A new solution for an old problem: the regiochemical distribution of the acyl chains in galactolipids can be established by electrospray ionization tandem mass spectrometry.
TLDR
Electrospray ionization-quadrupole ion trap mass spectrometry (ESI-QITMS), either in positive- or in negative-ion mode, has been used to establish the chemical structures of the fatty acids attached to the primary and secondary hydroxyl groups of the glycerol moiety of natural monogalactosyl- (MGDG) and DGDG mixtures.

Pyrolysis of cellulose catalysed by nanopowder metal oxides: production and characterisation of a chiral hydroxylactone and its role as building block
As a bulk component of plant biomass, cellulose plays a key role in the route leading to viable chemicals from renewable resources. Pyrolysis is a thermal treatment that converts cellulose into a… Expand
Characterization of anticholinesterase-active 3-alkylpyridinium polymers from the marine sponge Reniera sarai in aqueous solutions.
TLDR
It is found that biologically active polymers are composed of head-to-tail 3-alkylpyridinium units, which are soluble only in water, while low molecular oligomers are readily soluble in organic solvents. Expand
Discorhabdin alkaloids from Antarctic Latrunculia spp. sponges as a new class of cholinesterase inhibitors.
TLDR
Findings are promising for development of cholinesterase inhibitors based on the scaffold of discorhabdins, as potential new agents for treatment of patients with Alzheimer's disease. Expand
Aplysinopsin-type alkaloids from Dendrophyllia sp., a scleractinian coral of the family dendrophylliidae of the philippines, facile photochemical (Z/E) photoisomerization and thermal reversal
The dendrophylliid Dendrophyllia sp. of Palawan contains the indole alkaloids 2′-demethylaplysinopsin (4) and 2′-demethyl-3′-N-methylaplysinopsin (6) and their 6-bromo analogues in H (Z/E) ratio… Expand
Novel Aplysinopsin‐Type Alkaloids from Scleractinian Corals of the Family Dendrophylliidae of the Mediterranean and the Philippines. Configurational‐assignment criteria, stereospecific synthesis, and…
From the scleractinian coral Tubastraea sp. (Dendrophylliidae) collected at Palawan, Philippines, 3′-deimino-3′-oxoaplysinopsin (4) and 6-bromo-3′-deimino-3′-oxoaplysinopsin (6) are now isolated as… Expand
A new method for the identification and the structural characterisation of carotenoid esters in freshwater microorganisms by liquid chromatography/electrospray ionisation tandem mass spectrometry.
Liquid chromatography/electrospray ionisation mass spectrometry (LC/ESI-MS) has been employed to identify carotenoid esters present in raw organic extracts of pigmented freshwater microalgae and to… Expand
On-line identification of secondary metabolites in freshwater microalgae and cyanobacteria by combined liquid chromatography-photodiode array detection-mass spectrometric techniques.
TLDR
It is shown that in the same chromatographic analysis other classes of natural products, such as galactolipids, alkaloids, sterols and mycosporine-like amino acids, can be detected by using combined optical and mass spectrometric techniques. Expand
Fatty acid composition of common barbel (Barbus barbus) roe and evaluation of its haemolytic and cytotoxic activities.
TLDR
The chemical composition of the haemolytically active fraction from methanolic barbel roe extract was analyzed and polyunsaturated fatty acids proved to be the three most abundant members of a complex series of free fatty acids ranging from C14:0 to C24:5. Expand
Novel Naamidine‐Type Alkaloids and Mixed‐Ligand Zinc(II) Complexes from a Calcareous Sponge, Leucetta sp., of the Coral Sea
As compounds from a calcareous sponge, Leucetta sp., of the Coral Sea, we isolated a series of novel naamidine-type alkaloids, 6–10, which are oxidized at a single benzylic position. We also report… Expand
