Cl. Zani et al., CHEMISTRY OF BRAZILIAN EUPHORBIACEAE .1. MOLLUSCICIDAL MILLIAMINES FROM EUPHORBIA-MILII VAR HISLOPII, Phytochemistry, 34(1), 1993, pp. 89-95
From the latex of Euphorbia milii var. hislopii collected in Brazil, e
ight milliamines were isolated using a bioassay-guided protocol based
on molluscicidal activity. Three were known milliamines A, D and E, th
e other five being new compounds of this class. Milliamine L, a dianth
raniloyl peptide ester of ingenol, was found to be molluscicidal at 4
nM (2.5 mug l-1).
