Outbreaks of hepatogenous photosensitization have been reported in ruminants grazing Brachiraria spp. Saponins are secondary metabolites present in that grass, and these substances are
related as toxic causing the disease. The objective of this study was to identify and quantify the variations of the saponin protodioscin content in green leaves of different Brachiraria
species/ecotypes. Samples of leaves were collected from 10 ecotypes of Brachiraria spp., from August 2009 to August 2010. Following the procedure of extracting saponins from the dried and
crushed leaves, the analysis was performed using HPLC-ELSD for identification and quantification of protodioscin. It was observed that the species B. decumbens has the highest concentration of
protodioscin (2.33% ± 0.54), B. brizantha var. Arapoty has the highest concentration (1.24% ± 0.44) between the B. brizantha ecotypes. Finally B. humidicola cultivars have the lowest concentrations ranging from 0.11 to 0.9%. These data confirm the observations of other researchers who cite B. decumbens as responsible for most cases of hepatogenous photosensitization. It can be concluded that the varieties of B. decumbens are those with the highest concentrations of protodioscin, followed by varieties of B. brizantha and varieties of B. humidicola. |
