ANTIFUNGAL PHLOROGLUCINOL DERIVATIVES AND LIPOPHILIC FLAVONOIDS FROM HELICHRYSUM DECUMBENS

From the aerial parts of Helichrysum decumbens, three new antifungal phloroglucinol derivatives have been identified.Their structures have been established by UV, IR, EIMS, FAB-MS, 1H NMR and 13C NMR techniques.In addition, the highly methylated flavonoids 3,5-dihydroxy-6,7,8-trimethoxyflavone, 5,7-dihydroxy-3,6,8-trimethoxyflavone and 3,5-dihydroxy-6,7-dimethoxyflavone have been detected, the latter being a new naturally occurring compound.The phloroglucinols prevented the growth of Cladosporium herbarum in a bio-assay.These secondary metabolites are externally deposited on the plant surfaces.
