[Calendula arvensis L. Impact of saponins on toxicity, hemolytic effect, and anti-inflammatory activity].

The study of the chemical composition of Calendula arvensis var. eu arvensis Maire reveals the presence of saponins. These saponins confer a haemolytic property on the plant. In our work we have, first determined the saponin responsible for the haemolytic property; and then we have studied the impact of the saponins on the acute toxicity and the anti-inflammatory activity induced by carrhageenin oedema.
