Iridoid glycosides from the flowering plant Lamourouxia dasyantha (Cham. & Schltdl.) W.R. Ernst

Three iridoid glycosides (mussaenoside, geniposide, and 5-hydroxy-8-epi-deoxyloganin) along with mannitol and acteoside, were isolated from Lamourouxia dasyantha, an endemic plant species of Mexico that currently belongs to the Orobanchaceae family. There is no information about the chemical composition of this species, consequently, the present work focuses on the chemical study of the flowers and leaves of L. dasyantha, which were collected in two batches in Mexico, identifying the main components of each batch. The chemical structures were completely established by spectroscopic methods. Since the present contribution is the first report about the chemical composition of the species L. dasyantha, would be useful in the taxonomic area but also in the clinical due to the wide spectrum of pharmacological activities of the iridoid glycosides reported, principally anti-inflammatory properties with novel mechanisms of action.
