Research progress on metabolism and pharmacological activities of several iridoid glycosides

Abstract

As a large category of natural products widely present in traditional Chinese medicine, iridoid glycosides have multiple pharmacological activities. Recent researches suggest that iridoid glycosides mainly exist in vivo in the forms of original form, aglycone and a series of their Ⅰ and Ⅱ metabolites under the biotransformation effect, and their metabolites have been proved to have multiple pharmacological activities. The research progress on in vivo metabolism and metabolite activities of several iridoid glycosides would be reviewed in this article, to provide a theoretical basis for the further development and utilization of iridoid compounds and their metabolites.
