LYCOPODIUM ALKALOIDS: PART IV. ALKALOIDS OF JAMAICAN LYCOPODIUM CLAVATUM LINN.

Abstract

Seven alkaloids have been isolated from L. clavatum Linn. collected in Jamaica, clavolonine C 16 H 25 NO 2 , fawcettiine C 18 H 29 NO 3 , base A (now named fawcettimine), lycopodine, dihydrolycopodine, and L.2 (acetyldihydrolycopodine). Fawcettimine is a secondary amine now shown to be C 16 H 25 NO 2 . The isolation of deacetylfawcettiine C 16 H 27 NO 2 in 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 from L. clavatum of Canadian or European origin.
