Secondary metabolites
''Gnaphalium'' species are known to contain flavonoids and diterpenes. Recently, two unique caffeoyl-D-glucaric acid derivatives, leontopodic acid and leontopodic acid B formerly only known from ''Leontopodium alpinum'' (L.) Cass. were detected in various species of ''Gnaphalium'' together with similar formerly unknown compounds.
