Avian exocrine secretions. I : chemical characterization of the volatile action of the uropygial secretion of the green woodhoopoe, Phoeniculus purpureus

Burger, B. V.; Reiter, B.; Borzyk, O.; Du Plessis, M. A. (Springer Verlag, 2004-08)

Using gas chromatography–mass spectrometry in conjunction with auxiliary techniques such as solid phase microextraction and determination of double bond positions by means of dimethyl disulfide derivatization, 45 ...

Thermal modulator array for analyte modulation and comprehensive two-dimensional gas chromatography

Burger, B. V.; Snyman, Tertia; Burger, Wina J. G.; Van Rooyen, Willie F. (Wiley-VCH Verlag, 2003-01)

Segmented thermal modulators were fabricated for the modulation of column effluent in one-dimensional gas chromatography, comprehensive two-dimensional gas chromatography, and as sample introduction devices in other ...

Semiochemicals of the Scarabaeinae VII : identification and synthesis of EAD-active constituents of abdominal sex attracting secretion of the male dung beetle Kheper subaeneus

Burger, B. V.; Petersen, W. G. B.; Weber, W. G.; Munro, Z. M. (Springer Verlag, 2002-12)

Using gas chromatography with flame ionization detection (FID) and electroantennographic detection (EAD) in parallel, butanoic acid, skatole, and (E)-2,6-dimethyl-6-octen-2-ol were identified as constituents of the abdominal ...

Mammalian exocrine secretions XV. Constituents of secretion of ventral gland of male dwarf hamster, Phodopus sungorus sungorus

Burger, B. V.; Smit, D.; Spies, H. S. C.; Schmidt, C.; Schmidt, U.; Telitsina, A. Y.; Grierson, G. R. (Springer Verlag, 2001-06)

In a study aimed at the chemical characterization of constituents of the ventral gland secretion of the male dwarf hamster, Phodopus sungorus sungorus, 48 compounds, including saturated alcohols, saturated and unsaturated ...

Lizard epidermal gland secretions I : chemical characterization of the femoral gland secretion of the sungazer, Cordylus giganteus

Louw, Stefan; Burger, B. V.; Le Roux, Maritha; Van Wyk, Johannes H. (Springer Verlag, 2007-09)

The giant girdled lizard or sungazer, Cordylus giganteus, is endemic to South Africa. It has been suggested that in this species, as in other lizard species, epidermal glands in the femoral, pre-cloacal regions, and cloacal ...

Semiochemicals of the Scarabaeinae, III : identification of the attractant for the dung beetle Pachylomerus femoralis in the fruit of the Spineless monkey orange tree, Strychnos madagascariensis

Burger, B. V.; Petersen, W. G. B. (Dieterich'sche Verlagsbuchhandlung, Wiesbaden (now Mainz), 1991-04)

Following the observation that the non-ball-rolling dung beetle Pachylomerus femoralis (Kirby) rolled the flesh-covered seeds from the fruit of the spineless monkey orange tree, Strychnos madagascariensis Poiret, an ...

Development of second-generation sample enrichment probe for improved sorptive analysis of volatile organic compounds

Burger, B. V.; Le Roux, M.; Marx, B.; Herbert, S. A.; Amakali, K. T. (Elsevier, 2011-03)

The sample enrichment probe (SEP) has recently been introduced as a user-friendly and cost-effective method for the sorptive extraction of volatile organic analytes from gaseous and aqueous samples for GC and GC-MS analyses. ...

Formation of a seed germination promoter from carbohydrates and amino acids

Light, Marnie E.; Burger, B. V.; Van Staden, Johannes (American Chemical Society, 2005-07)

The ability of plant-derived smoke to act as a germination cue in many species has led to widespread interest in this aspect of seed biology. Recently, 3-methyl-2H-furo[2,3-c]pyran-2-one was identified as the main germination ...

Semiochemicals of the scarabaeinae: VI. Identification of EAD-active constituents of abdominal secretion of male dung beetle, Kheper nigroaeneus

Burger, B. V.; Petersen, W. G. B. (Springer Verlag, 2002-03)

Using gas chromatography with flame ionization detection (FID) anal electroantennographic detection (EAD) in parallel, and employing chiral and achiral capillary columns, three constituents of the abdominal sex-attracting ...
