Prenylfuranocoumarin-HMGA-flavonol glucoside conjugates and other constituents of the fruit peels of Citrus hystrix and their anticholinesterase activity

Sixteen compounds including dihydroxyprenylfuranocoumarins-HMGA-flavonol glucoside conjugates were isolated from Citrus hystrix. Some of the isolates were evaluated for their cholinesterase inhibitory activity and one compound possessing a 3-O-β-d-glucopyranosyl-3,5,7,4′-tetrahydroxy-6,8,3′-trimethoxyflavonol nucleus showed strong activity.
