Two novel anthocyanins, delphinidin 3-O-(6-O-(2-O-acetyl-α-rhamnopyranosyl)-β-glucopyranoside) and delphinidin 3-O-(6-O-(3-O-acetyl-α-rhamnopyranosyl)-β-glucopyranoside), were identified from the anthers of Tulipa gesneriana. These and delphinidin 3-O-(6-O-(α-rhamnopyranosyl)-β-glucopyranoside) made up over 80% of the anthocyanin content in the dark purple anthers and could be responsible for t...

Twenty-eight leaf and twig samples and one bark sample of Taxus baccata from the Ukraine (Crimea), Russia, and Georgia were analyzed for taxane compounds. Taxol and the related diterpenoid I 0-deacetylbaccatin III (baccatin Ill) were present in all samples and 20.7% of those samples exhibited a taxol content nearly equal to or greater than that obtained from the bark of the Pacific Yew, T. brev...

Taxol (paclitaxel) a diterpenoid is one of the most effective anticancer drugs identified. Biosynthesis of taxol was considered restricted to the Taxus genera until Stierle et al. discovered that an endophytic fungus isolated from Taxus brevifolia could independently synthesize taxol. Little is known about the mechanism of taxol biosynthesis in microbes, but it has been speculated that its bios...

Four lignan type compounds, lariciresinol, taxiresinol, isolariciresinol and 3-demethyl-iso-lariciresinol, were isolated from the heartwood of Taxus baccata L. (Taxaceae) growing in Turkey through chromatographic techniques. In vivo anti-ulcerogenic potency of these compounds was investigated on ethanol-induced ulcerogenesis model in rats at two different doses, 50 and 100 mg/kg. All compounds ...
