The aim of this study was to evaluate the potential anticancer properties and modulatory effect of selected Aloe vera (A. vera) active principles on antioxidant enzyme activities. Thus, three anthraquinones (Namely: aloesin, aloe-emodin and barbaloin) were extracted from A. vera leaves by supercritical fluid extraction and subsequently purified by high performance liquid chromatography. Additio...

Qualitative and quantitative chemical composition, activity against bacteria, yeasts and moulds and antioxidant activity of two variants (HV400 and HV3200) of hydrolates from dried lavender flowers (Lavandula angustifolia) were determined. The main chemical compounds were linalool (39.2% HV400, 29.0% HV3200), α-terpineol (7.1% HV400, 12.7% HV3200), borneol (4.8% HV400, 9.3% HV3200) and terpinen...
