The essential oil was obtained from crushed seeds, extracted through Hydrodistillation method. The percentage yield of Carum roxburghianum was found 4.7% respectively. Physical properties i.e., colour, odour, specific gravity, solubility, refractive index, acid value and ester value were recorded according to the standard procedures. Chemical composition of essential oil of Carum roxburghianum ...

Analysis of seasonal changes in the composition Scots pine oleoresin by 1H and 13C NMR spectroscopy was carried out. Due to favorable weather conditions (positive temperatures on days sampling throughout year) samples for each 12 months were obtained studied. Chloroform (CDCl3) solutions Eight resin acids identified quantified: abietic, dehydroabietic, isopimaric, levopimaric, neoabietic, palus...

The impact of relative humidity (RH) on organic new particle formation (NPF) from ozonolysis monoterpenes remains an area active debate. Previous reports provide contradictory results indicating both depression and enhancement NPF under conditions moderate RH, while others do not indicate a potential impact. Only several have suggested that the effect may depend absolute mixing ratio precursor ...

ferulago angulata subsp. carduchorum (boiss. & hausskn.) d.f. chamb is a perennial species of the family apiaceae and is locally used as a flavouring agent and for some medicinal properties. the essential oil of this plant if found to possess antibacterial and antifungal activities. the present study is aimed to determine constituents of essential oils from inflorescence of four f. angulata sub...

the present study was designed to determine the effects of the essential oil of laurusnobilis l. (lauraceae) and its three main components on α-glucosidase and reactive oxygenspecies scavenging activity. the chemical composition of the essential oil from laurus nobilisl. leaves was analyzed by gc/gc-ms and resulted in the identification of 29 compounds,representing 99.18% of the total oil. 1,8-...

The monoterpene compound has been reported to have antiviral activities . This study aimed test the in Melaleuca leucadendra inhibit SARS-CoV-2 virus. monoterpenes tested were α-Pinene, β-Pinene, Linalool, α-Terpineol, and Terpinene-4-Ol. method used was computational through pharmacophore analysis. indicator for quality of fit score. A score more than 50% indicates a good-quality compound, whi...

This study focused on five different subspecies of Portuguese Daucus carota L., to identify the main compounds in essential oils umbels from each subspecies. The isolation was performed by hydrodistillation methods followed further composition analysis gas chromatography-mass spectrometry, ultimately demonstrating that had major compounds. concluded found subsp. maritimus were geranyl acetate, ...
