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...

The Beckman antistreptolysin O kit agreed within one-dilution increment for 70% of the specimens tested. The antideoxyribonuclease B kit agreed within onedilution increment for 96% of the specimens tested.

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 ...

Lomefloxacin (SC-47111; NY-198) is a new difluoroquinolone agent. It inhibited 90% of Escherichia coli, Klebsiella spp., Enterobacter spp., Citrobacter spp., Proteus mirabilis, Morganella morganii, Proteus vulgaris, Serratia marcescens, Salmonella spp., Shigella spp., Aeromonas spp., Yersinia spp., Haemophilus influenzae, and Neisseria gonorrhoeae at less than or equal to 2 micrograms/ml. Lomef...

Earthworms are soil invertebrates that play a key role in recycling organic matter in soils. In Nigeria, earthworms include Libyodrillus violaceous. Aerobic and anaerobic bacterial counts, as well as fungal counts of viable microorganisms in soils and gut sections, were made on twenty L. violaceous collected from different sites on the campus of the University of Agriculture, Abeokuta, Nigeria....

Acropora and Porites corals are important reef builders in the Indo-Pacific and Caribbean. Bacteria associated with mucus produced by Porites spp. and Acropora spp. from Caribbean (Punta Maroma, Mexico) and Indo-Pacific (Hoga and Sampela, Indonesia) reefs were determined. Analysis of pyrosequencing libraries showed that bacterial communities from Caribbean corals were significantly more diverse...

Combining different preservative treatments for improving quality and safety of fishery products increasingly receives global research attention. Consistent with this pursuit, the current research was undertaken to determine the effects of different ozonized slurry-ice treatments and superchilling (-1°C) storage on microbial spoilage of European anchovy (Eugraulis encrasicolus) and sardine (Sar...
