    Five iridoidal glycocosides from Gentiana urnula.[Reference: WebLink]
    Five new iridoidal glycosides, gentiournoside A, gentiournoside B, gentiournoside C, Gentiournoside D, gentiournoside E were isolated from the whole herb of Gentiana urnula. Their structures were elucidated mainly by spectral methods. Among which gentiournoside A, gentiournoside B, gentiournoside C are bis-iridoidal glycosides while Gentiournoside D and gentiournoside E are loganin type ones. It is noted that all the glycosides possess a 2,3-dihydroxy benxoyl benxoyl unit or its derivative in the molecule.
