Yam is a versatile economic crop that serves both medicinal and dietary purposes. Dehua County, located in Fujian Province, China, renowned as one of the major yam production areas, with cultivation history spanning over 600 years. It has successfully cultivated Qingfeng Ziyu yam, which have been recognized China's "Geographical Indications for Agricultural Products." However, no comprehensive studies conducted to evaluate their quality. This study meticulously utilized authentic material "Iron yam" benchmark, employing advanced techniques such high-performance liquid chromatography (HPLC), ultraviolet spectrophotometry, flame atomic absorption spectrometry systematically analyze nutritional hypoglycemic active components three distinct varieties. In order interpret data, descriptive statistics, correlation analysis, principal component analysis (PCA), partial least squares discriminant (PLS-DA), cluster multiple linear regression were applied. The results revealed significant variations concentrations various indicators across types. Correlation identified 65 pairs exceptionally strong correlations 39 statistically associations. Additionally, demonstrated Iron exhibited most favorable overall Notably, characterized by its high concentration compounds, emerged promising raw products, showcasing potential this field.
