[Abstract]
Volatile components in mulberry leaf tea were extracted by headspace solid phase micro extraction method using gas chromatography-mass spectrometry (GC-MS) technique. NIST 05 spectrum-search showed that 42 volatile compounds existed in mulberry leaf tea, including 10 aldehydes, 9 ketones 4 alcohols, 3 esters, 2 acides, 10 alkanes and 4 other compounds. Among the volatile compounds, aldehydes and ketones showed high contents, being of 24.67% and 22.36%, respectively.
