Isolation of a new lipoxygenase active saponin and a new triterpenoid from the leaves of Trachelospermum lucidum

Abstract

A new saponin trivially named leucioside (1) and a new triterpenoid along with two known lignans trachelosiaside (3) and matairesionol (4) C-glycosides, were isolated from the butanolic fraction of Trachelospermum lucidum. Compounds 1 and 4 showed potent inhibitory activity against lipoxygenase while compounds 2 and 3 showed moderate activity against lipoxygenase. © 2005 Verlag der Zeitschrift für Naturforschung.
