| Abstract: | 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. |
