The chemicals in essential oils from peels of three varieties of Citrus reticulata Blanco like C. kinokuni Tanaka (K), C. reticulata
‘Dahongpao’ (D) and C. reticulata ‘zhang shuensis’ (Z) were investigated by gas chromatography-mass spectrometry (GC-MS) and gas
chromatography-flame ionization detector (GC-FID), respectively. A total of 97 compounds were quantified in which 80 components
were identified and 17 unknown components were detected. The quantitation results of D and Z were profoundly different from
previous studies due to the different treatment to peels. The different oil-types from K, D, and Z were high in β-myrcene, p-cymene,limonene, γ-terpinene, α-terpineol, thymol, (E, E)-α-farnesene, spathulenol and isospathulenol. The chemicals’ fluctuation in oils of
D and Z was more pronounced than that of K. Principal component analysis (PCA) revealed the peel of K, D and Z could be classified
as three kinds according to their chemical changeability, respectively, consisting with the usage of these peels in Chinese medicine.
Lastly, the oils’ chemotypes of K, D, Z and other cultivars were analyzed, showing that the % variation of six characteristic components
including limonene, γ-terpinene, methyl N-methylanthranilate, linalool, (E, E)-α-farnesene, and thymol, played an important role in
discriminating oil-types from varieties of C. reticulata.
