The flavour of pandan (Pandanus amaryllifolius Roxb.) leaves was extracted by supercritical fluid
with CO2 (SC-CO2) under different conditions of pressure, temperature and contact time to determine the yield of 2-acetyl-1-pyrroline (ACPY) and various other components; 14 volatile compounds on the gas chromatogram were identified, and the predominant constituents were ACPY and 3-methyl-2(5H)-furanone.
