［Objectives］ To investigate the content and distribution of inorganic elements in Astragalus membranaceus sourced from various regions in Gansu Province. [Methods] 28 batches of A. membranaceus samples were collected and subsequently digested using the Multiwave 7000 super microwave digestion system. The contents of aluminum (Al), barium (Ba), beryllium (Be), cobalt (Co), chromium (Cr), iron (Fe), gallium (Ga), magnesium (Mg), manganese (Mn), nickel (Ni), antimony (Sb), tin (Sn), strontium (Sr), titanium (Ti), thallium (Tl), vanadium (V), and zinc (Zn) were quantified utilizing a PerkinElmer 2000 inductively coupled plasma mass spectrometer. Principal component analysis was performed utilizing SPSS 25.0 to identify the distinctive characteristic elements of A. membranaceus. Additionally, systematic cluster analysis was conducted using these characteristic elements as variables to investigate the relationship between the primary inorganic elements and the geographical origin of A. membranaceus. [Results] 17 inorganic elements were identified in A. membranaceus specimens collected from Gansu Province, with characteristic elements including Ba, Co, Fe, Ga, Mn, Zn, and Sn. The contents of inorganic elements in various sources of A. membranaceus exhibited significant variability and demonstrated distinct clustering characteristics. [Conclusions] A. membranaceus, originating from Gansu Province, exhibits a high content of inorganic elements. However, variations in ecological environments can lead to differences in the specific inorganic elements that are enriched. This study aims to provide a reference for the further development and application of A. membranaceus. |
