Chemodiversity of exudate flavonoids in Cassinia and Ozothamnus (Asteraceae, Gnaphalieae).
The lipophilic exudates deposited on aerial parts of four species of Cassinia and twelve species of Ozothamnus (Asteraceae, Gnaphalieae) have been analyzed for the presence of flavonoid aglycones and some other phenolics. A total of 55 flavonoids were identified, including several rare flavonols. Flavonols are prevailing over flavones, and 8-O-substitution is dominant in both groups. Ozothamnus...
متن کاملPhylogeny of South African Gnaphalieae (Asteraceae) based on two noncoding chloroplast sequences.
The Gnaphalieae are a group of sunflowers that have their greatest diversity in South America, Southern Africa, and Australia. The objective of this study was to reconstruct a phylogeny of the South African Gnaphalieae using sequence data from two noncoding chloroplast DNA sequences, the trnL intron and trnL/trnF intergenic spacer. Included in this investigation are the genera of the Gnaphaliea...
متن کاملExudate flavonoids in some Gnaphalieae and Inuleae (Asteraceae).
Three members of the tribe Gnaphalieae and six members of the tribe Inuleae (Asteraceae) were analyzed for their exudate flavonoids. Whereas some species exhibit rather trivial flavonoids, others produce rare compounds. Spectral data of rare flavonoids are reported and their structural identification is discussed. 6-Oxygenation of flavonols is a common feature of two Inula species and Pulicaria...
متن کاملNOTES ON SOME SPECIES OF THE GENUS EUPHORBIA IN IRAN
During the study on newly collected and herbarium specimens belonging to the genus Euphorbia, three species, namely, E. gorenfloti, E. cheirolepioides and E. splendida were found to be synonymous with E. chamaepeplus, E. grossheimii and E. decipiens, respectively. Euphorbia sahendi as an interesting and rare species has been recognized after long time again among my material and Euphorbia delto...
متن کاملMolecular phylogeny and taxonomy of Eurasian Neoerysiphe species infecting Asteraceae and Geranium
Because Eurasian samples of Neoerysiphe collected on the Asteraceae were not identical in morphology, the molecular and morphological differences among these specimens were compared with those of the American N. cumminsiana. Neoerysiphe on Asteraceae was found to consist of at least four different species. Three of them are described as new species, viz. N. hiratae, N. joerstadii, and N. nevoi....
