Iridoids and seco-iridoids from the leaves of Cephalanthus glabratus (Spreng.) K.Schum

In this work, the first phytochemical analysis on Cephalanthus glabratus (Spreng.) K.Schum. regarding its composition in iridoids was reported. The analysis was carried out by following current usual methodologies in the extraction, separation and identification procedures. Four compounds were isolated, i.e., the iridoid loganin (1) and the seco-iridoids sweroside (2), secologanin (3) and secoxyloganin (4). Their presence allowed to provide important confirmations about the chemotaxonomy of the genus and the family this species belongs to.
