Essential oil of Amorpha fruticosa L.

The essential oils from the flowers, leaves and fruits of Amorpha fruticosa L. were investigated by GC, GC/MS and H-1-C-13-NMR spectroscopy. About 70 constituents were identified in each oil. The major components of the flowe r oil were alpha -eudesmol (15.8%), beta -eudesmol (7.8%), delta -cadinene (6.2%) and (E)-nerolidol (6.1%). The leaf oil contained mainly alpha -eudes mol (13.9%), (E)-beta -ocimene (11.9%), and alpha -pinene (11.8%). In the r ipe fruit oil alpha -pinene (19.3-19.6%), myrcene (17.7-18.7%) and delta -c adinene (6.2-6.9%) dominated.
