In this study, three tetracyclic triterpenes: (3S,24S)-tirucall-7-ene-3,24,25-triol (1), (3S,24R)-tirucall-7-ene-3,24,25-triol (2) and inoterpene C (3), were isolated from the milkweed Euphorbia nicaeensis All. using dry-column flash silica gel chromatography and semipreparative normal-phase HPLC. Their structures were determined on the basis of 1D and 2D NMR spectra and literature review. Although these three compounds have previously been isolated from other plant species, this is the first time that they have been isolated from E. nicaeensis.
U ovom radu, tri tetraciklična triterpena: (3S,24S)-tirukal-7-en-3,24,25-triol (1), (3S,24R)-tirukal-7-en-3,24,25-triol (2) i inoterpen C (3) su izolovana iz mlečike Euphorbia nicaeensis All. koristeći brzu hromatografiju na suvom stubu silika gela i semipreparativnu normalno-faznu HPLC. Strukture su određene na osnovu 1D i 2D NMR spektara i poređenjem sa literaturom. Iako su ova tri jedinjenja ranije izolovana iz drugih biljnih vrsta, ovo je prvi put da su izolovana iz E. nicaeensis.
