| 中文摘要: |
| 利用正反相硅胶柱色谱和 Sephadex LH-20 凝胶柱色谱等分离技术对狼毒大戟
(Euphorbia fischeriana Steud)全株进行化学成分研究,利用NMR波谱技术和文献对照鉴定其结构,
从中分离鉴定了16个化合物,分别为(-)-3,3'-二去甲基松脂醇(1)、7-表-芝麻素-二儿茶酚(2)、
丁香脂素(3)、(+)-落叶松树脂醇-9-二十烷酸(4)、isoamericanin A (5)、N-苯甲酰基-L-苯丙氨酰-N-
苯甲酰基-L-苯丙氨酸酯(6)、(22E)-麦角甾-6,9,22-三烯-3β,5β,8α-三醇(7)、(22E,24R)-5α,
8α-表二氧-23-甲基麦角甾-6,22-二烯-3β-醇(9)、β-谷甾醇(10)、Schleicheol 1(11)、3'-(4''-羟基
-3''-甲氧基苯基)-苯甲酸丙酯(12)、3-羟基苯乙醇(13)、N-苯甲酰基-L-苯丙氨醇(14)、crypticin
B (15)、没食子酸(16)。化合物1、2、4‒7、9和12首次从大戟属植物中分离得到,除化合物10和16
外,其余化合物均首次从该植物中分离得到。化合物4显示出明显的乳腺癌细胞株(MCF-7)抑制
活性,IC50 = (11.3 ± 0.34)µmol/L[顺铂 IC50 = (6.2 ± 0.20)µmol/L]。 |
| 英文摘要: |
| Various separation techniques including normal and adverse silica gel and Sephadex LH-20 gel column chram‐
atography were used to investigate the chemical constituents from Euphorbia fischeriana Steud. Finally, sixteen compounds,
including (-)-3,3′-bisdemethylpinoresinol (1), 7-epi-sesamin- dicatechol (2), syringaresinol (3), (+)-lariciresinol-9-eico‐
sanoic acid (4), isoamericanin A (5), N-benzoyl-L-phenylalaninyl-N-benzoyl-L-phenylalaninate (6), (22E)-ergosta-6,9,
22-triene-3β,5β,8α-tiol (7), (22E,24R)-5α,8α-epidioxyergosta-6,22-diene-3β-ol (8), (22E,24R)-5α,8α-epidioxy-23-
methylergosta- 6,22- diene-3β-ol (9), β-sitosterol(10), Schleicheol 1 (11), 3′-(4′′-hydroxy-3′′-methoxyphenyl)-propyl
benzoate (12), 3-hydroxybenzene ethanol (13), N-benzoyl-L-phenyla-laninol (14), crypticin B (15), gallic acid (16) were
isolated, and their structures were identified by NMR data and comparison with values reported. Compounds 1, 2, 4‒7, 9,
and 12 were isolated from the genus Euphorbia for the first time. Except for 10 and 16, the others were firstly isolated from
E. fischeriana Steud. Compound 4 showed obvious inhibitory activity against breast cancer cell line (MCF-7) with IC50 of
(11.3 ± 0.34) μmol/L [cisplatin IC50 = (6.2 ± 0.20) μmol/L]. |
