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...

Pressurized hot water extraction (PHWE) and hydrodistillation were compared for the extraction of essential oil from Lavandin. Using GC-FID analysis in conjunction with central composite design, the maximum extraction yield was obtained for temperature of 148 o C, pressure of 33.7 (bar), static time of 10.7 (min), dynamic time of 17.6 (min), and flow rate of 0.69 (mL/min). The PHWE is a practic...

According to the World Health Organization, neuropsychiatric disorders pose an increasingly greater burden on health, society, and economy of countries. Currently, there are strategies prevent some these disorders, treatments or means alleviate their symptoms. In case depression, medication consists antidepressant drugs. Such drugs can also be used in other conditions like anxiety, pain, insomn...

The conversion of geranyl pyrophosphate to (-)-endo-fenchol is considered to proceed by the initial isomerization of the substrate to (-)-(3R)-linalyl pyrophosphate and the subsequent cyclization of this bound intermediate. To test this stereochemical scheme, phosphatase-free preparations of (-)-endo-fenchol cyclase from fennel (Foeniculum vulgare M.) fruit were repeatedly incubated with a samp...

In the present study, the percutaneous absorption of the essential oil of lavender from a massage oil was investigated. It was shown that lavender oil penetrates the skin of a male subject. Within five minutes of finishing, the massage traces of linalool (1) and linalyl acetate (2) as the main constituents of lavender oil could be detected in the blood. After 20 minutes, 100 ng/ml for 2 and 121...

Essential oils obtained from inflorescences of three Origanum vulgare L.ssp. hirtum (Link) Ietswaart samples, growing wild in different locations in Campania (Southern Italy), were analysed. Three chemotypes were found: the first, with a prevalence of carvacrol/thymol; the second, characterized by the prevalence of thymol/alpha-terpineol; the third, featuring a prevalence of linalyl acetate and...

GC-MS/FID analysis of the essential oils 10 Thymus species, belonging to Sect. Serpyllum, led identification 118 compounds accounting for 97.79–99.69% total oil. moesiacus, T. jankae, vandasii, longicaulis and sibthorpii were characterized by presence linalool (19.37–35.21%) as major or dominant component, but differed significantly in content other prominent components: linalyl acetate, gerani...

The study was conducted in the wooden canopy of Department Horticulture and Landscape Engineering / College Agriculture Tikrit University during growing season 2021-2022, to effect spraying with glutamic acid nano-zinc oxide on some vegetative growth characteristics, mineral content, active substance anatomical characteristics Lavendula Angustifolia Mill. A factorial trial carried out two facto...

Bergamot (Citrus bergamia, Risso et Poiteau) essential oil (BEO) is a well characterized, widely used plant extract. BEO exerts anxiolytic, analgesic and neuroprotective activities in rodents through mechanisms that are only partly known and need to be further investigated. To gain more insight into the biological effects of this essential oil, we tested the ability of BEO (0.005-0.03%) to modu...
