Connecting landscape conservation and management with traditional ecological knowledge: does it matter how people perceive landscape and nature? IPB - Escola Superior Agrária
Carvalho, Ana Maria; Frazão-Moreira, Amélia; Ramos, Margarida Telo.
Ethnobotanical surveys conducted in Trás-os-Montes highlighted a renewed interest in cultural and heritage values of landscapes. Landscape diversity is mostly based on traditional ecological knowledge (TEK) and practices that, since a long time ago, interacted with natural processes. Rural contexts face social and economical constraints and landscapes are change accordingly. This poster aims to describe recent landscape changes at a local scale and people’ perceptions. Moreover, to discuss local conceptions as important tools for landscape conservation and management

Diversity and selection of wild food plants in six regions of Northwestern Iberian Peninsula (Spain and Portugal). IPB - Escola Superior Agrária
Pardo de Santayana, Manuel; Tardio, Javier; Carvalho, Ana Maria; San Miguel, Elia; Blanco, Emilio; Morales, Ramón.
We discuss and compare the traditional knowledge and use of wild edible plants in six rural regions of the northwest of the Iberian Peninsula. The data indicate that a high percentage of species are used in most regions (15 species are used in 5 regions). According to the similarity of the species gathered, the six regions can be grouped in two clusters. Therefore, affinity seems to be linked to closeness. The Portuguese region is the most dissimilar due to a very high number and frequency of wild condiments.

Du savoir-faire à la connaissance des plantes: pratiques ancestrales et savoirs modernes au sein du monde rural portugais IPB - Escola Superior Agrária
Frazão-Moreira, Amélia; Carvalho, Ana Maria; Martins, Elisabete.
Aux villages du nord-est portugais, dans les mémoires d’enfance des hommes, l’imaginaire des plantes est associé aux jeux et travaux de la vie quotidienne d’autrefois. Les femmes évoquent aussi les histoires de leurs grand-mères, des histoires où les plantes jouent un rôle fondamental aux cérémonies religieuses et festives du village, guérissent et préviennent les maladies et protègent la famille et le foyer. Dans cet imaginaire les plantes sont perçues comme indispensables à la survie, au loisir et à un rapport étroit avec le milieu naturel et le surnaturel. Ce texte se conçoit à partir de trois questions : Est-ce que les changements socio-économiques récents et le rapprochement du rural au quotidien urbain ont modifié l’imaginaire des plantes ? Est-ce...

Folk medicine of Trás-os-Montes (Portugal). Traditional uses and bioactive compounds of six common medicinal species IPB - Escola Superior Agrária
Carvalho, Ana Maria; Barros, Lillian; Ferreira, Isabel C.F.R.; Frazão-Moreira, Amélia.
Ethnobotanical surveys conducted in north-eastern Portugal along several years (2000-2009) reported plant knowledge and use of almost 150 wild species used in folk medicine. This poster documents traditional knowledge and reports the first approach to the antioxidant potential evaluation of six of these species with particular cultural significance, accessed by biochemical assays used as models for the lipid peroxidation damage in biomembranes. Bioactive compounds such as phenolics, flavonoids, vitamin C and vitamin E were also determined.

From famine plants to tasty and fragrant spices: three Lamiaceae of general dietary relevance in traditional cuisine of Trás-os-Montes (Portugal) IPB - Escola Superior Agrária
Barros, Lillian; Carvalho, Ana Maria; Ferreira, Isabel C.F.R..
The chemical composition and nutritional value of three Lamiaceae often used as spices in Portuguese traditional cuisine: Ground ivy (Glechoma hederaceae L.), oregano (Origanum vulgare subsp. virens (Hoffmanns. & Link) Ietswaart) and mastic thyme (Thymus mastichina L.) were determined. Chemical composition evaluation included moisture, total fat content, crude protein, ash, carbohydrates, and nutritional value determination. The macronutrient profile revealed that these spices are rich sources of carbohydrates and that an edible portion of 100 g assures, on average, 161 Kcal. The composition in individual sugars was determined by high performance liquid chromatography coupled to a refraction index detector (HPLC/RID), being this methodology completely...

