| Abstract: | By extracting the volatile components of Xinyang MaoJian tea with the method of SDE (Simultaneous Distillation and Extraction), analyzing the extracted tea oil by two different polar capillary columns SE-54 and BPX70 with GC-MS. It is found out that the effect of the semi polar capillary column SE-54 is better than high polar column BPX70. With SE-54, 45 aroma constituents of spring tea and 63 aroma constituents of summer tea were analyzed and identified. By comparing the difference between the spring tea and summer tea aroma constituents, it is found out that the aroma quality of the spring tea is much better than that of the summer tea. |
