抄録

The antimicrobial substances in sunflower (Helianthus annuus)were investigated. Two antifungal benzopyran derivatives, 6-acetyl-2, 2-dimethyl-1, 2-benzopyran (1) and 6-acetyl-7-hydroxy-2, 2-di-methyl-1, 2-benzopyran (2) were isolated f om the ethanol extract of sunflower receptacles. The antimicrobial activities of isolated compounds 1 and 2 and their related compounds (precocenes) were evaluated by the paper disk method, using Pyrircularia oryzae as the test fungus.
