Effect of dietary Senecio jacobaea and injected Senecio alkaloids and monocrotaline on guinea pigs.
The chronic toxicity of 10% dietary Senecio jacobaea (SJ) in guinea pigs was studied during a 365-d feeding trial. The SJ plant contains hepatoxic pyrrolizidine alkaloids (PA). The chronic lethal dose (LD100) of SJ for guinea pigs was 1,264 g/kg initial body weight or 526% of initial body weight with an average survival time of 279 d. No mortality was observed in the controls. The LD100 and sur...
متن کاملNatural hybridization between Senecio jacobaea and Senecio aquaticus: molecular and chemical evidence.
Hybridization is known to be involved in a number of evolutionary processes, including species formation, and the generation of novel defence characteristics in plants. The genus Senecio of the Asteraceae family is highly speciose and has historically demonstrated significant levels of interspecific hybridization. The evolution of novel chemical defence characteristics may have contributed to t...
متن کاملReproductive fitness of hybrids between Senecio jacobaea and Senecio aquaticus (Asteraceae)
Natural hybridization is increasingly recognized as an important process for the ecology and evolution of natural plant populations and species. There is a great need to initiate more studies based on natural populations in order to elucidate the possible role of hybrids in nature. The reproductive success of early generation hybrids can make or break hybrid lineages and may determine the genet...
متن کاملArtikel The toxicity of Senecio inaequidens DC .
INTRODUCTION Seneciosis is one of the most important plant poisonings in South Africa. Certain Senecio species contain toxic pyrrolizidine alkaloids (PAs) which, besides other toxicological effects, induce acute or chronic hepatotoxicity in livestock and man. In the genus Senecio the occurrence of the PAs senecionine, retrorsine and integerrimine is well known. Senecio latifolius, the most impo...
متن کاملA New Bezoxepine Derivative from Senecio desfontainei
Phytochemical investigation of the aerial parts of Senecio desfontainei afforded one new benzoxepine derivative, senecioside (1) along with eleven known compounds (2-12). Their structures were assigned from H and C NMR spectra, DEPT and 2D COSY, NOE, HSQC and HMBC NMR experiments. All these compounds were tested for antioxidant activity in the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scaven...
