简介
A supercritical carbon dioxide extraction method to obtain selectively volatile compounds of saffron without sample destruction has been developed. The influence of both pressure and temperature was studied, 20 MPa and 100°C being the best conditions to extract the total safranal content. A decrease in supercritical fluid density was shown to be a critical parameter for enhancing the extraction power of carbon dioxide. For all the assay conditions, the extracts mainly contained safranal and HTCC, as demonstrated by gas chromatography and high-performance liquid chromatography analyses. Both chromatographic methods were suitable for safranal quantification and showed excellent agreement. Supercritical extracts from five different saffron types were studied by high-performance liquid chromatography and their safranal contents were determined.
