1. Development of diet cereal bar sweetened with stevia leaves pre-treated with ethanol
Abstract The objective of this work was to perform the ethanolic pretreatment of stevia leaves from the plant Stevia UEM-13 line and to characterize its physical-chemical properties aiming its use as a sweetener in the development of a diet cereal bar. The same formulation of the cereal bar with stevia leaves without pretreatment was elaborated for comparati

2. Comparison of total phenol content and antioxidant activity of herbal infusions with added Stevia reabaudiana Bertoni
Abstract Antioxidant capacity (AC) was determined by the ABTS method and DPPH, and total phenol content (TPC) in dehydrated plant material, in infusions and in residues (plant material after preparing the infusion) of white, black, red, green, spearmint, stevia, lemon grass and chamomile teas to which stevia leaves were added or not added; addition of proces

5. Anatomical characters and chemical profile of leaves of three species in Lauraceae family
ABSTRACT The Lauraceae family is widely distributed in tropical and subtropical climates, has more than 2500 species and in the taxonomic point of view, it is one of the most difficult families to identify species. The aim of this study was to analyze the leaf anatomy of three species of Lauraceae (Ocotea indecora (Schott) Mez, Nectandra barbellata Coe-Teix.

6. Leaf anatomy of Protium ovatum and its antiproliferative potential in cervical cells
ABSTRACT The aim of this study was to analyze the morphology and anatomy of the leaves of Protium ovatum Engl., Burseraceae, and verify the antiproliferative activity in cervical cells. For anatomical analysis, the leaf samples were fixed in formol, acetic acid, alcohol 70, dehydrated, included in hydroxyethyl methacrylate and sectioned at a thickness of 5�

7. Evaluation of beetroot (Beta vulgaris L.) leaves during its developmental stages: a chemical composition study
Beetroot leaves (Beta vulgaris L.) are commonly cut off and discarded before using its bulb due to lack of knowledge of how to use them. Aiming at using these leaves, in the present study, in natura and dehydrated beetroot leaves were chemically characterized in terms of fatty acid composition, proximate composition, minerals, total phenolic compounds (TPC),

8. Evaluation of hydration indexes in kale leaves
Hydration indexes are practical variables for quantifying plant water stress and can be useful for agronomic purposes. Three adapted hydration indexes based on relative water content, volumetric hydration, and leaf turgor pressure were evaluated in kale (Brassica oleracea var. acephala) leaf segments. Relative water content and volumetric hydration were meas

9. Composicao e valor nutritivo da farinha de folhas de rami para animais monogastricos.
O objetivo desta pesquisa foi estudar a composicao e o valor nutritivo da farinha de folhas de rami (Boehmeria niveia, Gaud.). Utilizou-se o rato (Ratus norvegicus) como modelo experimental. Determinacoes quimicas revelaram macronutrientes e minerais em excesso para o rato em crescimento, mas deficiencia de metionina, fosforo e cobre. A farinha, complementad

10. Oviposition activity of Aedes aegypti L. (Diptera: Culicidae) in responseto different organic infusions
The present study investigates new sources of infusion as an oviposition attractant for Aedes aegypti L. Infusions with fetid and non-fetid odors were compared as an oviposition stimulant. Traps baited with infusions of dehydrated cashew leaves (Anacardium occidentale), potato peels (Solanum tuberosum) and graminea (Panicum maximum) were compared as attracta

11. Optimization of the carrot leaf dehydration aiming at the preservation of omega-3 fatty acids
The carrot leaf dehydration conditions in air circulation oven were optimized through response surface methodology (RSM) for minimizing the degradation of polyunsaturated fatty acids, particularly alpha-linolenic (LNA, 18:3n-3). The optimized leaf drying time and temperature were 43 h and 70 ºC, respectively. The fatty acids (FA) were investigated using gas

12. Anatomia de folhas e raízes de Aechmea lindenii (E. Morren) Baker var. lindenii (bromeliaceae)
Aechmea lindenii (E. Morren) Baker var. lindenii (Bromeliaceae-Bromelioideae) ocorre em restingas e Floresta Pluvial de Encosta Atlântica em Santa Catarina e Nordeste do Rio Grande do Sul, BR. Pode ser encontrada total ou parcialmente exposta à irradiação solar e em distintas formas de vida - terrícola, rupícola e epifítica. Apresenta variações morf
