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

摘要:

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。

Abstract:

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 of β-myrcene to 2-methylamino-benzoic 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 of β-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.
