Acetone extract of aerial parts of Euphorbia marschalliana collected from Iran has been subjected to different chromatography techniques for fractionation and purification. The stereo- structures of the myrsinol esters 15-O-acetyl-3-O-propionyl-5-O-butanoyl-7-O-nicotinoylmyrsinol (1) and 15-O-acetyl-3,5-O-dibutanoyl-7-O-nicotinoylmyrsinol (2) have been probed using ROESY spectroscopy and modified for the stereochemistry at C-6, C-12 and C-13. β-Sitosterol (3), 29-norcycloart-5-ene (4), 5,8-lanostadiene-3β-ol (5), 3β,24(S),25-trihydroxycycloartane (6), 3β,24(R),25-trihydroxycycloartane (7) and 24-methylenecycloartan-3β-ol (8) were identified for the first time in this plant.
