Wisteria floribunda (Willd.) DC. - syn. Glycine floribunda Willd.; Kraunhia floribunda (Willd.) Taub. - Fabaceae
Japanese wisteria, フジ fuji (jap.), Japanischer Blauregen, Japanische Wisteria
Deciduous woody climber, native to Japan and Korea, cultivated elsewhere as ornamental; leaves imparipinnate, leaflets oblong; flowers in long racemes, 1.5-2cm, fragrant, corolla blue-white.
The headspace of Wisteria floribunda flowers contained (S)-(+)-linalool (18.9%; 99.0%ee; coriandrol) with its flowery green note also known from green cardamom and jasmine absolute.

Of the 22 volatiles emitted from Japanese wisteria flowers and collected using a dynamic headspace technique, linalool (11.2µg/h/g), (E)-β-ocimene (4.0), benzyl alcohol (2.7) and 2-undecanone (0.9) were the most abundant. Sesquiterpenes including α-copaene, (E)-β-caryophyllene, α-humulene, germacrene D, and elemol were exclusively detected from japanese wisteria, whereas (E)-β-farnesene was detected from both chinese wisteria and japanese wisteria. Other compounds present in W.floribunda flower scent were (Z)-3-hexenyl acetate, methyl hexadecanoate, nonanal, decanal, indole, methyl chavicol, benzyl isocyanide and 1-nitro-2-phenylethane.

The main components of the volatiles from W.floribunda flowers were ocimene, (Z)-3-hexenyl acetate, limonene, α-pinene, camphene, (E)-3-caren-2-ol, 2-nonanone, 1,8-cineole, myrcene, and benzaldehyde.
