Abietane diterpenoids from Salvia microstegia

open access: yesPhytochemistry, 1991
Abstract Four abietane diterpenoids were isolated from the aerial parts of Salvia microstegia . Two, ferruginol and pisiferal, are known compounds. The other two, 10-acetylferruginol and 5,11,12-trihydroxy-abieta-8,11,13-triene, are new compounds.

A two‐photon fluorescence micro‐spectroscopy method for chemotaxonomic characterization of fossil resins

open access: yesApplications in Plant Sciences, Volume 14, Issue 2, March-April 2026.
Abstract Premise Amber, a fossilized chemical defensive exudate, is important for understanding ancient plant–insect/pathogen interactions, yet its botanical origins, especially for Cretaceous amber, remain enigmatic. Here, we develop and apply a fluorescence micro‐spectroscopy approach within the context of a larger study on the provenance of amber ...
