To evaluate the quality of Cyclocarya paliurus (Batal) Ijinskaja tea, main chemical compounds, agricultural chemicals residues, and aroma compounds of Cyclocarya paliurus tea were analyzed. The aroma compounds of Cyclocarya paliurus tea were extracted by headspace solid-phase microextraction (HS—SPME), and analyzed by gas chromatography-mass spectrometry (GC—MS). The results showed that the contents of total flavonoids, polysaccharide, triterpene saponinsin of Cyclocarya paliurus tea were 0.73%, 2.53% and 0.88%, respectively. As for pesticide residues in Cyclocarya paliurus tea, 23 kinds of pesticide residues are below the limit of detection. The content of lead, arsenic, and mercury in Cyclocarya paliurus tea were 2.27, 0.38, 0.058 mg/kg respectively, which all meet the requirements of the State standards. Thirty kinds of aromatic compounds of were identified from Cyclocarya paliurus tea, which contribute to a complex green grass, floral, fruity and woody scent. The highest content components was benzyl alcohol (13.50%), the second was 2- methyl-2-butene aldehyde (13.10%).
