Title: A chemical appraisal via leaf flavonoids of dahlgren's Liliiflorae
Abstract: Leaf flavonoids have been identified in 91 species of the new superorder Liliiflorae. The results have been combined with those obtained earlier on 181 species so that data are now available on 29 of the 52 families. The flavonols quercetin and kaempferol occur in about half the sample, while the flavones apigenin and luteolin are present in about a fifth. O-Methylated flavonoids (isorhamnetin, tricin, diosmetin, etc.) are uncommon, as are other classes of flavonoid. The rare flavonol, 3-O-methyl-8-C-methylquercetin, previously reported in Dasylirion acrotrichum, was found in three other members of the family Nolinaceae and seems to characterize it. Otherwise, the 29 families fall into two groupings: 23 with flavonols in the leaves and six with flavonols and flavones. The limited diversity in flavonoid patterns and in other chemical features within these plants argues for a more conservative treatment at the family level.
