(R)-(+)-Dihydro-alpha-ionone - Floral, violet-type odor with slightly fruity aspects. Also possesses a woody side, but less pronounced than in dihydro-beta-ionone. Odor Threshold = 31 ppb in air = (1'R)-(+)-4-(2',6',6'-Trimethyl-cyclohex-2-enyl)-butan-2-one  Ref: Elisabetta Brenna, Claudio Fuganti, Stefano Serra, and Philip Kraft, Optically Active Ionones and Derivatives: Preparation and Olfactory Properties, Eur.
