摘要： Jinmudan (JM) tea, produced using Camellia sinensis, cultivar JM, is popular among consumers because of its strong floral and fruity aroma. Aroma profiles of white, green, black, and oolong teas, which were obtained from JM and Tanyangcaicha (TY, control and indigenous variety), were investigated. Sensory evaluation was used to describe the quality characteristics of the tea samples. A combination of headspace solid-phase microextraction, gas chromatography-mass spectrometry (HS-SPME/GC-MS), and chemometrics was used to extract and analyze the volatiles in the samples; 162 volatiles were identified and categorized on the basis of their chemical structures. The proportions of chemical categories differed among the teas. The same type of tea obtained from JM and TY differed significantly in concentrations and categories of volatiles. This study will improve our understanding of the profile of volatile compounds in JM teas and create a basis for investigating the biological characteristics of JM teas.
