Visible-Light-Promoted Tandem Thiol-Ene Click Reaction/Transannular Cyclization and Regioselective Cyclopropane Ring-Opening to Construct Sulfur-Containing Euphorbia Diterpenes.

Organic Letters, 2023
The biorelevant sulfur-containing Euphorbia diterpenes with scarce 5/7/6/3 premyrsinane- and 5/7/6 myrsinane-type backbones were easily constructed from naturally abundant lathyrane-type Euphorbia factor L3 by visible-light-triggered tandem thiol-ene ...

The irritant toxins of Blue Euphorbia (Euphorbia coerulescens Haw.)

Toxicon, 1978
Euphorbia coerulescens (Fam. Euphorbiaceae) or Sweetnoors is indigenous to South Africa, where it is used as an animal feedstuff. Several more toxic species including E. franckiana, E. ledienii and E. cooperi, are indigenous to the same area. The relative toxicities of these latices were assessed by a mouse ear irritancy test. E.

Laticifers and the classification of Euphorbia: the chemotaxonomy of Euphorbia esula L.

Botanical Journal of the Linnean Society, 1987
Laticifers and the classification of Euphorbia: the chemotaxonomy of Euphorbia esula L. Articulated and non-articulated laticifer cells represent distinctive cell types of relatively recent origin and occur in only a few families. Both types are of separate phylogenetic origin, reflecting independent evolutionary trends in the Euphorbiaceae.
