目的研究狼毒大戟乙酸乙酯部位的化学成分。方法采用硅胶柱色谱法和高效液相色谱法进行分离纯化,通过波谱分析鉴定化合物的结构。结果鉴定了14个化合物,分别为2,4-二羟基-6-甲氧基-3-甲基苯乙酮(1),12-脱氧佛波醇-13-十六酸酯(2),没食子酸乙酯(3),七叶壳(4),2,4-二羟基-6-甲氧基苯乙酮(5),12-脱氧佛波醇-13-乙酸酯(6),12-脱氧佛波醇-13,20-二乙酸酯(7),jolkinetin B(8),17-羟基jolkinetin B(9),17-羟基-jolkinetrin A(10),langduin C(11),3-甲基对羟基苯甲酸(12),没食子酸甲酯(13),3,3 ′-二乙酰基-吡啶-4,4 ′-二甲氧基-2,2 ′,6,6 ′-四羟基二苯甲烷(14)。结论化合物3、5、12、13为首次从该植物中分离得到。
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.
