[Chemical Properties]

Rhodinyl isobutyrate has a fruity, sweet, floral odor with a fruity, floral, pineapple-like flavor, intensely sweet.
[Occurrence]

Has apparently not been reported to occur in nature.
[Definition]

ChEBI: Rhodinyl isobutyrate is a carboxylic ester.
[Preparation]

From rhodinol and isobutyric anhydride.
[Metabolism]

Open-chain olefinic terpene esters are presumably hydrolysed to the alcohol and the acid (Fassett, 1963). In the rabbit, the open-chain terpenes undergo ω-oxidation (Williams, 1959).
