Background: In the recent decade, artificial drying has been one of the most important needs of the pharmaceutical industries. In addition, different drying methods have different effects on the quantity and quality of the essential oils produced from medicinal plants. Objective: The main objective of this study was to evaluate the effects of different drying methods (shade and oven drying a...

studies have shown that oxygenated compounds and tss/ta are important for beverage and food industries. it seems that citrus rootstocks have a profound influence on oxygenated compounds and tss/ta. the aim of this research is to identify rootstock that can synthesize the maximum level of oxygenated compounds and tss/ta. peel oil was extracted using mechanical presses and eluted using n-hexane. ...

The search for more effective and lower cost therapeutic approaches for wound healing remains a challenge for modern medicine. In the search for new therapeutic options, plants and their metabolites are a great source of novel biomolecules. Among their constituents, the monoterpenes represent 90% of essential oils, and have a variety of structures with several activities such as antimicrobial, ...

Monoterpenes are the most essential reactive biogenic volatile organic compounds. Their removal from atmosphere leads to formation of oxygenated compounds, such as nopinone (C9H14O), one important first-generation β-pinene oxidation products that play a pivotal role in environmental and biological applications. In this study, experimental theoretical rate coefficients were determined for gas-ph...

Ocimum basilicum is a valuable source of bioactive metabolites with high preventive and therapeutic effectiveness. Here we aimed to investigate the effect phenological stages (vegetative flowering stages) on essential oil composition biological activities two varieties O. (Fino Verde variety Genovese varieties). To this end, level oils, flavonoids phenols, as well antioxidant antifungal were me...

Monoterpenes, derived primarily from plants, are products of the isoprenoid biosynthetic pathway and function as chemical messengers with diverse functions. The biochemical bases for these activities are largely undefined. The Ras small GTPase superfamily of proteins consists of isoprenylated proteins that play key roles in signal transduction pathways known to regulate diverse cellular functio...

Abstract. Nighttime NO3-initiated oxidation of biogenic volatile organic compounds (BVOCs) such as monoterpenes is important for the atmospheric formation and growth secondary aerosol (SOA), which has significant impact on climate, air quality, human health. In SOA growth, highly oxygenated molecules (HOM) may be crucial, but their pathways role in have yet to clarified. Among monoterpenes, lim...

Plant derived oils have recently been found to be more effective in pharmaceutical sectors than synthetic goods since these plants contain physiologically active chemicals with a wide range of therapeutic effects. Essential oil, also known as essence, volatile etheric or aetheroleum, is complex mixture elements biosynthesised by living organisms, which particularly abundant aromatic plants. Thi...

Volatile organic compounds (VOCs) are emitted into the atmosphere from natural and anthropogenic sources, vegetation being the dominant source on a global scale. Some of these reactive compounds are deemed major contributors or inhibitors to aerosol particle formation and growth, thus making VOC measurements essential for current climate change research. This thesis discusses ecosystem scale VO...

Eddy covariance (EC) is the preferable technique for flux measurements since it is the only direct flux determination method. It requires a continuum of high time resolution measurements (e.g. 5-20 Hz). For volatile organic compounds (VOC) soft ionization via proton transfer reaction has proven to be a quantitative method for real time mass spectrometry; here we use a proton transfer reaction t...
