Determining Composition of Volatiles in Couroupita guianensis Aubl. Through Headspace-Solid Phase Micro-Extraction (HS-SPME)

Composition of volatile components in Couroupita guianensis Aubl. flowers was analyzed using headspace-solid phase micro-extraction (HS-SPME), followed by capillary gas chromatography and mass spectrometry (GC-MS) separation and identification. In all, 75 compounds were identified accounting for 96....
