Abstract:

This study aimed to identify and quantify the aroma components of Lu’an Guapian, one of China’s top ten famous
teas, by simultaneous distillated extraction (SDE) and gas chromatography-mass spectrometry (GC-MS). The results showed
that the aroma components of Lu’an Guapian were relatively stable over a storage period of 12 months and its main aroma
compounds were similar at different quality grades and the aroma composition of Lu’an Guapian differed obviously from
that of other well-known teas. The obtained data showed that the aroma components of Lu’an Guapian were stable and
different obviously from those of other teas, and that GC-MS was useful to detect the aroma components of Lu’an Guapian
for quality control purpose.
