Natural Product Identification
Common Name5,6-Dehydrokawain
Description5,6-Dihydro-5-hydroxy-6-methyl-2H-pyran-2-one, also known as 56-dehydrokawain or (e)-4-methoxy-6-(2-phenylethenyl)-2H-pyran-2-one, belongs to the class of organic compounds known as kavalactones. These are lactones, which is structurally characterized by a benzene ring and a pyranone moiety, linked to each other to form a 4-methoxy-6-(2-phenylethyl)-2H-pyran-2-one skeleton. 5,6-Dihydro-5-hydroxy-6-methyl-2H-pyran-2-one is an extremely weak basic (essentially neutral) compound (based on its pKa). Outside of the human body, 5,6-Dihydro-5-hydroxy-6-methyl-2H-pyran-2-one has been detected, but not quantified in, beverages. This could make 5,6-dihydro-5-hydroxy-6-methyl-2H-pyran-2-one a potential biomarker for the consumption of these foods. 5,6-Dehydrokawain is found in Alpinia blepharocalyx, Alpinia mutica, Alpinia roxburghii, Alpinia zerumbet, Aniba firmula, Boesenbergia rotunda, Alpinia speciosa , Lindera umbellata , Persicaria lapathifolia, Piper cubeba, Piper lolot, Piper methysticum and Piper sanctum. Found in kava (Piper methysticum).
