A New Ultra Rapid Screening Method for Olive Oil Health Claim Evaluation Using Selective Pulse NMR Spectroscopy
One of the most important constituents of olive oil is the secoiridoid polyphenolic derivatives which present an increasing potential for health protection. The European Union legislation based on
Microxine, a new cdc2 kinase inhibitor from the Australian marine sponge Microxina species.
A new purine derivative microxine (1) was isolated from the Australian marine sponge Microxina sp. The compound was isolated via reversed-phase chromatography and its structure determined
Dragmacidin G, a Bioactive Bis-Indole Alkaloid from a Deep-Water Sponge of the Genus Spongosorites
Dragmacidin G shows a broad spectrum of biological activity including inhibition of methicillin-resistant Staphylococcus aureus, Mycobacterium tuberculosis, Plasmodium falciparum, and a panel of pancreatic cancer cell lines.
Bioactive A-type proanthocyanidins from Cinnamomum cassia.
Proanthocyanidins (1-4) possess significant in vitro inhibitory activity against cyclooxygenase-2 (COX-2) at micromolar concentrations.
Application of 1 H-NMR-based metabolomics to the analysis of cranberry (Vaccinium macrocarpon) supplements.
1 H-NMR chemometrics found significant variation in composition of characteristic cranberry metabolites among commercial preparations, reinforcing the need for reliable industry standards.
A new prenylated isoflavone and long chain esters from two Erythrina species.
Two new compounds, a long chain ester 1 of p-coumaric acid and a prenylated isoflavone, senegalensin [5], 5,4'-dihydroxy-8-(gamma,gamma-dimethylallyl)-[5"-(hydroxyisopropyl ) (2",3":6.7)] isoflavone,
Arabinoxyloglucan Oligosaccharides May Contribute to the Antiadhesive Properties of Porcine Urine after Cranberry Consumption.
Results indicate that oligosaccharides structurally related to those found in cranberry may contribute to the antiadhesion properties of urine after cranberry consumption.
Three new peroxides from the sponge Plakinastrella species.
Two new five-membered-ring peroxide acids, plakinic acid F (3) and epiplakinic acid F (4), and a new peroxide−lactone, plakortolide F (5), were isolated from a sponge of the genus Plakinastrella
Distinguishing Vaccinium species by chemical fingerprinting based on NMR spectra, validated with spectra collected in different laboratories.
Spectra acquired on different spectrometers at different sites classifed into the expected group for the Vaccinium spp.
