摘要：

The nature of the iridoid glucosides and verbascosides in Retzia capensis has been investigated. The known iridoids unedoside, stilbericoside, thunbergioside and adoxosidic acid were isolated in addition to the partly characterized retzioside and three other new iridoids with an eight carbon aglucone. Two of these, namely holmioside and 5-deoxythunbergioside, have been fully characterized. The third new iridoid, 5-deoxyholmioside, was present in small quantities and only characterized by NMR. Three verbascosides were found, namely verbascoside, calceolarioside E, and a compound which was tentatively identified as calceolarioside E with an apiosyl residue attached to the 6-position of the glucopyranosyl moiety.
