Elderberry (Sambucus nigra) and black locust (Robinia pseudoacacia) agglutinins, which are abundantly present in the bark of both species, display seasonal fluctuations with regard to their content in this tissue. These seasonal changes result apparently from a circa-annual rhythm of lectin accumulation and depletion during autumn and spring, respectively. Because the bark of trees can be consi...
BACKGROUND AND AIMS Angiosperms with simple vessel perforations have evolved many times independently of species having scalariform perforations, but detailed studies to understand why these transitions in wood evolution have happened are lacking. We focus on the striking difference in wood anatomy between two closely related genera of Adoxaceae, Viburnum and Sambucus, and link the anatomical d...
در این تحقیق، تعداد شش آرایه از قارچ های میکرومیست استان گلستان که طی فصول بهار و تابستان سال 1389 جمع آوری گردیده اند، معرفی میشوند. گونههای melanospora zobelii روی قارچ دنبلان صحرایی picoa lefebvrei،diachea leucopodiaروی sambucus nigra،choanephora cucurbitarumروی brassica oleracea، trichurus spiralis روی پوست طوقه prunus domestica، غده solanum tuberosumو بذر gossypium hirsutumو dictyosporiu...
In this study, S. nigra L. and ebulus (Adoxaceae) species belonging to the Sambucus genus were examined. Species of collected from northern Turkey anatomical comparisons made. Stem leaf anatomy examined by light microscopy. The plants have woody stem anatomy. druse crystals which are main characters observed in taxa. Differences found number cells vascular bundles, arrangement druze crystals, s...
A new lignan glycoside, (-)-massoniresinol 4'-O-beta-D-glucopyranoside (4), was isolated, together with six known ones (1-3, 5-7), from the leaves of Sambucus sieboldiana. Their structures were established on the basis of chemical and spectral data.
Distribution, biodiversity and biotechnology of Sambucus ebulus L. are not investigated yet (Caprifoliaceae family).There are 20-25 species of the genus of Sambucus L. are known in the world but in Iran, it is etermined only one species, Sambucus ebulus, that distributed in three Northern Provinces next to Caspian Sea (Golestan, Mazandaran and Gillan province). In this short paper, Distribution...
The changes in total polyphenolics in elderberry (Sambucus nigra) following treatment with various doses of pulsed ultraviolet rays (UV) were investigated. Four pulsed UV durations (5, 10, 20, 30 seconds) at three energy dosages (4500, 6000, 11,000 J/m/pulse) were considered for the research. All treated elderberry fruits were incubated for 24 h at room temperature (25 ̊C) following treatment to...
