摘要: 采用HPLC分析技术系统研究了国内茶树种质资源的GCG含量、GCG在绿茶加工过程中的变化以及高温蒸汽处理对绿茶中GCG含量的影响。结果表明,在200份茶树种质中发现GCG的含量大于1.5%的茶树种质有5个;绿茶加工过程中GCG含量有持续增加的趋势,温度是影响茶叶GCG含量的关键因素;茶鲜叶经过高温蒸汽处理,能有效提高绿茶中的GCG含量。

Abstract: The GCG content in different tea germplasms, change of GCG content during green tea processing and the tea leaf treated with high temperature steam were studied by using the HPLC determination. Results showed that the content of GCG in five tested tea cultivars was more than 1.5% among 200 tea germplasms, and it was increased continuously during the green tea processing. Temperature was the key factor that influenced the GCG content in tea, and the high temperature steam treatment could effectively increase the GCG content in green tea.

Key words: tea, GCG, high temperature steam
