Iridoid Glucosides from the Fruit of Genipa americana

Abstract

Four new iridoid glucosides, called genamesides A—D, have been isolated from the fruit of Genipa americana L. (Rubiaceae), along with four known iridoid glucosides, geniposidic acid, geniposide, gardenoside and genipin-gentiobioside. Their chemical structures were determined on the basis of spectroscopic data.
