Coumarins anise

Anisic aldehyde, CgHgOj, is a methyl ether of para-oxy-benzaldehyde, which is found to a small extent in the oils of fennel and aniseed. It is manufactured on an extensive scale artificially, and is the basis of all the perfumes of the hawthorn or May blossom type. It is known commercially as aubepine . A certain amount of anisic aldehyde is obtained as a by-product in the manufacture of coumarin, but the greater- part of it is obtained by very careful oxidation of anethol, the characteristic constituent of aniseed oil, which has the constitution—... 

This lactone has an odor reminiscent of coconut it is one of the flavor constituents of fruits, distilled beverages and wine. The sensory properties, mentioned by Dufosse et al. (1994) are strongly coconut, fatty, anise, liquorice, fruity, almond. Mosandl and Gunther (1989) described the odor as strong, sweet, soft-coconut with fatty-milky aspects for the (R)-enantiomer and fatty moldy, with a weak coconut note for the (S), less intense than the (R). The flavor of the (7 )-lactone is herbal, coumarinic, coconut and of the (5) coconut, creamy, dairy, mouthfeel (Chemisis, 1993). The threshold is supposed to be very low (estimated at 30ppb in wine by Nakamura et al., 1988). 

The odor is intensively sweet floral, yet somewhat hay-like , generally described as hawthorne-like (Arctander, 1967). At the sniffing port of a chromatograph, the odor perception is sweet, minty with a dilution factor more important with the powder than with the brew of an arabica (Blank et a/., 1992b). The flavor is described as sweet, anisic, coumarinic (Chemisis, 1989).
