Abstract
From the leaves of Elaeocarpus sphaericus (Gaertn.) K. Schum., seven
isomeric alkaloids of molecular formula, C16H21NO2,
have been isolated. Two of the alkaloids are identical with (-)-isoelaeocarpiline and (+)- elaeocarpiline previously
isolated from E. dolichostylis. Complete structures
and absolute configurations have now been determined for the two previously
known alkaloids (1) and (6), and for the five new- alkaloids (4), (8), (10),
(11), and (12), and a study has been made of the products obtained by sodium
borohydride reduction of some of the isomeric alkaloids. The previously known Elaeocarpus alkaloids, elaeocarpidine, (�)-elaeo-carpine, and (�)-isoelaeocarpine have also been
isolated from E. sphaericus.
