Abstract
The difference of volatile component in Tieguanyin (from Fujian province) and Dongding oolong tea (from Taiwan province) in China was studied by simultaneous steam distillation extraction coupled with gas chromatography-mass spectrometry (GC-MS). A total of 84 volatile compounds were identified in these two kinds of oolong teas and mainly including alcohols, hydrocarbons, aldehydes, ketones and esters compounds, etc. Among them, alcohols are the most abundant components in Tieguanyin and Dongding oolong teas, also includes phytol, nerolidol, linalool, etc. In addition, nitrogens (viz., indole and pyrazines compounds) existed in higher concentration in Dongding oolong tea. The SDE/GC-MS is proven to be a suitable technique to extract and analyze the volatile components of oolong tea. In comparison, there were remarkable differences in flavor and aroma composition of the two types of oolong tea, were helpful for distinguishing these two oolong teas with similar appearance and quality characteristics.
