Use of Serially Coupled Capillary Columns with Different Polarity of Stationary Phases for the Separation of the Natural Complex Volatile Mixture of the Marine Red Alga Corallina elongata

摘要

Separation of a complex of natural volatile compounds using serially coupled capillary columns with different polarity of stationary phases by gas chromatography-mass spectrometry from the medicinal marine red alga Corallina elon-gata is reported. Nearly 200 hydrocarbons, halogen compounds, fatty acids, and other metabolites were found. Using this gas chromatography procedure we demonstrate the successful separation of different volatile organic compounds.
