Chemical Information
FooDB NameSantamarin
DescriptionSantamarin, also known as (+)-santamarine or balchanin, belongs to eudesmanolides, secoeudesmanolides, and derivatives class of compounds. Those are terpenoids with a structure based on the eudesmanolide (a 3,5a,9-trimethyl-naphtho[1,2-b]furan-2-one derivative) or secoeudesmanolide (a 3,6-dimethyl-5-(pentan-2-yl)-1-benzofuran-2-one derivative) skeleton. Santamarin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Santamarin can be found in sweet bay, which makes santamarin a potential biomarker for the consumption of this food product.
