Chinese yam ( Thunb. cv. Tiegun), a type of homologous medicinal plant, mainly grows in sandy soil (SCY) and loessial soil (LCY). However, the effects of the soil on the metabolites in SCY and LCY remain unclear. Herein, this study aims to comprehensively elucidate the metabolites in SCY and LCY. A UPLC-MS/MS-based, widely targeted metabolomics approach was adapted to compare the chemical composition of SCY and LCY. A total of 988 metabolites were detected, including 443 primary metabolites, 510 secondary metabolites, and 35 other compounds. Notably, 177 differential metabolites (classified into 12 categories) were identified between SCY and LCY; among them, 85.9% (152 differential metabolites) were upregulated in LCY. LCY significantly increased the contents of primary metabolites such as 38 lipids and 6 nucleotides and derivatives, as well as some secondary metabolites such as 36 flavonoids, 28 phenolic acids, 13 alkaloids, and 6 tannins. The results indicate that loessial soil can improve the nutritional and medicinal value of .
山药（Thunb. cv. Tiegun），一种同源药用植物，主要生长在沙壤土（SCY）和黄土土壤（LCY）中。然而，土壤对 SCY 和 LCY 中代谢物的影响尚不清楚。本研究旨在全面阐明 SCY 和 LCY 中的代谢物。采用基于 UPLC-MS/MS 的广泛靶向代谢组学方法比较 SCY 和 LCY 的化学成分。共检测到 988 种代谢物，包括 443 种初级代谢物、510 种次级代谢物和 35 种其他化合物。值得注意的是，在 SCY 和 LCY 之间鉴定出 177 种差异代谢物（分为 12 类）；其中，LCY 上调 85.9%（152 种差异代谢物）。LCY 显著增加了初级代谢物如 38 种脂质和 6 种核苷酸及其衍生物，以及一些次级代谢物如 36 种类黄酮、28 种酚酸、13 种生物碱和 6 种单宁的含量。结果表明，黄土土壤可以提高山药的营养价值和药用价值。
