New Hydroxylated Spermidine Alkaloids from Pleurostylia opposita(WALL.) MERILL‐METCALF

Abstract
The leaves of a New Caledonian celastraceae, Pleurostylia opposita (WALL.) MERRILL‐METCALF, have yielded three new spermidine alkaloids, 7‐hydroxypleurostyline (1), 7‐hydroxycelacinnine (2), and 7′‐hydroxy‐7′,8′‐dihydropleurostyline (3), as minor basic constituents, together with three related alkaloids pleurostyline (4), celacinnine (5), and celallocinine (6).
