A comparison of polyphenolic content, antioxidant activity and insecticidal properties of Jatropha species and wild Ricinus communis L. found in Mauritius

Abstract

This study was able to demonstrate that Jatropha species as well as R. communis growing in Mauritius possess antimicrobial, phytochemical and insecticidal properties.

Assessment of Antioxidant and Cytoprotective Potential of Jatropha (Jatropha curcas) Grown in Southern Italy

“…The leaf extracts of Jatropha curcas L. are also rich in phenolic compounds and tartaric acid ester derivatives (Table 2), which further contribute to the health promoting properties of this plant. The total amount of phenolic compounds are in line with the amounts detected in other water extracts of jatropha plants collected in different seasons [47], but are obviously inferior to the one obtained in organic solvent, where the total amount is notoriously higher than water extract [48,49,50,51]. The analyses of enzymatic and non-enzymatic antioxidants results show that in Jatropha curcas L. leaves there are remarkable amounts of these active components, allowing us to hypothesize a direct role in the ability of the plant to resist environmental stresses and improve survival potentiality in the new habitat.…”

In Vitro Evaluation of Anthelmintic Efficacy of Some Plant Species Possessing Proteinases and/or Other Nitrogenous Compounds in Small Ruminants

“…Bidens pilosa and Carrica papaya were obtained from a private garden and Ricinus communis from around the university as an invasive plant [21][22][23][24][25][26][27][28][29]. All plant species were said to have proteinases and/ or nitrogenous compounds.…”
