Taxine B (3), isolated from the dried needles of Taxus baccata, was converted into six novel 7-deoxypaclitaxel analogs, 20, 21a,b, and 23-25, that have structural changes at C1, C2, and C4. A method for the introduction of the benzoyl function at C2, via a benzylidene acetal at C1-C2, will be revealed. All compounds showed very little or no measurable cytotoxic activity against some well-charac...

Genetic markers used in combination with network analysis can characterize the fine spatial pattern of seed dispersal and assess the differential contribution of dispersers. As a case study, we focus on the seed dispersal service provided by a small guild of frugivorous birds to the common yew, Taxus baccata L., in southern Spain. We build the spatial networks of seed dispersal events between t...

In vitro cultivated plant cells and tissues were found to synthesize polyisoprenoids. Taxus baccata suspension cell cultures accumulated polyisoprenoids of the same pattern as the parental tissue; methyl jasmonate or chitosan treatment almost doubled their content. All the root cultures studied accumulated dolichols as predominant polyisoprenoids. Roots of Ocimum sanctum grown in vitro accumula...

Istraživanje vaskularne flore provedeno je na dijelu južnih padina planine Ivanščice iznad grada Zlatara u listopadu 2022. godine. Zabilježeno ukupno 85 svojti unutar 47 porodica. S obzirom broj najzastupljenije su bile porodice Rosaceae, Asteraceae te Aspleniaceae, Fabaceae, Fagaceae i Lamiaceae. Biljne svojte s životni oblik uglavnom hemikriptofiti (35,7 %) fanerofiti (33,3 %), dok terofiti n...
