✦ Synopsis

The structures of complex alkaloids of Celastraceae family have recently been elucidated (e g I evonlne) 1,2,3 In our continuing studies on alkaloldal components of Celastraceae family we have Isolated several alkaloids from Euonymus alatus forma striatus (thunb ) Maklno (Japanese name, Komayuml) evonlne L, 2,3 2 4 euonymlne, wllfordlne 2, and a new alkaloid alatamine 6_, ' mp 185-193' (MeOH), C41H45N018, [aliz + 44" (c 1 08 CHC13), UV (EtOH) 233 (E 24,400), 272 nm (5,300), -1 IR (CHC13) 3540, 1750 (broad), 1603, 1588, 1576 cm , mass 839 (M*), NMR (Table) I Relationship of wllfordlne 5 and alatamine 6_ Wllfordlne Lwas first Isolated In 1950, and some structural studies were performed by Acree and Haller, 6 and Beroza, 7,8 which are summarized below
