background: taxus species are important due to their content of taxol, baccatin iii, 10- deacetyl baccatin and other taxoids suitable to change to active pharmaceutical ingredients, which are used as anti-neoplastic agents. investigations on taxoids carried out during the past four decades, resulted in identification of more than 350 taxoids. objective: this study aimed to isolate and identify ...

Taxol is a known drug, approved by the food and drug administration in 1992 for the treatment of a wide range of cancers. Taxol is obtained from the taxus plant. Taxus plant has a very long life cycle and the production of taxol from the plant is a tedious process. In this study, we have tried to find new species of taxus which can be able to produce taxol and can overcome the burden of Taxus b...

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 s...

Flavanols and flavonols of mitotic and post-mitotic nuclei in needles of Taxus baccata L., Tsuga canadensis L., and slow growing dwarf genotypes of both genera are investigated histochemically. The flavanols of nuclear chromatins and in the vacuoles stain blue with the p-dimethylamino-cinnamaldehyde (DMACA) reagent. Flavonols do not react with the reagent but owing to their UV absorbance they c...
