摘要
通过硅胶、大孔树脂、葡聚糖凝胶Sephadex LH-20和HPLC等多种色谱分离方法相结合,从慈竹茹Sinocalamusafinis茎的乙醇提取物的乙酸乙酯萃取部分中分离得到15个化合物;借助理化性质和波谱学数据分析,鉴定其结构为(+)-(1S,2R)-1,2-双(4-羟基-3-甲氧基苯基)-1,3-丙二醇(1),苏式-愈创木基甘油-β-O-4'-松柏基醚(2),赤式-愈创木基甘油-β-O-4'-松柏基醚(3),(+)-(7S,8R,8'R)-5'-甲氧基落叶松树脂醇(4),(+)-(7S,8R,8'R)-5,5'-二甲氧基落叶松树脂醇(5),(±)-秃毛冬青素Ⅰ(6),(-)-丁香树脂酚(7),(-)-杜仲树脂酚(8),(-)-(8R,8R')-4,4'-二羟基-3,3',5,5'-四甲氧基木脂烷-9,9'-二醇(9),(-)-开环异落叶松树脂酚-9,9'-缩丙酮(10),(+)-珍珠花树环木脂醇(11),2,6-二甲氧基吡喃-4-酮(12),β-谷甾醇(13),4-羟基桂皮酸(14)和2,6-二甲氧基对苯醌(15)。这些化合物均为首次从慈竹属植物中分离得到,其中化合物12为新天然产物。
Fifteen compounds were isolated from the stem(with skin removed) of Sinocalamus affinis by a combination of vari- ous chromatographic techniques including silica gel, macroporous adsorbent resin, Sephadex LH-20, and preparative HPLC. Their structures were elucidated by spectroscopic data as ( + ) -( 1 S, 2R) -1, 2-bis ( 4-hydroxy- 3-methoxyphenyl) -1, 3-propanediol ( 1 ) , threo-guaiacylglycerol-β-O-4'-coniferyl ether( 2 ), erythro-guaiacylglycerol-β-O-4'-coniferyl ether ( 3 ), ( + ) -( 7S, 8R, 8' R ) -5'-me- thoxylariciresinol (4) , ( + ) - ( 7S, 8R, 8' R ) -5, 5 '-dimethoxylariciresinol ( 5 ) , ( ± ) -glaberide Ⅰ ( 6 ) , ( - ) -syringaresinol ( 7 ) , ( - ) -medioresinol(8) , ( - ) - (8R, 8R') -4, 4'-dihydroxy-3, 3', 5, 5'-tetramethoxyligna-9, 9'-diol (9) , ( - ) -secoisolariciresinol- 9, 9'-acetonide ( 10 ), and ( + ) -lyoniresinol ( 11 ) ; a new natural product 2, 6-dimethoxypyran-4-one ( 12 ), and fl-sitosterol, 4-hydroxycinnamic acid, and 2, 6-dimethoxy-p-benzoquinone. These compounds were isolated from the genus Sinocalamus for the first time, compound 10 should be an artifact.