In vitro antioxidant properties and characterization in nutrients and phytochemicals of six medicinal plants from the Portuguese folk medicine IPB - Escola Superior Agrária
Barros, Lillian; Oliveira, Sónia; Carvalho, Ana Maria; Ferreira, Isabel C.F.R..
Traditional ethnomedical use of plants is recognized as an important potential source of compounds used in mainstream medicine. Herein, the in vitro antioxidant properties, nutrients and phytochemical composition of six medicinal plants widely used in the north-eastern Portuguese region were evaluated. The antioxidant activity was screened through: radical scavenging effects, reducing power, and inhibition of lipid peroxidation in brain homogenates. Nutrients and phytochemical characterization included determination of sugars by HPLC-RI, fatty acids by GC-FID, tocopherols by HPLC-fluorescence, phenolics, flavonoids, carotenoids and ascorbic acid, by spectrophotometric techniques. Rubus ulmifolius flowers revealed the highest antioxidant activity, and the...

Lamiaceae often used in Portuguese folk medicine as a source of powerful antioxidants: vitamins and phenolics IPB - Escola Superior Agrária
Barros, Lillian; Heleno, Sandrina A.; Carvalho, Ana Maria; Ferreira, Isabel C.F.R..
Three Lamiaceae often used in Portuguese folk medicine: Ground ivy (Glechoma hederaceae L.), oregano (Origanum vulgare subsp. virens (Hoffmanns. & Link) Ietswaart) and mastic thyme (Thymus mastichina L.), revealed to be good sources of powerful antioxidants such as vitamins (ascorbic acid and tocopherols) and phenolics. The HPLC methodology developed for tocopherols analysis proved to be, after validation assays, sensitive and accurate. Ground ivy showed the highest levels of vitamins: ascorbic acid (168 2 mg/g dry weight) and tocopherols (3692 57 mg/g dry weight). The phenolics extraction was optimized using mastic tyme, and different conditions (water and ethanol:water 50% v/v, 30 min at 25 C and boiling temperature; ethanol and methanol, 24 h...

Leaves, flowers, immature fruits and leafy flowered stems of Malva sylvestris: a comparative study of the nutraceutical potential and composition IPB - Escola Superior Agrária
Barros, Lillian; Carvalho, Ana Maria; Ferreira, Isabel C.F.R..
Malva sylvestris is widely used in Mediterranean and European traditional medicine and ethnoveterinary for the treatment of external and internal inflammation, as well as injuries. Moreover, its use is not only limited to therapeutic purposes; but also the species is locally regarded as a food wild herb. Considering that antioxidants and free radical scavengers can exert also an anti-inflammatory effect, the extracts of different parts of the medicinal/edible plant M. sylvestris (leaves, flowers, immature fruits and leafy flowered stems) were compared for their nutraceutical potential (antioxidant properties) and chemical composition. Particularly, mallow leaves revealed very strong antioxidant properties including radicalscavenging activity (EC50 = 0.43...

Lipophilic and hydrophilic antioxidants, lipid peroxidation inhibition and radical scavenging activity of two Lamiaceae food plants IPB - Escola Superior Agrária
Fernandes, Ângela S.F.; Barros, Lillian; Carvalho, Ana Maria; Ferreira, Isabel C.F.R..
Medicinal and aromatic plants are highly prized all over the world. According to local cuisine and pharmacopoeias, they used to be important as dietary supplements, providing bioactive compounds. Herein, we describe lipophilic (fatty acids, tocopherols and carotenoids) and hydrophilic (ascorbic acid, sugars and phenolic compounds) antioxidants, lipid peroxidation inhibition and free radical scavenging activity in aerial parts of two Lamiaceae species (Mentha pulegium and Thymus pulegioides). M. pulegium gave the highest antioxidant properties (EC50<0.56 mg/mL), which is in agreement with its highest content in tocopherols, mainly alpha-tocopherol (69.54 mg/100 g), ascorbic acid (7.90 mg/100 g), reducing sugars (7.99 g/100 g) and phenolics. The presence...

