Natural Product Identification
Common Name6-Hydroxy-7,8-dimethoxy-4-phenylcoumarin
DescriptionKuhlmannin belongs to the class of organic compounds known as neoflavones. These are neoflavonoids with a structure based on the 4-phenylcoumarin skeleton. Thus, kuhlmannin is considered to be a flavonoid lipid molecule. 6-Hydroxy-7,8-dimethoxy-4-phenylcoumarin is found in Dalbergia nigra, Machaerium kuhlmannii, Machaerium nictitans, Machaerium pedicellatum and Piptadenia macrocarpa. Kuhlmannin is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral.
