Abstract
The phytochemistry of two Madagascan Crinum species, Crinum hardyi Lehmiller and Crinum pronkii Lehmiller were investigated and compared to that of Crinum firmifolium Baker which has been investigated previously. In addition to hippadine, lycorine, hippeastrine, masonine and crinine from C. firmifolium, lycorine, crinine, and 6-hydroxycrinamine from Crinum hardyi and lycorine, 6-hydroxycrinamine and pseudolycorine from C. pronkii, the novel lycorine-relatediminium salt, the 6,7,11b,11c-didehydrolycorinium salt, was isolated from bulbs of both C. firmifolium and C. hardyi.