Local ecological knowledge also ‘comes from books’: cultural change, landscape transformation and conservation of biodiversity in two protected areas in Portugal IPB - Escola Superior Agrária
Frazão-Moreira, Amélia; Carvalho, Ana Maria; Martins, Elisabete.
The study of social and economic change and the consequent landscape transformation in the Parque Natural de Montesinho and theParque Natural de Douro Internacional (two protected areas of the Northeastern Portugal) allows us to discuss the ambivalent relation between the political aims of biodiversity preservation and the social reality in protected rural areas. Ethnographic research on plant use and nature discourses, together with an analysis of social differentiation (in terms of age, gender and schooling) of ethnobotanical knowledge show us how local people dynamically combine traditional and orally-transmitted knowledge with popular or then scientific exogenous ecological knowledge, especially that learned from the media and books. These data also...

Bettencourt, E.; Dias, S.; Rocha, F.; Lopes, V. R.; Barata, Ana Maria; Carvalho, Ana Maria.
For more than three decades the Portuguese Gene Bank (INRB.IP/BPVG) has been collecting, documenting, characterising and conserving biological diversity and plant genetic resources (PGR) of crops and species, which include medicinal and aromatic plants (MAP) traditionally used in Portugal. Over a four-year period, the BPVG and other 8 national partners were engaged in a broader research project (Agro 34) conducted in different Portuguese regions aiming to select MAP target taxa, considering important factors such as ecogeographic distribution, biological and sociocultural importance, genetic distinctiveness, potential economic use, threat of genetic erosion, current conservation status, traditional ecological knowledge (TEK) status, cost, feasibility and...

Medicinal plants and folk uses in Trás-os-Montes (Portugal). An overview of phytochemical properties and bioactive compounds potential IPB - Escola Superior Agrária
Carvalho, Ana Maria; Barros, Lillian; Ferreira, Isabel C.F.R..
Ethnobotanical surveys conducted in north-eastern Portugal reported plant knowledge and uses of several wild species in folk medicine based on field studies using ethnographic methodologies. Taking advantage of a multidisciplinary team, besides botanical inventories and sociocultural and anthropological studies, we set out applied phytochemical research on locally used medicinal plants (more frequently cited, i.e. frequency of citation > 50%) that have special cultural significance. Experimental phytochemical research points to pharmacological effects that confirm the importance of the empirical use of these species and their contribution to a good health condition.

Persistence of wild food and wild medicinal plant knowledge in a North-Eastern region of Portugal IPB - Escola Superior Agrária
Carvalho, Ana Maria; Morales, Ramón.
Today, the geographical and social conditions that led to the isolation of some European regions are no longer prevalent, and so changes in the cultural, economic and political contexts of plant use in these areas are coming faster and faster. The current reduction in the human population, due to out-migration and a general drop in the birth rate, and the abandonment of agriculture have been critical for rural areas and ways of life and have promoted the loss of cultural traditions. How these changes are affecting the system of local knowledge of plant resources and the maintenance of traditional plant use practices are some of the questions addressed in this chapter, based on research in such a region of northeastern Portugal. We documented local...

Plantas aromáticas e medicinais e conhecimento etnobotânico em Trás-os-Montes (Portugal): recolha de usos e saberes em novos contextos rurais IPB - Escola Superior Agrária
Castro, Andreia; Claro, Sandra; Ramos, Margarida Telo; Barros, Lillian; Carvalho, Ana Maria.
O uso de plantas aromáticas e medicinais (PAM) tem larga tradição em Trás-os-Montes. Vários estudos etnobotânicos mostram que até há bem pouco tempo o conhecimento e uso de PAM eram domínio das pessoas mais velhas, residentes em meios rurais e sobretudo das mulheres, principais responsáveis pela transmissão de saberes e práticas. Neste trabalho pretende-se confirmar a percepção actual do mundo vegetal e caracterizar os conhecimentos sobre PAM e respectivos usos nesta região portuguesa.
