Abstract:
Xanthoceras sorbifolium seeds have a wide range of applications in the food and pharmaceutical industries. To compare and analyze the chemical compositions of different parts of X. sorbifolium seeds and explore the potential value and research prospects of non-medicinal parts, this study used ultra-high-performance liquid chromatography quadrupole Orbitrap high-resolution mass spectrometry(UHPLC-Q-Orbitrap HRMS) to detect the chemical composition of various parts of the seeds. A total of 82 components were preliminary identified from X. sorbifolium seeds, including 5 amino acids, 4 polyphenols, 3 phenylpropionic acids, 7 organic acids, 15 flavonoids, 6 glycosides, and 23 saponins. Mass spectrometry molecular networking(MN) analysis was conducted on the results from different parts of the seeds, revealing significant differences in the components of the seed kernel, seed coat, and seed shell. The saponins and flavonoids in the seed kernel were superior in terms of variety and content to those in the seed coat and shell. Based on the chromatographic peaks of different parts from multiple batches of samples, multivariate statistical analysis was carried out. Four differential components were determined using HPLC, and the average content of these components in the seed kernel, seed coat, and seed shell were as follows: 0.183 6, 0.887 4, and 1.440 1 mg·g~(-1) for fraxin; 0.035 8, 0.124 1, and 0.044 5 mg·g~(-1) for catechin; 0.032 9, 0.072 0, and 0.221 5 mg·g~(-1) for fraxetin; 0.435 9, 2.114 7, and 0.259 7 mg·g~(-1) for epicatechin. The results showed that catechin and fraxetin had relatively low content in all parts, while fraxin had higher content in the seed coat and seed shell, and epicatechin had higher content in the seed kernel and seed coat. Therefore, the seed coat and seed shell possess certain development value. This study provides rapid analysis and comparison of the chemical compositions of different parts of X. sorbifolium seeds, which offers an experimental basis for the research and clinical application of medicinal substances in X. sorbifolium seeds.
