Culinary herbs and spices have long been considered essentially as flavor enhancers or preservatives, with little attention given to their potential health-promoting properties. Nevertheless, recent research has shown them to be significant dietary sources of bioactive phenolic compounds. Despite noteworthy efforts performed in recent years to improve our knowledge of their chemical composition, a detailed phenolic profile of these plant-based products is still lacking. In the present work, antioxidant activities and phenolic composition of five herbs and spices, namely caraway, turmeric, dill, marjoram and nutmeg, have been studied. The use of liquid chromatography coupled to LTQ-Orbitrap mass spectrometry enabled the identification of up to 42 phenolic...

Chemical composition and anthelmintic activity in vitro of the essential oil of Mentha piperita: preliminary data. Repositório Alice
MESQUITA, R. J. M.; MONTEIRO, J. P.; CATUNDA, F. E. A.; TEIXEIRA, M..
Abstract: Research towards plant compounds with activity against worm parasites has been carried out for a number of decades; however it is especially important now when drench resistance has compromised the effectiveness of present control methods. In this study we characterized the composition of Mentha piperita essential oil and evaluated its anthelmintic effect against developmental stages of trichostrongylids from naturally infected goats (95% Haemonchus contortus and 5% Trichostrogylus spp.) through the egg hatch and larval development assays. The major constituent of the tested substance quantified by gas chromatography was menthol (58.35%). The lowest concentration of essential oil with 100% efficacy in all in vitro tests against caprine...
