This article describes the various chemical components as obtained from the oils in the leaves of Cymbopogon citratus using hydrodistillation and solvent-free microwave extraction methods. Furthermore, extractions of the oils were also carried out with a slight in pH variation and compared, "GC-MS evaluation of C. citratus (DC) Stapf oil obtained using modified hydrodistillation and microwave e...

The Lamiaceae family consists of a broad spectrum of medicinal plants involving Marrubium L. genus. Regarding the diverse pharmaceutical uses of the plants belonging to this genus, they can be considered as proper alternatives for chemical drugs having harmful effects. The present work aims to identify and characterize chemical compositions of the essential oils and volatiles from the aerial pa...

The volatile compounds from various parts of Echinops ilicifolius (Compositae) such as flowers, leaves and roots obtained by hydrodistillation (HD) and headspace solid-phase microextraction (HS-SPME) methods were subsequently analysed by GC and GC/MS and compared. Thirty-seven and 20 components of the flower of E. ilicifolius were characterized, representing 99.7% and 100.0% of the total compos...

The extraction of bioactive plant components, which belong to specialized metabolites, is carried out by conventional and novel methods. In this study, a classical (hydrodistillation, HD) technique (microwave-assisted water extraction, MAE) were used isolate free volatile compounds from nine Croatian Veronica taxa (family Plantaginaceae). Each these extracts consists lipophilic phase an aqueous...
