摘要
研究大风子科大风子属植物大风子Hydnocarpus anthelminthica中的木脂素类成分。采用聚酰胺柱色谱、反相硅胶柱色谱、Sephadex LH-20凝胶柱色谱以及制备型HPLC等色谱技术对大风子的95%乙醇提取物进行分离纯化,通过波谱学方法(MS,NMR)进行结构鉴定。从大风子的95%乙醇提取物中分离并鉴定了13个木脂素类化合物,分别为(+)-丁香脂素(1),lirioresinol A(2),(+)-medioresinol(3),(7R,8R,8′R)-4′-guaiacylglyceryl-evofolin B(4), leptolepiso C(5),(-)-(7R,7′R,7″R,8S,8′S,8″S)-4′,4″-dihydroxy-3,3′,3″,5,5′,5″-hexamethoxy-7,9′:7′,9-diepoxy-4,8″-oxy-8,8′-sesquineolignan-7″,9″-diol(6),(-)-(7R,7′R,7″R,8S,8′S,8″S)-4′,4″-dihydroxy-3,3′,3″,5,5′-pentamethoxy-7,9′:7′,9-diepoxy-4,8″-oxy-8,8′ses-quineolignan-7″,9″-diol(7),肥牛木素(8),dydnocarpusol(9),isohydnocarpin(10),(-)-hydnocarpin (11),hydnocarpin (12),hydnocarpin-D(13)。其中,化合物1～8为首次从该属植物中分离得到。
This project is to investigate lignans from the seed of Hydnocarpus anthelminthica. Thirteen lignans were isolated from the 95% ethanol extract of the seed of H. anthelminthica, by polyamide resin, Sephadex LH-20, ODS column chromatography and preparative HPLC. Their structures were elucidated as(+)-syringaresinol(1), lirioresinol A(2),(+)-medioresinol(3),(7R,8R,8′R)-4′-guaiacylglyceryl-evofolin B(4), leptolepisol C(5),(-)-(7R,7′R,7″R,8S,8′S,8″S)-4′,4″-dihydroxy-3,3′,3″,5,5′,5″-hexamethoxy-7,9′:7′,9-diepoxy-4,8″-oxy-8,8′-sesquineolignan-7″,9″-diol(6),(-)-(7R,7′R,7″R,8S,8′S,8″S)-4′,4″-dihydroxy-3,3′,3″,5,5′-pentamethoxy-7,9′:7′,9-diepoxy-4,8″-oxy-8,8′ses-quineolignan-7″,9″-diol(7), ceplignan(8), hydnocarpusol(9), isohydnocarpin(10),(-)-hydnocarpin(11), hydnocarpin(12), and hydnocarpin-D(13) by spectroscopic data analysis. Compounds 1-8 were obtained from the genus Hydnocarpus for the first time.
