Glands of workers ofT. caespitum contain, on average, 70 ng of oil containing C13 to C17 linear hydrocarbons withn-pentadecane (64%) and a mixture of pentadecenes (14%) as major components.T. impurum glands are smaller and contain an average of 40 ng of the same mixture but withn-pentadecane (49%) and a sesquiterpenoid compound (19%) the major components. Two isomeric pentadecenes, (Z)-6-pentadecene and (Z)-7-pentadecene are present in both species.T. semilaeve workers contain on average only 30 ng of a simple mixture of hydrocarbons with pentadecane contributing more than 90% of the total.Type of Medium: Electronic ResourceURL: -

As a result of their superior peak shape (comparable ton-alkanes of similar retention times) and relatively low Kovat's retention indices (3300–3900), the bis(trialkylsiloxy)Si(IV) derivatives offer the greatest potential for the GC analysis of geological mixtures of alkyl porphyrins. Similar derivatives of porphyrins of biomedical importance, possessing polar side chains, are also amenable to GC and GC-MS analysis.Type of Medium: Electronic ResourceURL: -

A significant hypsochromic shift in the visible (1Bu+) λmax of β-carotene (β,β-carotene), lycopene (ψ,ψ-carotene), zeaxanthin (β,β-carotene-3,3′-diol), canthaxanthin (β,β-carotene-4,4′-dione) and astaxanthin (3,3′-dihydroxy-β,β-carotene-4,4′-dione) in supercritical CO2 was observed in comparison to that in hexane. In addition, the effects of variations in pressure (1500–6000 psi) and temperature (35–50 °C) on the wavelength shift of all-trans-β-carotene have been assessed. Parallel studies were also performed on 15-cis-β-carotene, and a similar hypsochromic shift in the main, visible, λmax was observed. Thecis-peak (1Ag+) of this carotenoid also exhibited a significant, but smaller, hypsochromic shift in comparison to that measured in hexane. However, in contrast to the behaviour of the visible maxima, subsequent alterations to both the pressure and temperature of supercritical CO2 did not further alter the λmax of thecis-peak of 15-cis-β-carotene.Type of Medium: Electronic ResourceURL: -

The technique is compatible with combined high-temperature gas chromatography/mass spectrometry and it has a potentially wide application.Additional Material: 5 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 1052-9306Keywords: Chemistry ; Analytical Chemistry and SpectroscopySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: Synthetic long-chain fatty acyl esters of pregnenolone and 3β-hydroxy-5α-pregnan-20-one (5α-pregnanolone) were submitted to gas chromatography (GC) and GC/mass spectrometry (GC/MS). Analyses were readily performed using short (8-12 m) flexible fused-silica capillary columns coated with thin films of immobilized apolar stationary phase (e.g. OV-1 type). The electron impact (EI) mass spectra were found to be of limited value for structure investigations, as molecular ions (M+.) were either weak or absent. EI spectra also lacked characteristic fatty acyl fragment ions. In contrast, negative ion ammonia chemical ionization produced characteristic [M — H]- ions and diagnostic fragment ions. The application of the above methods to biochemical investigations is exemplified by GC/MS analysis of the steroidal fatty acyl esters in extracts of bovine adrenal tissue, and the metabolites produced by incubating starfish (Asterias rubens) testicular tissue with exogenous progesterone.Additional Material: 4 Ill.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1052-9306Keywords: Chemistry ; Analytical Chemistry and SpectroscopySource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyNotes: A stable isotope dilution assay has been developed for the quantitative determination of cholesterol sulphate in plasma using negative ion fast atom bomardment (FAB) mass spectrometry. The assay is highly selective and avoids problems of contamination from free cholesterol and other conjugates of cholesterol present in plasma. (6,7,7-2H3)Cholesterol sulphate is used as the internal standard and solvent extraction and silica Sep-Paks are employed to isolate plasma cholesterol sulphate. Limited-range acceleration voltage scanning in FAB mass spectrometric analyses leads to sub-microgram detection limits. Comparison of results obtained by FAB mass spectrometry of the intact cholesterol sulphate, and by gas chromatography/mass spectrometry selected ion monitoring of the free cholesterol, released by solvolysis of the cholesterol sulphate, showed that the latter approach probably overestimates plasma levels of cholesterol sulphate.Additional Material: 4 Ill.Type of Medium: Electronic ResourceURL:
