Flavonoids as chemotaxonomic markers for Asteraceae.

Biochem Syst Ecol 2001 Oct;29(9):947-957

Instituto de Química, Universidade de São Paulo, Caixa Postal 26077, 05513-970, São Paulo, Brazil

Flavonoids have been shown to be good taxonomic markers for Asteraceae. More than 800 compounds comprising 4700 flavonoid occurrences were included in a computational system specially made for chemotaxonomic purposes. Some implications of flavonols, flavones and other types as well as structural features of them are discussed for tribes and subtribes of Asteraceae. Read More

The role of lipophilic and polar flavonoids in the classification of temperate members of the Anthemideae.

Biochem Syst Ecol 2001 Oct;29(9):929-945

Plant Science Laboratories, Department of Botany, The University of Reading, Whiteknights, P.O. Box 221, Reading, RG6 6AS, Berkshire, UK

Lipophilic and vacuolar flavonoids were separately identified in representative temperate species of the genera Anthemis, Chrysanthemum, Cotula, Ismelia, Leucanthemum and Tripleurospermum. The four Anthemis species investigated variously produced four main surface constituents, in leaf and flower: santin, quercetagetin 3,6,3'-trimethyl ether, scutellarein 6,4'-dimethyl ether and 6-hydroxyluteolin 6,3'-dimethyl ether. By contrast, surface extracts of disc and ray florets of the species of Chrysanthemum, Cotula, Ismelia, Leucanthemum and Tripleurospermum surveyed yielded five common flavones in the free state: apigenin, luteolin, acacetin, apigenin 7-methyl ether and chrysoeriol.

Phytoecdysteroids in seeds of Lloydia serotina (Liliaceae).

Biochem Syst Ecol 2001 Oct;29(9):923-928

Department of Biological Sciences, University of Exeter, Hatherly Laboratories, Prince of Wales Road, Exeter, EX4 4PS, Devon, UK

Seeds of a number of species in the Liliaceae (sensu Brummitt, 1992) were examined for the presence of ecdysteroid agonist and antagonist activities. No species were antagonistic to 20-hydroxyecdysone action on the ecdysteroid-responsive Drosophila melanogaster B(II) cell line and only one extract, that of Lloydia serotina, was agonistic. This activity is attributable to the presence of phytoecdysteroids as detected by ecdysteroid-specific radioimmunoassay and the agonist version of the B(II) bioassay. Read More

Differential expression for tissue-specific isozymes in three species of Hypostomus Lacépède, 1803 (Teleostei: Loricariidae).

Biochem Syst Ecol 2001 Oct;29(9):911-922

Nupélia (Research Center on Limnology, Ichthyology and Aquaculture), Brazil

The expression patterns of 14 enzymatic systems in skeletal muscle, liver and heart tissues of three species of Hypostomus from the Iguaçu River basin (Brazil) were investigated. Although the patterns were similar for the three species, different tissues showed differential expressions, and the data showed that differential tissue expressions of isoperoxidases may be due to preferential combination or association of polypeptide subunits. The detected patterns for SOD isozymes showed that the quaternary structures of these enzymes were in disagreement with the subunit number reported for the majority of other vertebrate groups.

Phylogenetic relationships among four species of Mullidae (Perciformes) inferred from DNA sequences of mitochondrial cytochrome b and 16S rRNA genes.

Biochem Syst Ecol 2001 Oct;29(9):901-909

Department of Genetics, Development and Molecular Biology, School of Biology, Aristotle University of Thessaloniki, 54006 Thessaloniki, Macedonia, Greece

DNA sequence comparisons of two mitochondrial DNA genes were used to infer phylogenetic relationships among four species of mullids. Approximately 238bp of the mitochondrial 16S ribosomal RNA (rRNA) and 261bp of the cytochrome b (cytb) genes were sequenced from representatives of three mullid genera (Mullus, Upeneus, Pseudopeneus), present in the Mediterranean Sea. Trees were constructed using three methods: maximum likelihood (ML), neighbor joining (NJ) and parsimony (MP). Read More

Flavonoid sequestration by the common blue butterfly Polyommatus icarus: quantitative intraspecific variation in relation to larval hostplant, sex and body size.

Biochem Syst Ecol 2001 Oct;29(9):875-889

Lehrstuhl Pharmazeutische Biologie, Julius-von-Sachs-Institut der Universität Würzburg, Julius von Sachs-Platz 2, D-97082, Würzburg, Germany

Common blue butterflies (Polyommatus icarus) sequester flavonoids from their larval food and store these pigments as part of their adult wing colouration. Insects were reared on 10 different diets to assess effects of host plants on variation in flavonoid sequestration in this moderately polyphagous butterfly. Rearing experiments revealed an unexpectedly large gradient in flavonoid richness, ranging from individuals with high flavonoid loads (reared on inflorescences of Medicago sativa, Trifolium repens, T.

Faculty of Agriculture, Yamagata University, Wakaba-machi 1-23, 997, Tsuruoka, Japan

The leaf terpenes in Thujopsis dolabrata from all regions in Japan were analyzed using GC and GC-MS. The results show that the major constituents of the diterpene hydrocarbon fraction in this conifer are dolabradiene, hibaene, rimuene, 13-epi-dolabradiene and abietatriene. There were wide variations in the contents of the constituents among individuals and habitats. Read More

A chemosystematic study of the subgenus Oporinia of the genus Leontodon (Asteraceae) was performed, using flavonoids and phenolic acids in the flowerheads as diagnostic characters. A total of 44 samples from nine different Oporinia taxa were analyzed. Five luteolin-derivatives (luteolin, luteolin 7-O-beta-D-gentiobioside, luteolin 7-O-beta-D-glucoside, luteolin 7-O-beta-D-glucuronide, and luteolin 4'-O-beta-D-glucoside) and four caffeic acid derivatives (caffeoyl tartaric acid, chlorogenic acid, cichoric acid, and 3,5-dicaffeoylquinic acid) were identified in crude extracts by means of HPLC retention times, on-line UV spectra and on-line MS spectra.

Staphylococcus aureus MDR efflux pump inhibitors from a Berberis and a Mahonia (sensu strictu) species.

Biochem Syst Ecol 2001 Aug;29(8):793-798

Department of Chemistry, Colorado State University, 80523-1872, Fort Collins, CO, USA

Bioactive fractionation, based on multi-drug resistance (MDR) pump inhibition in Staphylococcus aureus, resulted in the isolation of the active inhibitors 5'-methoxyhydnocarpin-D from leaves of Berberis (formerly Mahonia) trifoliolata and pheophorbide a from Berberis fendleri. The hydnocarpin derivative was not found in the latter species. Pheophytin a (the phytol derivative of pheophorbide a) was identified from both species, but it proved to have no MDR pump inhibitory activity. Read More

An electrophoretic genetic analysis utilising starch gel electrophoresis was employed to assess clonality in endangered Zieria baeuerlenii populations distributed over an area of less than a kilometre square in Nowra (NSW). Eleven enzymes systems encoded by 19 loci (41 alleles) when assayed to estimate levels of genetic diversity within and among populations, revealed moderate levels of genetic diversity. Despite finding seven loci being fixed at a particular locus, 20 unique multilocus genotypes/clones restricted to a particular population were detected within a sample of 179 ramets collected from throughout the range of the species.
