Saponins and Sapogenins from Brachiaria decumbens Stapf [PDF]
Journal of the Brazilian Chemical Society, 2002 Four steroidal saponins and three sapogenins were identified from aerial parts of Brachiaria decumbens. Their structures were established by chemical and spectroscopic means (¹H and 13C NMR, HMBC, HMQC) as 3beta-methoxy-lanost-9(11)-ene (1), diosgenin (2a), yamogenin (2b), 3-O-beta-D-glucopyranosyl-24(S)-ethyl-22E -dihydrocholesterol (3a), 3-O-beta-D ...

Phytotoxic Substance with Allelopathic Activity in [PDF]
Natural Product Communications, 2015 The grass Brachiaria decumbens becomes naturalized and quickly dominant in non-native areas. It was hypothesized that phytotoxic substances of plants may contribute to the domination and invasion of the plants. However, no potent phytotoxic substance has

Dynamique de croissance de Brachiaria decumbens et Digitaria decumbens
, 1990 Les dynamiques de croissance du Brachiaria decumbens et du Digitaria decumbens ont été appréhendées sous diverses formes au cours d'une année expérimentale (avril 1988-mai 1989) découpée en 8 périodes de 12 semaines de cycle végétatif. Une approche agronomique a permis d'établir un modèle de production intégrant successivement les facteurs temps et ...

Hepatogenous Photosensitization in Steer by Brachiaria decumbens [PDF]
Acta Scientiae Veterinariae, 2021 Background: Although the etiology of hepatogenous photosensitization has not yet been fully elucidated, it is known that hepatotoxic substances (saponins) present in grasses of the genus Brachiaria spp. are responsible for intoxication of several species, causing great economic losses in the whole world.

CHLOROPHYLL FLUORESCENCE IN Brachiaria decumbens AND Brachiaria ruziziensis SUBMITTED TO HERBICIDES [PDF]
Planta Daninha, 2017 ABSTRACT Different doses of herbicides can promote a differentiated physiological response in grasses of the same genus. This study has been proposed in order to evaluate physiological responses of B. ruziziensis and B. decumbens submitted to glyphosate and fluazifop-p-butyl. Treatments were distributed in a 2 x 6 factorial design with five repetitions,

Meiotic behavior of Brachiaria decumbens hybrids
Genetics and Molecular Research, 2015 Brachiaria decumbens is a forage grass of inestimable value for livestock in Brazil due to its production of good quality forage even when planted on acid and poor soils, although it is susceptible to pasture spittlebugs. Only one cultivar, cv. Basilisk, has been used as the pollen donor in crosses with Brachiaria ruziziensis since 1988 at Embrapa Gado

Experimental poisoning by Brachiaria decumbens in rabbits [PDF]
Pesquisa Veterinária Brasileira, 2018 ABSTRACT: Brachiaria spp. are important sources of forage for ruminants in Brazil, due to the easy cultivation, good resistance to drought, good adaptation to different soils and low maintenance cost. However, the ingestion of this grass has been related to photosensitization outbreaks in cattle and sheep with significant economic losses.
