Clove basil (Ocimum gratissimum) extracts were obtained with supercritical CO2. Clove basil was cultivated using 0, 4, 8 and 12 kg/m(2) of organic fertilizer and was harvested in four seasons: winter, spring, summer and autumn, in the Southern Hemisphere. The extracts' global yields were determined at 40C and 150 bar for samples from all cultivation conditions and harvesting seasons. For selected samples, the extracts' global yields at 40C were determined for pressures of 100, 150, 200, 250 and 300 bar. The extracts were analyzed by gas chromatography-flame ionization detector. Antioxidant activity (AA) was assessed using the coupled reaction of beta-caroteneand linolenic acid. The extracts' global yields varied from 0.91 to 1.79% (dry basis), and the AAs varied from 62 to 84% compared with the control beta-carotene. Eugenol and beta-selinene were the major compounds. The relative proportion of eugenol varied from 35 to 60%, while the content of beta-selinene remained approximately constant (11.5-14.1%, area). The other substances quantified in the extracts were 1,8 cineole, trans-caryophyllene and alpha-selinene.

Com base em um corpus de vocabulário político constituído pelos jornais Folha de S. Paulo e O Estado de S. Paulo, analisados durante o ano de 1986 (amostragem sistemática de 30%), estudamos os neologismos formados por composição substantiva. Alguns substantivos, com função determinante, ocupam tão freqüentemente a segunda posição na composição por justaposição, que tendem a perder parte de seu significado e a adquirir um valor sufixal.

Disclosed are compounds of formulae (II) and (III), wherein R1 is other than hydrogen and the remaining substituents are as defined in the specification, processes for their preparation and pharmaceutical compositions containing them. The compounds are capable of inhibiting acetylcholinesterase, and are useful in the treatment of pathologies associated with cholinergic transmission, such as memory related disorders, neurodegenerative disorders such as Alzheimer's Disease, Myasthenia Gravis and intoxication induced by chemical agents.
