Objective To study the chemical constituents of Euphorbia helioscopia.Methods The compounds were isolated and purified by silica gel, SephadexLH-20 column chromatography and preparative HPLC, and their structures were identified by analysis of physicochemical properties and spectroscopic evidences. Results Twenty-three compounds were isolated from the 70% EtOH extract of E. helioscopia. Their structures were identified as β-sitosterol (1), euphoscopin B (2), 4-hydroxyacetophenone (3), euphoscopin F (4), euphoscopin C (5), nepehinol (6), 4-hydroxy-3,5-dimethoxybenzaldehyde (7), antiquorin (8), 1H-indole-3-carboxaldehyde (9), 7-hydroxy-6-methoxycoumarin (10), helioscopinolide A (11), euphoheliosnoid A (12), pinoresinol (13), (+)-dehydrovomifoliol (14), loliolide (15), 1-(4-hydroxy-3-methoxy-phenyl)-3-hydroxypropan-1-one (16), 3-(hydroxyacetyl) indole (17), aurantiamide (18), rayalinol (19), 3-O-β-D-glucopyranosylhelioscopinolide A (20), naringenin (21), 4',5,7- trihydroxyisoflavones (22) and quercetin (23). Conclusion Compounds 10, 17, 19, 20, 22 are isolated from Euphorbia genus for the first time, 3, 7-9,14-16, 18 are isolated from E. helioscopia for the first time.
