Three new erythrina alkaloids, eryalkals A (), B (), and C (), were isolated from the roots of L. Their structures, including their absolute configurations, were elucidated based on analyses of HR-ESI-MS, 1D/2D NMR and single-crystal X-ray diffraction techniques. The isolated erythrina alkaloids were screened for the antioxidant and cytotoxic activities. All the compounds showed no antioxidant activity and cytotoxic activities.
从 L. 的根部分离得到三种新的木豆碱生物碱，eryalkals A ()、B () 和 C ()。基于高分辨电喷雾电离质谱（HR-ESI-MS）、1D/2D NMR 和单晶 X 射线衍射技术的分析，确定了它们的结构，包括绝对构型。对分离得到的木豆碱生物碱进行了抗氧化和细胞毒性活性筛选。所有化合物均无抗氧化活性和细胞毒性。
