senecio burtonii/potassium

The present study assessed the safety/toxicity of Senecio scandens, a well-known Chinese herb that is used as an anti-inflammatory, antibiosis, and antipyretic drug. A 90-d subchronic oral toxicity study of S. scandens was performed in Wistar rats. The extract of S. scandens was administered orally

(+/-)-[3,5-14C]Trachelanthamidine and (+/-)-[5-3H]isoretronecanol, which are diastereomers, were prepared from potassium [14C]cyanide and [5-3H]proline, respectively. These compounds and [1,4-14C]putrescine were administered to Senecio riddellii plants resulting in the formation of labeled

Alien invasive plants are capable of modifying ecosystem function. However, it is difficult to make generalisations because impacts often appear to be species- and site-specific. In this study, we examined the impacts of seven highly invasive plant species in NW Europe (Fallopia japonica, Heracleum
