Common Name1,2',5',8,10'-pentahydroxy-3,7'-dimethoxy-2',6-dimethyl-1',3'-dihydro-10h-[2,9'-bianthracene]-4',9-dione
DescriptionAnhydrophlegmacin B2 belongs to the class of organic compounds known as arylnaphthalene lignans. These are lignans containing the arylnaphthalene skeleton, especially 9-(2H-1,3-benzodioxol-5-yl)-1H,3H-naphtho[2,3-c]furan-1-one or a derivative thereof. Arylnaphthalene lignans occur in nature and exhibit diverse biological activities. 1,2',5',8,10'-pentahydroxy-3,7'-dimethoxy-2',6-dimethyl-1',3'-dihydro-10h-[2,9'-bianthracene]-4',9-dione is found in Senna multiglandulosa. Anhydrophlegmacin B2 is an extremely weak basic (essentially neutral) compound (based on its pKa).
