Flavonoids from the genus Taxus.

چکیده
From the needles of Taxus baccata the following flavonoids were isolated: 3-O-rutinosides quercetin, myricetin and kaempferol, 7-O-glucosides kaempferol and quercetin, kaempferol, quercetin, myricetin. The composition of flavonols and biflavones in some of the species of the genus Taxus, namely T. celebica, T. cuspidata, T. media and cultivar varieties T. baccata 'Aurea', T. baccata 'Aurea decora', T. baccata 'Elegantissima', T. baccata 'Fastigiata', T. baccata 'Pyramidalis', T. media 'Hatfieldii' were compared by HPLC separation.

DNA and Flavonoids Leach out from Active Nuclei of Taxus and Tsuga after Extreme Climate Stresses.
Severe over-stresses of climate caused dramatic changes in the intracellular distribution of the flavonoids. This was studied in needles from the current year's growth of the following species and varieties: Tsuga canadensis, Taxus baccata, T. aurea, T. repens, T. nana, and T. compacta. The mode of steady changes in flavonoids was evaluated by microscopic techniques. Most of the flavonoids stai...
متن کاملTaxane Diterpenoids from Taxus baccata L. Growing in Iran
Background: There are eight Taxus species and two hybrids in the world and Taxus baccata L. (European yew) is the single representative in Iran. Until now, a large number of taxoids possessing different skeleton systems, as well as lignans, flavonoids, steroids and sugar derivatives have been isolated from various Taxus species. Taxoids are highly oxygenated diterpenes isolated from different...

A cladistic analysis of the medicinal plant Taxus, using the sequences of one chloroplast (trnS-trnQ spacer) and three nuclear taxadiene synthase (TS), 10-deacetylbaccatin III-10beta-O-acetyltransferase (DBAT), and 18S rDNA) molecular markers, was carried out by distance, parsimony, likelihood, and Bayesian methods. Three of the four New World species (T. brevifolia, T. floridana and T. globosa...

Eight samples of flowering tops from six species of the genus Crataegus L., commonly called Hawthorn, from different geographic locations of Iran were standardized according to German Pharmacopoeia monograph on Crataegi folium cum flore (hawthorn leaf with flower) by high-performance thin-layer chromatograph-ic (HPTLC) fingerprinting combining with digital scanni...
متن کاملSensitivity Differences and Accumulation of Screening Compounds in Three Conifer Plants under Enhanced UV-B Radiation
Responses of American arborvitae (Thuja occidentalis), common yew (Taxus x media) and juniper (Juniperus communis) to enhanced UV-B irradiance were studied. Control plants were grown without UV treatment, but at identical PhaR and temperature regimes. Visual symptoms of the ultraviolet effect noted on Thuja shoots as brown/red discolouration were correlated with the accumulation of phenolic com...
