OBJECTIVE To study the chemical constituents in ethyl acetate fraction from the Euphorbia fischeriana. METHODS The compounds were isolated by silica gel column chromatography and HPLC, and their structures were elucidated by means of spectral analyses. RESULTS Fourteen compounds were identified as 2,4-dihydroxy-6-methoxy-3-methylacetophenone (1), 12-deoxyphorbol-13-hexadecanoate (2), ethylgallate (3), esculetin (4), 2,4-dihydroxy-6-methoxy-acetophenone (5), 12-deoxyphorbol-13-acetate (6), 12-deoxyphorbol-13,20-diacetete (7), jolkinolide B (8), 17-hydroxyjolkinolide B (9), 17-hydroxy-jolkinolide A (10), langduin C (11), 3-methylp-hydroxybenzoic acid (12), methyl gallate (13), 3, 3'-diacetyl-pyridine-4,4'-dimethoxy-2, 2', 6, 6'-tetrahydroxydiphenylmethane (14). CONCLUSION Compounds 3, 5, 12, 13 are isolated from this plant for the first time.
