从 Teclea nobilis 的地上部分分离出五种新的呋喃喹啉生物碱，即 tecleabine (1)、tecleoxine (2)、isotecleoxine (3)、methylnkolbisine (4) 和 clodesnkolbisine (5)，以及七种已知的呋喃喹啉衍生物；一种吖啶酮生物碱。和一种已知的黄烷酮。通过一维和二维核磁共振波谱数据，包括COSY、HMQC和HMBC实验以及HRMS，建立了生物碱1-5的结构。 (C) 2003 Elsevier Ltd. 保留所有权利。
Five new furoquinoline alkaloids, namely tecleabine (1), tecleoxine (2), isotecleoxine (3), methylnkolbisine (4) and chlorodesnkolbisine (5) were isolated from the aerial parts of Teclea nobilis, together with seven known furoquinoline derivatives; one acridone alkaloid. and one known flavanone. The structures of the alkaloids 1-5 were established by 1D and 2D NMR spectral data, including COSY, HMQC and HMBC experiments, as well as HRMS. (C) 2003 Elsevier Ltd. All rights reserved.
