Gruezo and Keith E. Denford. Philippines Rushing Water Publishers 1995. pp. 151-170. "On hundred and forty-three natural populations representing six of seven taxa in subgenus Chamissonis Maguire of genus Arnica L. (Asteraceae) were surveyed for their foliar flavonoids. Eighteen flavonoids were identified six flavonol and six flavone glycosides, two methylated and four free aglycones. These are Quercetin 3, 7-0-diglucoside; Kaempferol 6-0-Me, 3-0-glucoside; 4', 7-diOH flavone, 3-O-flucoside; Luteolin 6-O-Me, 7-0-glucoside; Quercetin 3-0-diglucoside; Apigenin 4'-Me, 7-0-diglucoside; Luteolin 3', 7-O-glucoside; Kaempferol 3-O-glucoside; Luteolin 6-OH, 4'-Me; Luteolin 6-O-Me; Apigenin, Luteolin, Kaempferol and Quercetin. The chemosystematic relationships of taxa are discussed in the light of these findings. Western North America. Asteraceae. Flavonoid analysis. Luteolin. Denford, Keith E. author.
