To analyze components of Citrus reticulata and salt-processed C. reticulata by ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF/MS), and compared the changes in components before and after being processed with salt. Principal component analysis (PCA) and partial least squares discriminant analysis (OPLS-DA) were adopted to analyze the difference in fingerprint between crude and processed C. reticulata, showing increased content of eriocitrin, limonin, nomilin and obacunone increase in salt-processed C. reticulata. Potential chemical markers were identified as limonin, obacunone and nomilin, which could be used for distinguishing index components of crude and processed C. reticulata.
采用超高效液相色谱-四极杆-飞行时间质谱联用技术（UPLC-Q-TOF/MS）分析陈皮及其盐制品的成分，并比较盐制前后成分的变化。采用主成分分析（PCA）和偏最小二乘判别分析（OPLS-DA）分析陈皮生品和炮制品指纹图谱的差异，结果表明盐制陈皮中橙皮苷、柠檬苦素、诺米林和奥巴昆酮的含量增加。确定潜在的化学标志物为柠檬苦素、奥巴昆酮和诺米林，可作为区分陈皮生品和炮制品指标成分的依据。
