Chinese green teas are mainly made of the leaves of the plant Camellia sinensis and mainly distributed in provinces of Zhejiang, Anhui, Henan and Jiangsu, etc. Because of having same tea varieties and processing technology, different origins of green teas are very similar in appearance. Whereas different production areas and climatic conditions between them may have cause different quality characters, such as aroma and taste. So it is very necessary to study the different regions of green teas and explore environment and geographical factors to volatile components influence. In this study, the aroma components of four typical green teas: Xihulongjing, Xinyangmaojian, Lu’anguapian and Biluochun, from Zhejiang, Henan, Anhui and Jiangsu in China, were extracted by Simultaneous Distillation Extraction (SDE) and identified by Gas Chromatography-Mass Spectrometry (GC-MS), then compared the similarities and differences between them on the aroma components was made. The result showed that 61 aroma constituents were indentified in four green teas, mainly including alcohols, hydrocarbons and ketones compounds. Through contrast and comparison of results, we find that these different origins of green teas have some differences, but also share some similarities based on the volatile components. The difference of place of origin and elevation will grow different tea plants and will have different volatile components due to the environment.
