Abstract The essential oil from fruits of Phellodendron chinense C. K. Schneid. was analyzed by GC, GC/MS and 1H-NMR spectroscopy. More than 90 compounds were identified. Myrcene (80.1â85.9%) and germacrene D (5.8â7.1%) were the main constituents in the oils obtained from fresh unripe, fresh ripe and air-dried ripe fruits.
