β-thujone
Thujone () is a ketone and a terpene, monoterpene that occurs predominantly in two diastereomeric (epimeric) forms: (−)-α-thujone and (+)-β-thujone. Though it is best known as a chemical compound in the spirit absinthe, it is unlikely to be responsible for absinthe's alleged stimulant and psychoactive effects due to the small quantities present. Thujone acts on the neurotransmitter gamma-aminobutyric acid GABA receptors, (GABA) as an antagonist (opposite to the effects of alcohol). As a competitive antagonist of GABA, thujone alone is considered to be convulsant, though by interfering with the inhibitory transmitter GABA, it may convey stimulating, mood-elevating effects at low doses. It is also used in perfumery as a component of several essential oils. In addition to the naturally occurring (−)-α-thujone and (+)-β-thujone, two other forms are possible: (+)-α-thujone and (−)-β-thujone. In 2016, they were found in nature as well, in ''Salvia officinalis''. File:(-)- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artemisia Absinthium
''Artemisia absinthium'' (wormwood, grand wormwood, absinthe, absinthium, absinthe wormwood, mugwort, wermout, wermud, wormit, wormod) is a species of ''Artemisia'', native to temperate regions of Eurasia and North Africa, and widely naturalized in Canada and the northern United States. It is grown as an ornamental plant and is used as an ingredient in the spirit absinthe and some other alcoholic beverages. Etymology ''Artemisia'' comes from Ancient Greek ἀρτεμισία, from Ἄρτεμις (Artemis). In Hellenistic culture, Artemis was a goddess of the hunt, and protector of the forest and children. The name ''absinthum'' comes from the Ancient Greek ἀψίνθιον, meaning the same. An alternative derivation is that the genus was named after Queen Artemisia, who was the wife and sister of Mausolus, ruler of Caria. The word "wormwood" may come from Middle English ''wormwode'' or ''wermode''. Webster's Third New International Dictionary attributes the etymology to Old ...
