dc.description.abstract	Humulus lupulus L. is a species in the Cannabaceae family. Hop, as it is commonly known, is a perennial, dioecious and normally diploid (2n = 20) herbaceous plant [1]. It is in beer production that hops have their greatest economic value at the international level. Due to the production of compounds with bactericidal action, in particular against Gramnegative bacteria, the hops came to solve problems related to the conservation of beer [2]. In addition Hops contain compounds that confer sedative, diuretic and antiarthritic properties [3]. In the ethnobotanical use, the dried flowers were used in pillows called "hop pads", to combat insomnia [4]. The use of dried and green hop inflorescences for diuretic uses and disorders of the digestive tract, were verified in the Montesinho park area [5]. In China, alcoholic extracts of hops were used to treat leprosy, tuberculosis and dysentery [2]. Its use in infusions as a tonic, since the middle Ages where it considered a medicinal herb [6]. The results obtained show a certain similarity in the monoterpene component, with β-myrcene as the major compound (more than 64% in cultivar and spontaneous samples) and notorious differences in the sesquiterpene component, evident in cases of α-humulene (12% in cultivars, 0.2% and in spontaneous) and trans-β-farnesene (not detected in cultivars, 9% in spontaneous). Also important is the richness of the sesquiterpene component in spontaneous clone, in particular in the oxygenated compounds. This profile, of both cultivar and spontaneous, shows potential for antiseptic effects in the digestive tract, especially when these are associated with bacteria such as Helicobacter pylori [7], which will be in agreement with ethnobotanical uses of Hop. Since there is spontaneous hops in a large part of Portugal, the collection and analysis of the aromas of these hops may lead to the development of new and more fragrances, with interest in different areas, like beer production or cosmetics. The volatile components extracted from spontaneous hops collected in the Bragança area were analyzed and compared with those of commercial varieties.	pt_PT
