| Saponins are natural compounds able to form abundant foam, a desirable quality required in some chemical, foods, cosmetic and pharmaceutical processes. Ilex paraguariensis A. St. Hil. (Aquifoliaceae) known as mate, is a South American widely cultivated specie due to the preparation of a tea-like beverage from its leaves. Moreover, its green fruits are a rich source of non-toxic and very low haemolytic saponins. In this study, mate saponin fraction (MSF) was evaluated as a foam former, focusing on its foamability, foam lifetime, and film drainage in the presence of different electrolytes (ionic strength I = 0.024 M). Sodium dodecyl sulphate (SDS) and polysorbate 80 (Poly-80) were used as reference surfactants. The critical micelle concentration (CMC), the... |

| Este trabalho estudou, por meio de coleções de herbários, os representantes arbóreos da ordem Celastrales sensu Cronquist, encontrados na bacia do rio Tibagi, estado do Paraná, Brasil. Esta bacia hidrográfica, subdividida em três zonas de norte para sul, baixo Tibagi (BT), médio Tibagi (MT) e alto Tibagi (AT), apresenta diferentes condições ambientais e tipos de vegetação ao longo de sua extensão. A ordem Celastrales está representada na bacia estudada por 15 espécies arbóreas, pertencentes às famílias Aquifoliaceae, Celastraceae e Icacinaceae. Icacinaceae conta com apenas duas espécies, Citronella gongonha e C. paniculata, sendo a primeira distinta pelo ovário glabro e folhas geralmente com espinhos. Aquifoliaceae contém seis espécies: Ilex brasiliensis,... |

| In the state of Rio Grande do Sul, Brazil, yerba mate (Ilex paraguariensis A. St.-Hil.) is an economically and culturally important species. Because of the difficulty in obtaining plantlets from seeds, micropropagation has emerged as an alternative that could increase production. This work aimed to evaluate the effect that treatment with 6-benzyladenine (BA), at concentrations of 2.2, 8.9, and 20 µM and associated with naphthaleneacetic acid (NAA, 0.5 µM), has on the in vitro growth and leaf emission of I. paraguariensis nodal segments cultivated in 0.5 X Murashige and Skoog (MS) medium or 0.5 X Woody Plant Medium (WPM). The most efficient treatment was MS medium with 8.9 µM BA+NAA, in which I. paraguariensis presented greater shoot elongation and higher... |

| Maté (Ilex paraguariensis A. St.-Hil.) is a native plant from southern Brazil and a raw material for beverages. To research on population variability of the species, we compared leaf morphology of three populations from Mato Grosso do Sul (MS), Paraná (PR) and Santa Catarina (SC) States. Lamina measurements included area (A), perimeter (P), length (l), maximum width (w), distance between maximum width and lamina base (dw), base angle (BÂ), biomass (m), and the indexes: relative distance of maximum width (dw/l), ratio length/width (l/w), relative perimeter (RP= P / (l + w), rectangular area index (RAI = A / (l x w)) and leaf mass/area (m/A). We verified differences among populations on A (MS<PR=SC), l (MS<PR=SC), w (MS<PR=SC), RAI (MS=PR>SC) and... |
