目的 研究典型食用菊怀珍珠菊Chrysanthemum morifolium与典型药用菊野菊花C. indicum的差异性成分。方法 采用UPLC/Q-TOF-MS结合非靶向代谢组学方法，筛选怀珍珠菊与野菊花的差异性成分。结果 从怀珍珠菊中共鉴定出包括黄酮类、萜类、苯丙素类、有机酸类等类化合物在内的80个代谢产物，其中木犀草苷、艾黄素、秦皮乙素等19个代谢产物是与野菊花具有显著差异性的分子。结论 萜类化合物为怀珍珠菊和野菊花的主要差异性代谢物，这些代谢物与抗炎、抑菌和抗虫害密切相关，值得进一步研究。

Objective To study the differential components of typical edible chrysanthemum ‘HZZJ’ (Chrysanthemum morifolium) and typical medicinal chrysanthemum ‘YJH’ (C. indicum). Methods The differential components of ‘HZZJ’ and ‘YJH’ are screened by UPLC/Q-TOF-MS combined with non-target metabolomics method. Results A total of 80 metabolites including flavonoids, terpenoids, phenylpropanoids, organic acids and other compounds are identified in this study, of which 19, such as luteolin, artemisetin and aesculetin, are molecules with significant differences from wild chrysanthemums. Conclusion Terpenoids are the main differential metabolites of ‘HZZJ’ and ‘YJH’, and these metabolites are closely related to anti-inflammatory, bacteriostatic and pest resistance, and deserve further study.
