摘　　要：从多裂碎米荠(Cardamine multijuga)内生真菌隐孢丛赤壳菌Cryphonectria radicalis C2的代谢产物中分离得到两个化合物,经NMR、MS等现代谱学方法分别鉴定为蒽茜素(skyrin)(1)和大黄素(emodin)(2).活性测定结果表明,两个化合物对秀丽隐杆线虫没有杀虫活性.但蒽茜素对小麦根腐病菌禾旋孢腔菌和稻恶苗藤仓赤霉菌具有良好的抗真菌活性,而大黄素对禾旋孢腔菌、藤仓赤霉菌和魔芋镰刀菌等7株植物病原菌均具有良好的抗菌效果.Two compounds were isolated from the endophytic fungus Cryphonectria radicalis, which was iso- lated from Cardamine multijuga. Their structures were elucidated on the basis of spectral data. Compound 1 were identified as skyrin and 2 were emodin. Nematicidal activity test indicated that skyrin and emodin have no nematicidal activity against Caenorhdbditis elegans. However, skyrin showed antifungal activities against Cochliobolus sativus and Gibberellafujikuroi, and emodin showed antifungal activities against all 7 tested pathogenic fungi.
