    Notes: Summary Two phenylpropanoid compounds, 2-allyl-4,5-dimethoxyphenol(II) and coniferyl alcohol(III), were characterized from body tissue of wild males of the Oriental fruit fly,Dacus dorsalis. These compounds accumulated in the rectal glands only when laboratory-reared males were fed with methyl eugenol. Compound II was released into the air during dusk, which coincides with the fly courtship period. Pheromonal and allomonal effects of the phenylpropanoids were examined.

    PVT and derived thermodynamic properties for the glycine-water system at temperatures from 298 to 323 K and pressures up to 300 MPa (1989)

    Notes: Abstract The specific volumes for the glycine-water system have been measured in the temperature range 298–323 K and at pressures up to 300 MPa, using a glass piezometer. The uncertainties in the specific volume are estimated to be less than 0.03%. The PVT relations are correlated by the Tait equation. Good agreement was found with correlations by the Tait equation using a simple extension similar to that proposed by Dymond and Malhotra. The isothermal compressibility and apparent molar volume of glycine are calculated by the Tait equation. The apparent molar volume of glycine increases with increasing pressure.

    Application of high-performance liquid chromatography/atmospheric pressure ionization mass spectrometry for the analysis of non-volatile compounds (1988)
    Chichester : Wiley-Blackwell
    Biological Mass Spectrometry 16 (1988), S. 331-334

    Notes: The combination of a high-performance liquid chromatograph and a magnetic type mass spectrometer with an atmospheric ionization source has been applied for analyses of thermolabile compounds, i.e. antibiotics, amino acids and glycosphingolipids.Chromatography was performed on a 4 mm i.d. x 150 mm column packed with 5 μm ODS at a flow rate of 1 ml min-1. The liquid chromatography/atmospheric pressure ionization (LC/API) magnetic-type mass spectrometer provides not only an abundant pseudo-molecular ion but also fragment ions which give a structural information resulting from collision-induced dissociation at the differential pumping region of the liquid chromatograph/mass spectrometer interface. The isomers of kanamycins could be differentiated from each other on the basis of their mass spectra obtained at the relatively higher drift voltage applied. LC/API mass spectra of leucine and isoleucine were very similar, but it was easy to differentiate one from another by checking the existence of the ions at m/z 43 or m/z 57 in their mass spectra. The LC/API mass spectra of glucosylceramides showed [MH]+ ions of good abundance and significant fragment ions useful for chemical characterization at a proper drift voltage setting in a controlled and reproducible manner.
