| ABSTRACT The middle Rio Negro region is an interesting place to seek novel antimalarial compounds because of the traditional knowledge of the Amazon population in conjunction with the high biodiversity of the region. The objective of this work was to study the use of antimalarial plants in Barcelos, state of Amazonas, Brazil. Fifty-two local specialists from eight different communities were interviewed over one year. The identified plants were collected with the assistance of local specialists, classified to species level and deposited in herbarium. In total, 55 antimalarial plants were identified in use in the region, of which 16 had not been previously reported in other published studies. Many factors could be involved with the use of antimalarial plants... |

| The Brazilian State of Amazonas has a high incidence of Tuberculosis, 91.4 in 10,000 habitants (SESAU, 1994) and resistant strains of Mycobacterium tuberculosis are frequently being found in the region (SALEM et.al, 1990). These problems have been associated with side effects caused by the antibiotics used to treat Tuberculosis, which have in rum been associated with treatment non-compliance (PATTISAPU, 1984). To resolve this problem a cost effective alternative treatment for Tuberculosis with few or no side effects, needs to be found. Amazonas has an abundance of plants, many of which are used by the lay population for medicinal purposes. A survey was carried out in five towns of the region, interviewing patients receiving treatment for Tuberculosis, to... |

| There have been ethnoveterinary reports from around the world investigating plant usage in therapeutic protocols; however, there is no information regarding the ethnoveterinary practices in Brazilian Amazonia. The objective of this work was to register and document the ethnoveterinary knowledge of the inhabitants of the Island of Marajó, eastern Amazonia, Brazil. In the study, interviews were conducted with 50 individuals, with the application of semi-structured questionnaires that were quantitatively analyzed using descriptive statistic methods of frequency distribution. Use-value was calculated to determine the most important species. Samples of plants that were reported to have medicinal value were collected and identified by botanical classification.... |

| ABSTRACT Byrsonima crassifolia and B. coccolobifolia, popularly known as mirixis, muricis, mantecos or nances, are common fruit species in the Amazonian savannas. Their fruits are used in the preparation of juices and other beverages, while the other parts of the plants are used for different purposes in some indigenous communities. The aim of the present ethnobotanical study was to investigate the knowledge and traditional uses of mirixis in the Darora Indigenous Community, of the Makuxi ethnicity, in the São Marcos Indigenous Land, state of Roraima, northern Brazil. The knowledge on these species among the residents was analyzed considering their gender and age. A survey was carried out by means of semi-structured interviews with 60 respondents (36 men... |

| The ethanol extract from stem bark of Sacoglottis uchi Huber (popularly known as uchi in the Amazon Region) was submitted to chromatographic fractionation. The dichloromethane fractions provided the pentacyclic triterpene 3-oxo-friedelin (1). The dichloromethane:methanol fractions provided the pentacyclic triterpenes pseudotaraxasterol (2), lupeol (3), a-amyrin (4), betulin (5), and methyl 2ß,3ß-dihydroxy-urs-12-en-28-oate (6) and a mixture of the steroids sitosterol (7) and stigmasterol (8). Their chemical structures were determined by NMR spectroscopy and comparison with spectroscopic data from the literature. All compounds are described for the first time in this species. |

| ABSTRACT Ultraviolet B radiation has been described as a potential elicitor agent of the synthesis of secondary metabolites in plants. Thus, the present study aimed to investigate the production of betalains and total flavonoids, as well as the antioxidant activity, of Alternanthera sessilis, A. brasiliana, A. tenella and A. philoxeroides exposed to different periods of UV-B radiation (280-315 nm). Plants of these four species were exposed to UV-B radiation for 0, 2, 4, 6, and 8 hours, which amounts to 0, 10, 20, 30, and 40 J cm−2 of radiation, respectively. Significant increases in betacyanin and betaxanthin levels were observed in A. sessilis and A. brasiliana during the period of UV-B exposure, while no differences were observed for the others species.... |

| This ethnobotanical survey carried out with the Kaiowá and Guarani populations in the Caarapó Reserve (Mato Grosso do Sul, Brazil) showed that 34 plant species of 22 families with medicinal properties, are used for treating diverse pathologies. Local names in Portuguese and Guarani are provided, along with therapeutic indications, modes of preparation, and a description of the plant parts used. These folk-medicine plants have been mostly used for the treatment of influenza, abdominal pain, fever and rheumatism, and for wound healing. |

| ABSTRACT Ethnomedicine focuses on empirical and traditional knowledge of healing practices of different human groups, including the use of plants as medicine. We aimed to determine whether there is consensus regarding the use of plants in traditional medicine of Afro-descendant communities in Brazil, Europe and Africa. Data were obtained through interviews, walks-in-the-woods, participant observations and bibliographic searches. We analyzed similarities among data sets to determine whether there is convergence in the use of traditional medicinal plants among these communities considering that they share influence from African culture and a common spoken language (Portuguese). Similarities among communities were assessed through cluster analysis using... |

| O manjericão (Ocimum basilicum L.) é uma planta aromática de importância econômica no Brasil, muito usado como tempero na preparação de alimentos. É também utilizado para a obtenção de óleo essencial, importante na indústria de perfumaria. O objetivo deste experimento foi analisar o efeito de cinco lâminas de irrigação, bem como uma análise da viabilidade econômica da aplicação da irrigação na produção do manjericão. O experimento foi conduzido no período de março a outubro de 2007. As lâminas foram baseadas na evaporação do Tanque Classe A (ECA) sendo: 0, 50, 75, 100 e 150% ECA. As variáveis analisadas foram matéria seca das folhas e inflorescências, teor de óleo essencial, massa seca e comprimento de raízes. Foram calculadas a produtividade de óleo... |

| Species of the genus Mentha produce essential oils which are widely used in pharmaceutical and cosmetic industries. Current study evaluates the potential for in vitro propagation and estimates mass production of plantlets of Mentha species. Nine species (M. piperita, M. suaveolens, M. canadensis, M. longiflora, M. aquatica, M. arvensis, Mentha x gracilis, M. gracilis and M. spicata) were propagated with five successive 30-day subcultures in MS medium supplemented with NAA (0.05 µM) and BAP (4.4 µM). Shoots were rooted in MS with IBA, IAA or NAA (0.0; 0.25; 0.5; 2.5 or 5.0 µM). The rooted plantlets were finally acclimatized in a greenhouse. Studied species increased in multiplication rates between 4.2 and 9.0-fold per month. M. piperita, M. longiflora, M.... |

| The Achillea millefolium L. is a perennial herb with important antibacterial, antifungal, anti-inflammatory, antitumoral, and antioxidant properties. This research aimed to investigate the effect of shading (75%; black net) and nitrogen fertilization (0, 75 and 150 kg urea ha-1) on the nitrogen metabolism, essential oil yield and antimicrobial activity of A. millefolium at vegetative- and reproductive-stage. The evaluated parameters varied depending on the organ and the phenological stage of the plant considered. Overall, our findings indicated that shading decreased nitrogen assimilation. Decreased activities of nitrate reductase and glutamine synthetase were observed on shaded plants during reproductive and vegetative stages, respectively. Nitrate and... |
