The aim of this study was to investigate the main volatiles and polyphenolic compounds in hydrosols extracted from three Romanian Lamiaceae plants, sage (Salvia officinalis), rosemary (Rosmarinus officinalis) lavender (Lavandula angustifolia) by steam distillation. antioxidant acetylcholinesterase inhibition capacity were assessed for their further use as biopesticides. results have shown that ...

The extensive research activity on sol-gel processing of silica glass has been reviewed by several authors [l-4]. The typical alkoxide route to silica sols comprises the catalyzed reaction of tetraethoxysilane (TEOS) and water in a mutual solvent. The TEOS alkoxy groups hydrolyze to form silanol monomers which condense and crosslink to form the silica gel network. The nature of the sol and the ...

Garden rose, Rosa hybrida, is primarily used for decoration and has a wide range of growing area, contrary to R. damascena that limited area distribution (Turkey Bulgaria), yet it extensively commercial production valuable expensive rose oil. Since the content essential oil in petals low (0.03–0.04%), its quite limited; however, during this process, significant amount hydrosol obtained as secon...

Red ginger is known as one of the medicinnal and aromatic plants that have high value in form essential oils. The distillation red oils required large amounts water, then most water was disposed wastewater. This wastewater hydrosol, which still contains a small amount secondary metabolites such zingiberene geraniol. These compounds were considered to potential be utilized cosmetic products foot...

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...
