ABSTRACT

Toxic Principle and Mechanism of Action Although the specific toxins have not been identified, Haemanthus species contain phenanthridine alkaloids including lycorine, coccinine, montanine, hippeastrine, and haemanthidine.1 The phenanthridine alkaloids are present in many of the Liliaceae, most notably in the Narcissus group. The bulbs appear to be the most toxic.2
