不同贮藏年份新会陈皮中挥发性成分含量变化

Content Variation of Volatile Components in Xinhui Citrus Reticulate ‘Chachi'of Different Storage Time

目的:分析不同贮藏年份新会陈皮中挥发性成分的组成和含量,考察贮藏时间对新会陈皮中挥发性成分的影响。方法:采用GC-MS法测定了1983-2012年22批不同贮藏年份的新会陈皮样品,运用函数拟合方法对所得数据与年份的相关性进行了统计分析。结果:除2-甲氨基-苯甲酸甲酯外,其他主要挥发油成分的含量未随贮藏年份增加而呈现下降趋势。β-月桂烯与2-甲氨基-苯甲酸甲酯峰的含量比值与贮藏年份的对数函数相关性达到0.86以上。结论:陈皮"陈久者良"的说法难以用其中挥发性成分含量变化来佐证,但是新会陈皮中β-月桂烯峰与2-甲氨基-苯甲酸甲酯含量比值对陈皮年份鉴别有参考意义,有助于完善广陈皮的质量控制。

Objective：To analyze the composition and content of volatile components of Xinhui Pericarpium Citri Reticulate （PCR） of different storage time.Investigate the influence of storage time on the volatile components.Method：Twenty-two samples of different storage time （from 1983 to 2012） were analyzed by GC-MS.The correlation of the data and the storage time was studied through statistical analysis by function fiftting method.Result：The contents of the major components did not decrease dramatically with the storage time except 2-methylamino-benzoic acid methyl ester.It was found that the content ratio ofβ-myrcene to 2-methylaminobenzoic acid methyl ester changed logarithmically with the storage time.The correlation could reach more than 0.86.Conclusion：It was able to confirm that ‘ longer storage time the better’ for the PCR with the change of the contents of volatile components.However the content ratio ofβ-myrcene to 2-methylamino-benzoic acid methyl ester supply evidence for the identification of storage time of Xinhui PCR,and will improve the quality control of Xinhui PCR.
