目的 研究羽葉丁香Syringa pinnatifolia去皮的干燥根和枝干的化學成分。方法 采用硅膠和Sephadex LH-20柱色譜法及HPLC進行分離，運用譜學分析鑒定所得化合物的結構。結果 從山沉香乙醇提取物分離得到了3個木脂素類化合物，分別鑒定為3, 3′, 4-三甲氧基-4′, 8, 9, 9′-四羥基簡單木脂素（1）、3, 3′, 4, 9-四甲氧基-4′, 8-二羥基-9′-乙氧基簡單木脂素（2）和3, 3′, 4, 9-四甲氧基-4′, 8, 9′-三羥基簡單木脂素（3）。結論 化合物1～3為未見文獻報道的新化合物，分別命名為山沉香木脂素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, syripinnalignan D, and syripinnalignan E.
