Analysis of volatile compounds in coriander / Rozita Osman, Associate Prof. Dr Nor'ashikin Saim and Noraini Hamzah

This study focuses on the analysis of volatile compounds in coriander leaves and seeds using solid-phase microextraction (SPME) and subcritical water extraction (SWE). Separation and identification of the compounds were done using gas chromatography with mass spectrometry detector (GC-MSD). Optimiza...
