Anaphalis margaritacea (L.) Benth. and Hook - syn.Gnaphalium margaritaceum L. - Asteraceae\\ (western) pearly everlasting, **Perlkörbchen**, Perlblume, Silberimmortelle Erect rhizomatous perennial, up to 90cm tall, native to North America, northeastern Asia, cultivated elsewhere as ornamental; leaves lanceolate or linear, sessile, acuminate, commonly less pubescent above than beneath, or glabrous above, margins often revolute; basal and lower cauline leaves soon deciduous; flowers terminal, clustered in short, broad inflorescences; flower heads 1 cm wide or less, numerous and crowded in a short broad inflorescens, involucre 5-7mm, bracts pearly-white; achenes papillate; seeds very fine, almost dust-like. "Anaphalis margaretacea was widely planted as an ornamental and escaped. It apparently naturalized from its native range in both Asia and North America; it is cultivated and naturalized in Europe." \\ [[http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=200023111]] The herb is used as an expectorant and astrin­gent, especially in homeopathy. \\ From the leaf and stem exudate (aceton extract of brownish resin of dried plant material) of A.margaritacea a number of flavonoid aglycones was isolated: Galangin-3-methyl ether, 6-hydroxy-galangin-3,6-dimethyl ether, 8-hydroxygalangin-3,8-dimethyl ether (gnaphalin), quercetin, 6-methoxy-galangin, 3,5,7-Trihydroxy-6,8-dimethoxy flavone, 5,7-dihydroxy-3,6,8-trimethoxy flavone (araneol), 5,7-dihydroxy-6-prenyl flavanone (6-prenyl-pinocembrin), 2',4',6'-trihydroxy-3'-prenyl-chalcone, 3,5-dihydroxy-6,7,8-trimethoxy flavone, galangin, and 8-methoxy galangin. \\ [Rare flavonoid aglycones from Anaphalis margaritacea and two Gnaphalium species., Wollenweber, E., Fritz, H., Henrich, B., Jakupovic, J., Schilling, G., Roitman, J.N., Zeitschrift für Naturforschung C, Vol.48, 1993, 420-420] \\ [[http://zfn.mpdl.mpg.de/xtf/data/Reihe_C/48/ZNC-1993-48c-0420.pdf]] {{:perlblume.jpg?500}} \\ Anaphalis margaritacea (L.)
