Despite their structural similarities, they exhibit distinct biological activities. AS is known for its anti\u2010inflammatory properties and its effectiveness in treating rheumatoid arthritis, while MS is recognized for its ability to promote wound healing and significantly improve burn scars. Additionally, AS is widely utilized in the cosmetics industry due to its antioxidant and moisturizing properties. Currently, separating and purifying these two compounds simultaneously using existing methods is challenging. This study focuses on synthesizing molecularly imprinted polymers (MIPs) through precipitation polymerization with AS as the template. By optimizing various preparation parameters, such as the molar ratios of functional monomers, porogens, and cross\u2010linking agents, high selectivity was achieved. The maximum adsorption capacity reached 19.16\u00a0mg\/g, with an imprinting factor of 2.86. The MIPs were characterized using techniques like scanning electron microscopy (SEM), TA, Brunauer\u2013Emmett\u2013Teller (BET) adsorption, and Fourier\u2010transform infrared (FT\u2010IR). Their effectiveness was assessed through static and dynamic adsorption, desorption, and reusability tests.

These findings indicate that the preparation of MIPs is cost\u2010effective, highly selective, reproducible, and user\u2010friendly, making it a promising method for enriching and isolating AS from complex mixtures.\n                  <\/jats:p>","DOI":"10.1002\/jssc.70128","type":"journal-article","created":{"date-parts":[[2025,4,10]],"date-time":"2025-04-10T00:20:36Z","timestamp":1744244436000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Synthesis and Characterization of Molecularly Imprinted Polymers for the Selective Extraction of Triterpenoid Saponin From\n                    <i>Centella asiatica<\/i>\n                    Crude Extracts"],"prefix":"10.1002","volume":"48","author":[{"given":"Yongxian","family":"Fan","sequence":"first","affiliation":[{"name":"College of Chemical Engineering Zhejiang University of Technology  Hangzhou P.
