Essential Oils Composition, Anticholinesterase and Antioxidant Activities of Pistacia atlantica Desf
Chemical composition and in vitro antioxidant and anticholinesterase activities of essential oils obtained from leaves and flowers of Pistacia atlantica were studied. GC/GC-MS analyses of the essential oils afforded twenty-two compounds from flower oil and thirty from leaf oil. The antioxidant activity of the essential oils was determined using -carotene-linoleic acid, DPPH • and ABTS • -scav...
PURPOSE Carrying out the chemical composition and antiproliferative effects against cancer cells from different biological parts of Artemisia herba alba. METHODS Essential oils were studied by gas chromatography coupled to mass spectrometry (GC-MS) and their antitumoral activity was tested against P815 mastocytoma and BSR kidney carcinoma cell lines; also, in order to evaluate the effect on n...
effects of mentha arvensis l. and mentha pulegium l. essential oils were investigated against oviposition deterrence, egg hatching and adults' mortality of callosobruchus maculatus f. essential oils were obtained by dry leaves that were subjected to hydrodistilation using a modified clevenger-type apparatus. all experiments were conducted at 25±1ºc, 65±5 % r.h. in the dark condition with 5...
The antimicrobial activity of essential oils and their components has been recognized for several years. Essential oils are produced as secondary metabolites by many plants and can be distilled from all different portions of plants. The recent emergence of bacteria resistant to multiple antibiotics has spurred research into the use of essential oils as alternatives. Recent research has demonstr...

Family Cupressaceae is the largest coniferous plant family. Essential oils of many species belonging to family Cupressaceae are known to have several biological activities specially antimicrobial activity. The essential oils from aerial parts of Calocedrus decurrens Torr., Cupressus sempervirens stricta L. and Tetraclinis articulata (Vahl) Mast. were prepared by hydrodistillation. The chemical ...
Modern medicine focuses on the hardware systems of the physical body (the hardware body) and has not accepted the concept of ‘software being’. However, making this shift enables a larger view of health, illness and pathology, enabling additional approaches to help patients get better. Historical thinking actually supports this step in thinking – as long as narrow attitudes that block ‘out of th...
