Spatiotemporal and methodological influences on Astragali Radix active ingredients: a comprehensive study of geographical, aging, cultivation, and sampling factors.

ABSTRACT: Astragali Radix, known as a commonly used traditional Chinese medicine, is highly valued for its diverse pharmacologically active compounds. The concentrations of polysaccharides, saponins, and flavonoids serve as critical determinants of product quality. Emerging evidence underscores the pressing need for systematic analysis to elucidate the influence of price-related factors (including growth areas, years, patterns, collected parts, and sampling modes) on the quality of Astragali Radix. In our study, a total of 115 batch samples were collected and the contents of polysaccharides, saponins and flavonoids were determined by spectrophotometry. Comprehensive statistical analyses were performed by the R programming language for three active ingredients across price-influencing factors, and th
