Two newindolizidinealkaloids, (±)‐3‐oxoisoelaeocarpine (1) and (±)‐elaeocarpine N‐oxide (2), along with three known alkaloids, (±)‐isoelaeocarpine (3), (±)‐elaeocarpine (4), and (−)‐isoelaeocarpiline (5), were isolated from an EtOH extract of the branches and leaves of Elaeocarpus sphaericus. The structures of these compounds were determined by spectroscopic and chemical methods. Furthermore, enantiomers
