This study utilized ultra-performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) to rapidly analyze and identify the chemical constituents in five processed products of Strychni Semen(raw, sand-roasted, fried, urine-soaked, and vinegar-processed products). Using PeakView software to extract compound information, 50 chemical components were identified based on retention time, accurate molecular ion peaks, secondary mass spectrometry data, and comparison with reference standards and relevant literature. Specifically, 41 components were identified in raw Strychni Semen, 48 in sand-roasted, 43 in fried, 41 in urine-soaked, and 40 in vinegar-processed products.

- The study examines the pharmacological effects of volatile components from Atractylodis Rhizoma and how processing affects these components, particularly in terms of reducing dryness and increasing efficacy.
- Using HS-GC-MS technology, the researchers identified a total of 87 volatile components across various processed forms of Atractylodis Rhizoma, revealing significant differences in composition based on processing methods.
- The analysis highlighted 28 key components that showed significant changes post-processing, with 11 specific volatile compounds, such as α-pinene and D-limonene, increasing notably after treatment.
