Differential Analysis of Non-Volatile and Volatile Organic Compounds in <i>Lonicerae japonicae</i> Flos Across Four Geographical Origins of China Using HS-GC-IMS, HS-SPME-GC-MS, UPLC-Q-TOF-MS, and Multivariate Statistical Methods.

ABSTRACT: Geographical origin constitutes one of the key factors that exert an influence on chemical compounds of Lonicerae japonicae flos (LJF). The present research was designed to explore differences among volatile organic compounds (VOCs) and non-VOCs among LJF samples from four geographical origins. Selection of 32 LJF samples with similar genetic backgrounds was performed using simple sequence repeat markers. Headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) and headspace-gas chromatography-ion mobility spectrometry (HS-GC-IMS) were utilized to analyze VOCs, while non-VOCs were detected via ultra-high-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS). Multivariate statistical analyses were applied to sc
