As dioscoreáceas constituem uma importante fonte alimentar e estão distribuídas nas regiões tropicais e subtropicais de todo o mundo. O objetivo desta pesquisa foi realizar um estudo etnobotânico sobre as variedades de cará (Dioscorea spp.) cultivadas por agricultores de oito municípios da Baixada Cuiabana, em Mato Grosso, com o intuito de verificar as espécies mantidas por eles e suas diversidades, nomes populares das variedades e o sistema de produção da cultura como: preparo das túberas-sementes, manejo da cultura, preparo do solo, plantio, tratos culturais e comercialização. Foram entrevistados 48 agricultores que cultivam o cará e anotados os nomes populares que estes dão às variedades do tubérculo. Foram encontradas três espécies: Dioscorea alata, D. trifida e D. bulbifera. O cultivo do cará é feito no sistema de ?roça de toco?. O preparo das túberas-sementes varia de acordo com cada espécie, sendo que, das 3 espécies encontradas, 55% são plantadas partidas e 45% inteiras. A organização e destino da produção acontecem nas comunidades, onde grande parte é destinada à alimentação familiar e o excedente é para a venda direta para consumidores ou via intermediários e aqueles que produzem exclusivamente para a venda. The yam is an important food source and are distributed worldwide in tropical, subtropical and temperate regions. The objective of this research was to conduct an ethnobotanical study on yam (Dioscorea spp.) varieties grown by farmers from eight municipalities of the Baixada Cuiabana, in Mato Grosso State, in order to verify the species kept by them and their diversity, popular names of the varieties and the crop?s production system, such as: seed tubers management, crop management, soil tillage, planting, cultivation and marketing. We interviewed 48 farmers, taking note of the popular names given to the yam varieties. Three species were found in the studied area: Dioscorea alata, D. trifida and D. bulbifera. The cultivation of yams is done on a "slash and burn" agriculture system. The preparation of the seed tubers varies with each species, whereas 55% are planted after being cut and 45% as whole tubers. The organization of production and destination occur in the communities, where most of it is destined for the families own consumption and the surplus is for sale directly to consumers or via intermediaries.

Lipids are important components of coffee beverage flavor and aroma. Coffee oil is rich in diterpens of the kaurane family, mainly cafestol (C20H28O3) and kahweol (C20H26O3), which have increasingly received attention in recent years due to their physiological effects in human health. However, few studies have been conducted on the effects of the genetic variability for those lipids in Coffea arabica. In this work we initiate the characterization of cafestol and kahweol in different cultivars of Coffea arabica, growing in the same edaphoclimatic conditions. Mature coffee fruits from cultivars Catuaí, Icatu and three Catucaí derived the cultivars IPR 100, IPR 102 and IPR 106. They were harvested at the Agricultural Field Station of the Coop COCARI, Mandaguari, Paraná, Brazil, from May to July 2009. Although the time of harvesting was according to the maturation of each cultivar, harvesting and post-harvesting conditions were the same for all cultivars. The five samples were subjected to medium roasting for 8 to 11 minutes at 200-210 °C, until the degree of roasting light/media (L* around 28). The extraction of diterpens was carried out in green or roasted coffee by direct saponification with KOH, extraction with terc-butyl methyl ether, and clean up with water. A reverse-phase HPLC column with isocratic elution with acetonitrile/water (55/45 v/v) was used for detection and quantification of kahweol at 290 nm and cafestol at 220 nm. In green beans, the level of kahweol was higher than cafestol, for all three IPR cultivars. Meanwhile, the inverse was observed for green beans cultivars Catuaí and Icatu, where cafestol levels were higher than kahweol. The higher levels of kahweol in relation to cafestol were again observed in roasted coffee of the three IPR cultivars. In cultivars Icatu the values for kahweol and cafestol were similar (635 and 683 mg/100 g, respectively). The highest levels of kahweol were observed in cultivar IPR 106 (1096 mg/100 g). The cultivar IPR 102 showed the highest level of cafestol (394 mg/100g). Association of this data with gene expression profile can be useful to find genes involved in cafestol and kahweol metabolism as well as to develop molecular markers for diterpens in coffee.
