Three flavonoids, 5,7-dihydroxy-4 -methoxyflavone, 3,5,7-trihydroxy-4 -methoxyflavone and 3,5,7-trihydroxy-3 -methoxyflavone, were isolated in a bioguided study from the dichloromethane extract of Baccharis leptophylla [209]. Data on the activity of these compounds against Candida albicans. Trichophyton mentagrophytes. Trichophyton rubrum and Microsporum canum is reported. From another Baccharis species, Baccharis peduculata (Mill.) Cabrera., a flavone ether was isolated as an antifungal principle [223]. [Pg.491]

Pisutthanan et al. (27) isolated six flavonoids out of which three were reported in this plant for the first time. They include 3,5,4 -trihydroxy-7-methoxyflavanone 5,7,3 -trihydroxy-5 -methoxyflavanone and 3,5,7-trihydroxy-4 -methoxyflavanone. Ling et al.
