Three compounds, 20-O-acetyl-[3-O-(2'E,4'Z)-decadienoyl]-ingenol (1), 20-O-acetyl-[5-O-(2'E,4'Z)-decadienoyl]-ingenol (2) and 3-O-(2'E,4'Z)-decadienoylingenol (3), were isolated from Euphorbia kansui under the bioassay-guided method. Each compound showed the same antinematodal activity against the nematode, Bursaphelenchus xylophilus, at a minimum effective dose (MED) of 5 microg/cotton ball.

The mortality caused to the snail Bulinus wrighti (The snail vector of urinary schistosomiasis) by different extracts of two species of plants belonging to the family Euphorbiaceae has been investigated. It was found that very low concentrations of fresh leaf extracts were effective in killing the snail. The LC50 of methanol and acetone extracts for Euphorbia schimperiana and Euphorbia heliosco...

In the family of Euphorbiaceae, the genera Euphorbia and Sapium are known to contain essentially latex-bearing species. In the present study, the latex of Euphorbia selloi (Klotzsch & Garcke) Boiss., Euphorbia papillosa A.St.-Hil., and Sapium glandulosum (L.) Morong, plants native from Brazil, were examined concerning proteolytic activity. All studied species have proteins with significant prot...

Ten myrsinol diterpenes, euphorbiaproliferins A-J (1-10), along with nine known analogues (11-19) were isolated from the roots of Euphorbia prolifera. Their structures were elucidated by spectroscopic data analysis (IR, ESIMS, HRESIMS, 1D and 2D NMR), and the structure of 1 was confirmed by X-ray crystallography. The diterpenes showed neuroprotective effects against MPP+-induced neuronal cell d...
