Iridoids of Rauwolfia grandiflora☆
Phytochemistry, 1994Abstract From the bark of Rauwolfia grandiflora a new monoterpenoid δ-lactone, isoboonein, was isolated together with boonein, loganin and loganic acid. The structure of isoboonein, established by spectroscopical methods, was confirmed by partial synthesis from loganic acid.

Iridoids from Mentzelia cordifolia
Phytochemistry, 1995Abstract From the aerial parts of Mentzelia cordifolia , 11 known compounds, seven phenolics and four iridoids have been identified. In addition, two new iridoids, i.e. mentzefoliol and glucosylmentzefoliol, have been isolated and characterized. Their structures have been elucidated mainly by means of spectroscopic data.

Biosynthesis of iridoids in Syringa and Fraxinus: Carbocyclic iridoid precursors
Phytochemistry, 1995Feeding experiments with deuterium-labelled precursors to Fraxinus excelsior, Syringa josikaea and S. vulgaris have shown that the biosynthesis of the oleoside-type secoiridoids (e.g. oleuropein) proceeds via iridodial, iridotrial, deoxy-loganic acid aglucon and deoxy-loganic acid.

Iridoids and seco-iridoids from the leaves of Cephalanthus glabratus (Spreng.) K.Schum
Brazilian Journal of Botany, 2020In this work, the first phytochemical analysis on Cephalanthus glabratus (Spreng.) K.Schum. regarding its composition in iridoids was reported. The analysis was carried out by following current usual methodologies in the extraction, separation and identification procedures.
