Clerodane diterpenoids from Salvia splendens.
2006
Four new clerodane diterpenoids, salvisplendins A-D (1-4), have been isolated from an acetone extract of the flowers of SalVia splendens, together with an artifact (5), arising from salvisplendin D (4) by addition of diazomethane, and the already known clerodane olearin (6). The structures of the new compounds (1-5) were established mainly by 1D and 2D NMR spectroscopic studies and, in the case of salvisplendin A (1), by chemical correlation with splenolide B (7). Complete 1H and 13C NMR assignments for olearin (6), not published hitherto, are also reported.

The diterpenoids from the genus Sideritis
2006
ABSTRACT: The genus Sideritis consists of 100-150 or more species, growing mainly in the countries around the Mediterranean area. The genus is particularly rich in diterpenoids, occurring in almost all the species, and shows many different carbon skeleta. Several species are still used in traditional medicine. Recent studies indicated the occurrence of interesting biological activities, like anti-inflammatory, antibacterial, antimicrobial, anti-HIV replication, antifeedant, antiulcerogenic, analgesic, and antihypoglycaemic.
Crystal structure, Hirshfeld surface analysis and electrostatic potential study of naturally occurring cassane-type diterpenoid Pulcherrimin C monohy…
2019
Single crystal X-ray diffraction analysis and Hirshfeld surface analysis of the title compound were carried out to analyse quantitatively the intermolecular interactions involved in the crystal packing. The electrostatic potential surface was generated over the Hirshfeld surface to visualize the potential active sites.
