Volatile Signals During Pregnancy: A Possible Chemical Basis for Mother–Infant Recognition

摘要: Human pheromones play a role in regulating relationships and apparently influence partner choice mother–infant recognition. We analyzed the chemical content of volatiles from sweat patch samples para-axillary nipple–areola regions women during pregnancy after childbirth. Solid phase microextraction was used to extract volatile compounds, which were then characterized quantified by gas chromatography–mass spectrometry. During pregnancy, developed distinctive pattern five compounds common (1-dodecanol, 1-1′-oxybis octane, isocurcumenol, α-hexyl-cinnamic aldehyde, isopropyl myristate). These absent outside had slightly different patterns two body areas. Differentiation among pregnant may help newborns distinguish their own mothers.
