 +An absolute obtained from W.floribunda petals (Iwate, Japan; hexane and ethanol, 1.4g from 14kg petals) was fractionated and analyzed by GC, GC/MS, IR and NMR. The absolute had an odor similar to that of the natural wisteria flower. Main components were palmitic acid (28.5%), methyl palmitate 14.0%), 2-phenylethanol (4.4%), benzyl benzoate (3.9%), 1-phenyl-2,3-butandiol (threo 3.6%, erythro 0.8%), cinnamyl benzoate (3.3%), anisaldehyde (1.8%), and 2-phenylethyl benzoate (1.6%). "In contrast, benzyl cyanide, benzothiazole, methyl jasmonate, cis-jasmone and 3-hydroxy-4-phenyl-2-butanone were identified as the characteristic odor constituents of the flower." \\
