Saponins and Sapogenins from Brachiaria decumbens Stapf
Quatro saponinas esteroidais e três sapogeninas foram identificadas das partes aéreas de Brachiaria decumbens. As estruturas desses compostos foram estabelecidas através de métodos químicos e espectroscópicos (RMN de H e C, HMBC, HMQC) como 3 -metóxi-lanost-9(11)-eno (1), diosgenina (2a), iamogenina (2b), 3-O-D-glicopiranosil-24(S)-etil-22E-deidrocolesterol (3a), 3O-D-glicopiranosil-24(R)-etil-...
متن کاملPhotosensitisation and crystal-associated cholangiohepatopathy in sheep grazing Brachiaria decumbens.
Two outbreaks of photosensitivity and jaundice in sheep grazing the grass, Brachiaria decumbens. In West Java in 1983 and 1983 and 1990 are described. Aggregates of acicular clefts and crystals were present in bile canaliculi, bile ducts, Kupffer cells, hepatocytes and in kidney tubules. The number of crystals increased with the length of exposure to the plant and sheep that died had the larges...
متن کاملTiller density and tillering on Brachiaria brizantha cv. Marandu pastures inoculated with Azospirillum brasilense
The objective of this study is to verify the population density and the dynamics of tillering in the Marandu palisade grass sward subjected to nitrogen (N) fertilization strategies, characterized by the N supply via urea or bacterial inoculant (Azospirillum brasilense). The treatments comprised of four nitrogen fertilization strategies: (A) Without fertilization, (B) 80 kg N/ha, (C) inoculant (...
متن کاملIngestive Behavior of Heifers Supplemented with Glycerin in Substitution of Corn on Brachiaria brizantha Pasture
The objective was to evaluate the ingestive behavior of crossbred heifers finished on a Brachiaria brizantha cv. Marandu pasture receiving four levels of glycerin in their supplementation. Thirty-six crossbred heifers with average initial weight of 264.83±3.83 kg and 20 months of age were distributed into a completely randomized design with four treatments and nine replications: control (0%), 4...
متن کاملMorphogenetic characteristics of three Brachiaria brizantha cultivars submitted to nitrogen fertilization.
This study aims to evaluate the morphogenetic characteristics of three cultivars of Brachiaria brizantha subjected to nitrogen fertilization. The design was a randomized block in factorial arrangement 4x3; three cultivars of B. brizantha - Marandu, Piatã, Xaraés and four nitrogen levels - 0, 80, 160 and 240 kg/ha, with three replications. The experimental units consisted of plastic pots filled ...
