Objective To study the chemical constituents of Euphorbia stracheyi Boiss.Methods The chemical constituents were isolated and purified by various chromatographic techniques.Their structures were determined on the basis of physical properties and spectroscopic data.Results Fifteen compounds were isolated and elucidated as n-octacosanol(1),1-heptadecanoyl glycerol(2),hexacosanol(3),β-sitosterol(4),β-daucosterol(5),1-octadecanol(6),stigmasterol(7),apigenin(8),gallic acid(9),orientin(10),quercetin-4′-O-D-galactoside(11),mannitol(12),sucrose(13),quercetin-4′-O-β-glucopyranoside(14) and luteolin-5-O-β-D-glucoside(15).Conclusion All compounds were isolated from this plant for the first time.
