Euphorbia species were widely used in traditional medicines for the treatment of several diseases. From the aerial parts of Egyptian endemic plant, Euphorbia sanctae-catharinae , three new premyrsinane diterpenoids, namely, euphosantianane E-G ( 1 - 3 ), alongside four known triterpenes, 9,19-cyclolanostane-3β,24 S -diol ( 4 ), 25-methoxycycloartane-3β,24 S -diol ( 5 ), 25-methylenecycloartan-3β,24 R -diol ( 6 ), and 25-methylenecycloartan-3β,24 S -diol ( 7 ), were isolated and identified. The chemical structures were proven depending upon spectroscopic analysis, including FTIR, HRFABMS, and 1D/2D-NMR. The chemotaxonomic significance of the isolated compounds, especially diterpenes from E. sanctae-catharinae compared to those documented from different Euphorbia species was also studied via agglomerative hierarchical clustering (AHC). The Egyptian endemic Euphorbia sanctae-catharina was grouped with E. bupleuroides , E. fidjiana , E. fischeriana , E. pithyusa subsp. cupanii , E. prolifera , and E. seguieriana , where myrsinol diterpenoids were the characteristic compounds.
