摘要： This study investigates the compositional characteristics and quantitative differences of ginsenosides across various ginseng tissues, with a particular focus on the specific accumulation patterns of malonyl ginsenosides. Five tissue samples-ginseng fruit (F), leaf (L), taproot (TR), lateral root (LR), and fibrous root (FR)-were analyzed using Orbitrap Fusion high-resolution liquid chromatography-mass spectrometry. A total of 413 ginsenosides, including 33 standards, were identified, encompassing 172 protopanaxadiol (PPD)-type, 188 protopanaxatriol (PPT)-type, 14 oleanolic acid (OA)-type, and 12 ocotillol (OT)-type ginsenosides, of which 160 were malonyl ginsenosides. Statistical analysis revealed significant variations in the relative content per unit mass of malonyl ginsenosides across tissues, with the highest levels in fibrous roots, followed by fruits, lateral roots, leaves, and taproots. Distinct tissue-specific differences in malonyl ginsenoside types and quantities were observed: fruits exhibited 51 malonyl ginsenosides with significantly higher levels, compared to 8, 14, and 17 in lateral roots, fibrous roots, and leaves, whereas TR showed no significant enrichment. This study elucidates the diversity and unique distribution of malonyl ginsenosides in ginseng roots, leaves, and fruits, providing a valuable basis for the targeted selection of tissues with high malonyl ginsenoside content and the development of functional food and medicinal products.
