Abstract:
... To examine chemical composition and antioxidant activity as well as the in vitro α-amylase and pancreatic lipase inhibitory activities of the essential oil and various extracts of Juniperus phoenicea (J. phoenicea).Essential oil obtained by steam distillation were analyzed by gas chromatography-mass spectrometry technique. The antioxidant activity of the essential oil and various extracts of J. ph ...

Abstract:
... Essential oils of Algerian Juniperus phoenicea L. obtained from leaves and berries by hydrodistillation (HD) and from berries by Solvent Free Microwave Assisted Extraction (SFMAE) were investigated using both capillary GC and GC-MS techniques. The monoterpene hydrocarbons constituted the most prominent group of constituents (43.2-86.5 %) in the three essential oils with α-pinene (34.4-80.8 %) as t ...
