• 説明

  Nootkatone has a pleasant taste. It may be prepared by oxidation of valencene (a sesquiterpene) with tertiary butyl chromate.

• 化学的特性

  NOOTKATONE has been isolated from grapefruit peel and juice and identified in other citrus oils as well. The commercially available product is a colorless to yellowish liquid with a typical grapefruit odor.
  Nootkatone can be prepared by oxidation of valencene, a sesquiterpene hydrocarbon isolated from orange oils. The oxidation can be accomplished either by chemical or by biotechnological methods.
  Nootkatone is used for flavoring beverages.

• 天然物の起源

  Reported found in grapefruit oil and juice; traces are also reported found in the oils of bergamot, lemon, lime, orange and tangerine; also reported formed in canned orange juice on storage.

• 定義

  ChEBI: A sesquiterpenoid that is 4,4a,5,6,7,8-hexahydronaphthalen-2(3H)-one which is substituted by methyl groups at positions 4 and 4a, and by an isopropenyl group at position 6 (the 4R,4aS,6R stereoisomer).

• 製造方法

  By oxidation of valencene (a sesquiterpene) with tertiary butyl chromate.

• 一般的な説明

  (+)-nootkatone, a bicyclic conjugated sesquiterpene ketone with a grapefruit-like flavor, is commonly used in fragrance, food, cosmetics and pharmaceutical industry. It can be synthesized from (+)-valencene via biotransformation. (+)-nootkatone is the active ingredient responsible for the antiplatelet effect of Cyperus rotundus, a well-known oriental traditional medicine. It also shows promising efficacy against Staphylococcus aureus biofilms.
