Study on the Chemical Constituents of Different Parts of Xanthoceras sorbifolia Bunge Based on Plant Metabolomics

ABSTRACT Xanthoceras sorbifolia is valued in food, landscape, and medicine, with its husk containing triterpenoid saponin known for anti‐Alzheimer's effects. This study, using ultra‐high‐performance liquid chromatography coupled with high‐resolution mass spectrometry and plant metabolomics, compared the chemical profiles of different parts of X. sorbifolia to assess their potential for replacing the husk in medicinal use. The findings show that only the bark and wood contain small amounts of triterpene and triterpenoids, which cannot substitute the husk's medicinal value. These results support the quality control and clinical application of the husk.
