GC Reveals Neanderthals' Use of Medicinal Plants July 23, 2012 GC Reveals Neanderthals' Use of Medicinal Plants

el-sidron-cave-150px An international team of researchers revealed that Neanderthals from a site in El Sidrón, Spain had considered plants for its medicinal properties. Recently published in the science journal Naturwissenschaften - The Science of Nature, their study used gas chromatography techniques to gain an in-depth look at the Neanderthal diet.  

Led by Karen Hardy, an anthropologist from Universitat Autònoma de Barcelona, the team consisted of researchers from Spain, Australia and the UK. They looked into the diet of five Neanderthals by examining their teeth. To identify the chemical compositions in their teeth, the team used thermal desorption - gas chromatography (TD-GC-MS) and pyrolysis gas-chromatography-mass spectrometry (Py-GC-MS) on 10 dental calculus (calcified dental plaque) samples. The analysis suggested wood-fire smoke, cooked starchy foods, oil shale and bitter tasting plants, namely yarrow and chamomile. The findings also led them to believe that the Neanderthal menu included not only meat but also various plant species.

What intrigued the researchers was the ingestion of bitter tasting plants among these ancient individuals. Stephen Buckley, co-author of the study, said that Neanderthals could discern the bitterness of yarrow and chamomile, and thus, taste value would have not been their basis of such a habit. Hardy hypothesized that the intake of yarrow and chamomile may have been due to the plants' medicinal properties. "All modern higher primates make use of medicinal plants, so perhaps Neanderthals did too," Hardy pointed out. "

The Neanderthal occupants of El Sidrón had a sophisticated knowledge of their natural surroundings which included the ability to select and use certain plants", the team concluded.

The new use of chromatography techniques, including GC has paved the way for researchers to understand how ancient men lived thousands of years ago. It is essential that researchers use only high-quality gas chromatography systems to ensure the accuracy of the resulting data and their analyses.

Liquefied Petroleum Gas (LPG) Analysis with the DANI Master GC December 8, 2011 Liquefied Petroleum Gas (LPG) Analysis with the DANI Master GC Quality control, process monitoring and research purposes drive the need for composition analysis of petrochemicals like liquefied petroleum gas (LPG). Primarily used as fuel for heating, cooking, and even transportation, LPG is obtained through crude oil refining, natural gas processing, and propene mixtures. LPG mainly consists of propane, butane and other C3 and C4 hydrocarbons with both single and double bonds including propylene and butylene.
Monitor Biodiesel Quality with the DANI Master GC December 4, 2011 Monitor Biodiesel Quality with the DANI Master GC As an alternative to petroleum-diesel, biodiesel fuels compression-ignition engines of cars and generators. Sources of this biofuel include extracted oils from palm, canola, rapeseed, soybean, sunflower, and even waste oils from cooking and animal fats.
Effective Natural Gas Analysis with the DANI Master GC November 27, 2011 Effective Natural Gas Analysis with the DANI Master GC Natural gas is used in industrial, commercial and residential applications, including transportation, waste treatment, and general heating and cooling. As the natural gas market surges, close monitoring and assessment of this energy resource is necessary, highlighting the importance of natural gas analysis (NGA).
GC-MS Study Leads to Breast Cancer BioMarker Discovery November 24, 2011 GC-MS Study Leads to Breast Cancer BioMarker Discovery Recently, experts from universities in Harbin, People's Republic of China, conducted a multivariate statistical analysis of gas-chromatograph-mass spectrometry data that led to the discovery of biomarkers for early breast cancer detection.
Fatty Acid Methyl Ester (FAME) Analysis with GC November 29, 1999 Fatty Acid Methyl Ester (FAME) Analysis with GC With an increased interest in studying the health effects of fatty acids, it is essential to understand the different means to analyze them. Fatty acid methyl ester (FAME) is created through an alkali catalyzed reaction between fats or fatty acids and methanol. Fatty acid methyl esters can be analyzed through gas chromatography (GC).
