Eleven alkaloids have been isolated from whole plants of Narcissus bujei (Amaryllidaceae). The alkaloids 11-O-acetylhaemanthamine and bujeine are reported for the first time. The structure and stereochemistry of these new alkaloids have been determined by physical and spectroscopic methods. The X-ray diffraction analysis of O-methyllycorenine hydrochloride has been performed. (C) 1998 Elsevier Science Ltd. All rights reserved.
