摘要
目的研究羽叶丁香Syringa pinnatifolia去皮的干燥根和枝干的化学成分。方法采用硅胶和Sephadex LH-20柱色谱法及HPLC进行分离,运用谱学分析鉴定所得化合物的结构。结果从山沉香乙醇提取物分离得到了3个木脂素类化合物,分别鉴定为3,3′,4-三甲氧基-4′,8,9,9′-四羟基简单木脂素(1)、3,3′,4,9-四甲氧基-4′,8-二羟基-9′-乙氧基简单木脂素(2)和3,3′,4,9-四甲氧基-4′,8,9′-三羟基简单木脂素(3)。结论化合物1～3为未见文献报道的新化合物,分别命名为山沉香木脂素C、山沉香木脂素D和山沉香木脂素E。
Objective To study the chemical constituents from the peeled dried roots and stems of Syringa pinnatifolia. Methods The chemical constituents from the peeled dried roots and stems of S. pinnatifolia were isolated and purified by silica gel and Sephadex LH-20 column chromatography, and preparative HPLC. The structures were identified by spectral methods. Results Three compounds were obtained and identified as lignan, namely 3, 3＇, 4-trimethoxy-4＇, 8, 9, 9＇-tetrahydroxy simple lignan （1）, 3, 3＇, 4, 9-tetramethoxy-4＇, 8-dihydroxy-9＇-ethoxy simple lignan （2）, and 3, 3＇, 4, 9-tetramethoxy-4＇, 8, 9＇-trihydroxy simple lignan （3）. Conclusion Compounds 1--3 are new, named syripinnalignan C, syripirmalignan D, and syripinnalignan E.
