Seven alkaloids have been isolated fromL.clavatumLinn. collected in Jamaica, clavolonine C16H25NO2, fawcettiine C18H29NO3, base A (now named fawcettimine), lycopodine, dihydrolycopodine, and L.2 (acetyldihydrolycopodine). Fawcettimine is a secondary amine now shown to be C16H25NO2. The isolation of deacetylfawcettiine C16H27NO2in quantity from a later extraction indicated that there was a seasonal variation in the alkaloid content of the plant. These bases differ from those obtained fromL.clavatumof Canadian or European origin.
