39.2% HV400, 29.0% HV3200), α-terpineol (7.1% HV400, 12.7% HV3200), borneol (4.8% HV400, 9.3% HV3200) and terpinen...
essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. lythrum salicaria has not been previously subjected to examination of its volatile oil. the present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using conventionally hydro-distillation (hd) and microwave a...
Lavender (Lavandula angustifolia) is a shrub of the family Lamiaceae, native to the Mediterranean region. The material used for herbal purposes includes lavender flowers (Lavandula flores) containing essential oil (3%), anthocyanins, phytosterols, sugars, minerals, and tannins. The qualitative and quantitative composition of the essential oil of lavender is variable and depends on genotype, gro...
In this study, different unit operations for distillation, extraction, capturing and separation of essential oil components from plants are evaluated, on the example limonene carvone caraway fruits. Hydrodistillation is standard process obtaining oils leaves distillation water (hydrolate) after phase distilled plant material (pomace) as waste streams. a valorization these streams, using techniq...
This study aimed to investigate the chemical composition of steam distillate essential oil and corresponding hydrolate obtained from S. officinalis grown in Serbia, as well influence weather conditions (temperature precipitations) on their profiles. Furthermore, antimicrobial activity was investigated vitro. The main compounds were cis-thujone, followed by camphor, trans-thujone, 1,8-cineole, w...
The objective of this study was to evaluate the larvicidal activity of essential oil aqueous solutions (hydrolates) obtained by steam distillation of stalks and leaves of Croton argyrophylloides, Croton nepetaefolius, Croton sonderianus and Croton zehntneri against Aedes aegypti larvae. Twenty-five larvae of third instar were placed in plastic beckers, containing the hydrolates (50 mL), in a fo...
