Sesquiterpene lactone in Tapinanthus dodoneifolius (Dancer) DC: A phytochemistry according parasite’s host

Abstract

Loranthaceae are parasitic plants used in traditional medicine. Their use generally depends on the host plant. This shows that the biological properties of these species depend on their host. As phytochemistry is responsible for biological properties, it depends on the parasite's host. The aim of this study was to evaluate the variation in phytochemistry and antioxidant activity of Tapinanthus dodoneifolius leaves and bark harvested from different hosts using IR, UV and TLC methods. The results showed that the total polyphenol content of T. dodoneifolius twig bark harvested from Acacia seyal, Albizia lebbeck and Piliostigma reticulatum was identical. The same observation is made with the leaves, the content of which remains lower than that twigs barks. Leaves contain more total flavonoids than twig bark. Infrared, UV and TLC analyzes showed the presence of sesquiterpene lactones in leaves extracts of T. dodoneifolius harvested from A. lebbeck and P. reticulatum. The best antioxidant activity was obtained with the bark of T. dodoneifolius harvested from A. lebbeck and P. reticulatum.
