Isolation and structural elucidation of antimicrobial compounds from buckwheat hull

Three new compounds were isolated from themethanol extracts of buckwheat (Fagopyrum esculentum)hull, and their structures were determined to be 6,7-dihydroxy-3,7-dimethyl-octa-2(Z),4(E)-dienoic acid (1), 6,7-E),4(E)-dienoic acid (2), and4,7-dihydroxy-3,7-dimethyl-octa-2(E),5(E)-dienoic acid (3)by NM...

Summary:Three new compounds were isolated from themethanol extracts of buckwheat (Fagopyrum esculentum)hull, and their structures were determined to be 6,7-dihydroxy-3,7-dimethyl-octa-2(Z),4(E)-dienoic acid (1), 6,7-E),4(E)-dienoic acid (2), and4,7-dihydroxy-3,7-dimethyl-octa-2(E),5(E)-dienoic acid (3)by NMR and MS spectroscopic analyses. These compoundsat 50 g concentration showed antimicrobial activity againstStaphylococcus aureus, demonstrated by the paper discmethod. KCI Citation Count: 1
