Carvone anise

Other synthetics with cost advantages and large volume productions are L-carvone [6485-40-17, the primary component in natural spearmint essence D-carvone [2244-16-8], the primary component in natural diU and caraway anethol [4180-23-8], in place of anise and fennel spices and smaller amounts of thymol [89-83-8] replacing thyme and disulfide synthetics for onion and gadic. AH of these synthetics must be labeled as artificial which may limit their use among consumers.

Determination of the following constituents are specifically mentioned in some monographs for quality assessment of the essential oils that will be discussed subsequently anethole in anise and star anise oils carvone in caraway, dill, and spearmint oils 1,8-cineole in cardamom, rosemary, and sage oils and linalool in coriander and basil oils. 

Anethole, anisaldehyde, and myristicin (in aniseed), along with z/-carvone (present in P. anisum plant), have shown mild insecticidal properties. In houseflies, the major (56% by weight) active insecticide in the oil from anise tops was shown to be frans-anethole. Anisaldehyde and anethole increased the toxicity to houseflies when applied at the same as various common insecticides. Anethole also inhibits growth of mycotoxin-producing Aspergillus species in culture. ...
