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 کاملPoisoning by the volatile oils in childhood.
The volatile oils play an important part in accidental poisoning in childhood, as can be seen from the figures quoted in a recent review (Craig and Fraser, 1953). The purpose of the present paper is to draw attention to the dangers of this form of poisoning, on which the recent literature is scanty, to suggest measures for its treatment and control, and to consider any points which may be appli...
متن کاملGenome elimination during microsporogenesis in two pentaploid accessions of Brachiaria decumbens (Poaceae).
Polyploidy is a prominent and significant force in plant evolution, taking place since ancient times and continuing until today. Recent cytogenetic studies in the genus Brachiaria using germplasm collected from wild African savannas in the 1980s revealed that most species and accessions within species are polyploid. Diploid, tetraploid, and pentaploid accessions have been found. We found asynch...
متن کاملA Parthenogenesis Gene Candidate and Evidence for Segmental Allopolyploidy in Apomictic Brachiaria decumbens
Apomixis, asexual reproduction through seed, enables breeders to identify and faithfully propagate superior heterozygous genotypes by seed without the disadvantages of vegetative propagation or the expense and complexity of hybrid seed production. The availability of new tools such as genotyping by sequencing and bioinformatics pipelines for species lacking reference genomes now makes the const...
