摘要:

对油樟叶水提物的化学成分进行研究,采用大孔吸附树脂、PRP-512A树脂和Sephadex LH-20等色谱分离技术分离纯化得到24个化合物,利用UV、MS和NMR等波谱学手段对化合物结构进行鉴定。研究结果表明24个化合物分别为:6-甲氧基-7-羟基香豆素(1)、异嗪皮啶(2)、甲基牛蒡酚(3)、(+)-表芝麻酮(4)、(7R, 7'S, 8R, 8'R)-3, 4-亚甲二氧基-3'-甲氧基-4'-羟基-7, 9': 7', 9-双环氧木脂烷(5)、(+)-表松脂醇(6)、(+)-松脂醇(7)、(+)-松脂素单甲基醚(8)、(+)-O-去甲基木兰木脂素(9)、连翘脂素(10)、(2R, 3S)-4'-羟基-5, 7, 3'-三甲氧基黄烷-3-醇(11)、(2S, 3S)-4'-羟基-5, 7, 3'-三甲氧基黄烷-3-醇(12)、槲皮素(13)、黑麦草内酯(14)、2, 6-二甲氧基对苯醌(15)、邻苯二酚(16)、香草酸(17)、3-甲氧基-4-羟基苯乙醇(18)、二氢松柏醇(19)、3, 5-二甲氧基- 4-羟基苯丙醇(20)、2-羟基-1-(4-羟基-3, 5-二甲氧基苯基)-1-丙酮(21)、丁香酸甲酯(22)、1-(4-乙基苯基)-1, 2-乙二醇(23)和对羟基苯乙酮(24)。化合物25~69~1214~1618~24这17个化合物均为首次从樟属植物中分离得到。抗肝癌活性结果显示:化合物2513对人肝癌细胞HepG2具有中等抑制活性,半数抑制浓度(IC50)分别为33.43、107.40和71.43 μmol/L,其中化合物5的抗肝癌活性为首次报道,化合物213分属香豆素类和黄酮类化合物,在抗肿瘤药物研究方面具有良好应用前景。

Abstract:

This chemical constituents of the aqueous extract of leaves of Cinnamomum longepaniculatum(Gamble) N. Chao ex H.W.Li were studied. Twenty-four compounds were isolated and purified by macroporous resin, PRP-512A resin, Sephadex LH-20, and etc. The structures of the compounds were identified by spectroscopic methods of UV, MS and NMR as 7-hydroxy-6-methoxy-coumarin(1), isofraxidin(2), dimethylmatairesinol(3), (+)-episesaminone(4), horsfieldin(5), (+)-epipinoresinol(6), (+)-pinoresinol(7), (+)-pinoresinol monomethyl ether(8), (+)-de-O-methylmagnolin(9), phillyrin(10), (2R, 3S)-4'-hydroxy-5, 7, 3'-trimethoxyflavan-3-ol(11), (2S, 3S)-4'-hydroxy-5, 7, 3'-trimethoxyflavan-3-ol(12), quercetin(13), loliolide(14), 2, 6-dimethoxy-1, 4-benzoquinone(15), pyrocatechol(16), vanillic acid(17), 3-methoxy-4-hydroxyphenylethanol(18), dihydroconifery alcohol(19), 3, 5-dimethoxy-4-hedroxyphenylpropynol(20), 2-hydroxy-1-(4-hydroxy-3, 5-dimethoxyphenyl)propan-1-one(21), methyl syringate(22), 1-(4-ethylphenyl)-1, 2-ethanediol(23), p-hydroxyacetophenone(24). Compounds 2, 5-6, 9-12, 14-16 and 18-24 were all isolated from Cinnamomum for the first time. The results of anti-hepatocellular-activity showed that compounds 2, 5 and 13 had moderate inhibitory activity effects on human liver cancer(HepG2) cells, with the half inhibitory concentrations(IC50) values of 33.43, 107.40, and 71.43 μmol/L, respectively. Among them, the anti-hepatocellular-activity of compound 5 was reported for the first time. Compounds 2 and 13 belong to coumarins and flavonoids, which have good application prospects in the research of anti-tumor drugs.
