Three new C6–C2 natural alcohols, rengyol (1), rengyoxide (2), and rengyolone (3), have been isolated from Forsythiasuspensa fruits, along with a novel glycoside, forsythoside E (4), a new sugar ester, 4-caffeoylrutinose, and a known quinol glucoside, cornoside (5). Chemical and spectroscopic studies have established the structures of these new constituents.
