Geosmin

[4S-(4alpha,4aalpha,8abeta)]-Octahydro-4,8a-dimethyl-4a(2H)-naphthalenol

C12H22O (182.1670562)


Geosmin is found in corn. Implicated in off-flavour of shellfish, freshwater fish, drinking water and some vegetables.Geosmin, which literally translates to "earth smell", is an organic compound with a distinct earthy flavour and aroma, and is responsible for the earthy taste of beets and a contributor to the strong scent that occurs in the air when rain falls after a dry spell of weather (petrichor) or when soil is disturbed. The human nose is extremely sensitive to geosmin and is able to detect it at concentrations as low as 5 parts per trillion. Implicated in off-flavour of shellfish, freshwater fish, drinking water and some vegetables

Beta-cubebene, also known as (-)-B-cubebene, is a member of the class of compounds known as sesquiterpenoids. Sesquiterpenoids are terpenes with three consecutive isoprene units. Beta-cubebene is a citrus and fruity tasting compound and can be found in a number of food items such as sweet basil, roman camomile, pot marjoram, and sweet bay, which makes beta-cubebene a potential biomarker for the consumption of these food products. Beta-cubebene can be found primarily in saliva. Piper cubeba, cubeb or tailed pepper is a plant in genus Piper, cultivated for its fruit and essential oil. It is mostly grown in Java and Sumatra, hence sometimes called Java pepper. The fruits are gathered before they are ripe, and carefully dried. Commercial cubebs consist of the dried berries, similar in appearance to black pepper, but with stalks attached – the "tails" in "tailed pepper". The dried pericarp is wrinkled, and its color ranges from grayish brown to black. The seed is hard, white and oily. The odor of cubebs is described as agreeable and aromatic and the taste as pungent, acrid, slightly bitter and persistent. It has been described as tasting like allspice, or like a cross between allspice and black pepper . beta-Cubebene belongs to the class of organic compounds known as sesquiterpenoids. These are terpenes with three consecutive isoprene units.

C15H24O (220.18270539999997)


Spathulenol is a tricyclic sesquiterpenoid that is 4-methylidenedecahydro-1H-cyclopropa[e]azulene carrying three methyl substituents at positions 1, 1 and 7 as well as a hydroxy substituent at position 7. It has a role as a volatile oil component, a plant metabolite, an anaesthetic and a vasodilator agent. It is a sesquiterpenoid, a carbotricyclic compound, a tertiary alcohol and an olefinic compound. Spathulenol is a natural product found in Xylopia aromatica, Xylopia emarginata, and other organisms with data available. See also: Chamomile (part of). A tricyclic sesquiterpenoid that is 4-methylidenedecahydro-1H-cyclopropa[e]azulene carrying three methyl substituents at positions 1, 1 and 7 as well as a hydroxy substituent at position 7. Spathulenol is found in alcoholic beverages. Spathulenol is a constituent of Salvia sclarea (clary sage).

Delta-selinene, also known as delta-selinen, is a member of the class of compounds known as eudesmane, isoeudesmane or cycloeudesmane sesquiterpenoids. Eudesmane, isoeudesmane or cycloeudesmane sesquiterpenoids are sesquiterpenoids with a structure based on the eudesmane skeleton. Delta-selinene can be found in allspice, lovage, and wild celery, which makes delta-selinene a potential biomarker for the consumption of these food products. Delta-selinene, also known as δ-selinen, is a member of the class of compounds known as eudesmane, isoeudesmane or cycloeudesmane sesquiterpenoids. Eudesmane, isoeudesmane or cycloeudesmane sesquiterpenoids are sesquiterpenoids with a structure based on the eudesmane skeleton.
