Abstract
Six new terpenoids (1–6) and two new phloroglucinol glucosides (7 and 8) were isolated from the extract of Syzygium szemaoense leaves. Among the isolates, compounds 1 and 2 (named syzygiumursanolides A and B) were unusual 28-norursane type triterpenoids with 19(18→17)-abeo spirocyclic skeleton. And syzygiumone B (8) was rare ascorbyl-modified phloroglucinol glucoside. Their structures were elucidated on the basis of comprehensive 1D and 2D NMR,...
