[Study on the chemical constituents from fresh roots of Euphorbia fischeriana].
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).


CONCLUSIONS
Compounds 3, 5, 12, 13 are isolated from this plant for the first time.
