目的 研究鸦胆子Brucea javanica种子的化学成分。方法 运用硅胶色谱、ODS、Sephadex LH-20等色谱方法进行分离纯化,结合高分辨质谱和核磁共振波谱分析鉴定化合物的结构。结果 从鸦胆子种子90%乙醇提取物中分离得到5个苦木内酯类化合物,分别鉴定为鸦胆子内酯W(1)、yadanziolide A(2)、鸦胆子苦素D(3)、鸦胆子苦素E(4)、javanicolideA(5)。结论 化合物1为未见文献报道的新化合物。

Objective To investigate the chemical constituents from Bruceae Fructus (the seeds of Brucea javanica). Methods These compounds were isolated by means of silica gel, ODS, Sephadex LH-20 column chromatographies. Their structures were identified by the methods of high resolution mass spectrometry (HRMS) and NMR spectroscopic analyses. Results Five quassinoids were isolated from 90% ethanol extract in Bruceae Fructus and identified as yadanziolide W (1), yadanziolide A (2), bruceine D (3), bruceine E (4), javanicolide A (5), respectively. Conclusion Compound 1 is a new quassinoid which has not been reported in literature.
