摘要/Abstract

摘要： 茶叶品质难辨易形成混乱的市场局面,制约了茶产业现代化发展进程。近年来,指纹图谱技术在茶叶感官品评、质量控制和产地判别等方面的应用越来越多,为茶叶的品质鉴定提供了有效的技术支撑。文章就茶叶指纹图谱技术方法进行了综述,包括气相色谱（GC）、高效液相色谱（HPLC）、毛细管电泳（CE）、红外（IR）及近红外光谱（NIR）、核磁共振（NMR）等,并对指纹图谱技术在茶叶应用上存在的问题进行了分析,对其今后的发展做出了展望,为指纹图谱技术在茶叶上的进一步应用提供理论基础和参考依据。

Abstract: Chaotic market situation was formed for identifying the quality of tea difficultly, which affected the modern development of tea industry.In recent years, more and more application to sensory evaluation, quality control and geographical origin determination of tea was studied by fingerprinting techniques, which provides effective technical support for the identification of the quality of tea. The methods of fingerprint technique were reviewed in this paper, including fingerprintings based on gas chromatography(GC), liquid chromatography(LC), capillary electrophoresis (CE), infrared （IR）and near-infrared （NIR）spectroscopy, nuclear magnetic resonance (NMR), etc. The problem of the fingerprint in tea applications were analyzed, and the development in tea was predicted in the paper, The article also gives a theoretical basis and reference for further studies of the fingerprint in tea.

Key words: tea, fingerprinting, gas chromatography, liquid chromatography, nuclear magnetic resonance, spectroscopy
