PRISEs (progesterone 5β-reductase and/or iridoid synthase-like 1,4-enone reductases) are involved in cardenolide and iridoid biosynthesis. We here investigated a PRISE (rAtSt5βR) from Arabidopsis thaliana, a plant producing neither cardenolides nor ...

Iridoide, X: Stereospezifische Synthese von Iridoid‐α‐glucosiden
Chemische Berichte, 1978Iridoids, X: Stereospecific Synthesis of Iridoid‐α‐glucosidesTreatment of the iridoidaglycone 3 with 1,2‐anhydro‐α‐D‐glucopyranose triacetate (Brigls anhydride, 4) in the presence of a trace of boron trifluoride/ether led stereospecifically to the α‐glucosides 7, 8, and 9, with 38% yield. In an analogous reaction 10 was formed from 2.

Iridoids From Loasa Acerifolia
Phytochemistry, 1998In the course of preliminary chemotaxonomic studies on Loasaceae from South and Central America, 30 species from 6 genera were screened by chromatographic means. From the aerial parts of Loasa acerifolia Dombey, the novel trimeric and dimeric iridoid glucosides acerifolioside and tricoloroside methyl ester, consisting of loganin and secoxyloganin ...

Iridoids, iridoid-triterpenoid congeners and lignans from Desfontainia spinosa
Phytochemistry, 1986Abstract The leaves of Desfontainia spinosa ; were found to contain the three known seco-iridoids secoxyloganin, dimethyl secologanoside and sweroside in addition to the three iridoids loganin, loganetin and loganic acid previously reported. In addition a novel loganin derivative 7- O -( p -coumaroyl)-loganin was isolated. The leaves were also found
