Abstract
- An oleanolic acid (OA) surface molecularly imprinted polymer silylated porous composite aerogels (OA-MIP@Si-PC-aerogels) adsorbent material was successfully prepared and characterized. The material not only has a great selectivity for the target molecule OA but also has other noteworthy qualities including high stability, excellent repeatability, and a sizable adsorption capacity. via cellulose and sodium alginate as the main materials, the carrier Si-PC-aerogels were made through ionic cross-linking, chemical cross-linking, and silylation procedures. By adopting a surface molecular imprinting approach on Si-PC-aerogels, OA-MIP@Si-PC-aerogels were effectively created utilizing OA as the template molecule and MAA as the functional monomer. Due to the presence of a specific imprinted layer on the aerogel surface, the adsorption capacity of OA-MIP@Si-PC-aerogels for OA could reach 66.20 mg g−1. OA-MIP@Si-PC-aerogels could achieve a 68.86% yield of OA from the extracts of lingonberry (Vaccinium Vitis-Idaea L.). The adsorption capacity remained at 90% after five consecutive adsorption-desorption cycles. HepG2 cells were exposed to OA that was effectively enriched with OA-MIP@Si-PC-aerogels in lingonberry (Vaccinium Vitis-Idaea L.) fruit homogenates. This OA significantly inhibited the growth of HepG2 cells in vitro. It further demonstrated that OA-MIP@Si-PC-aerogels could efficiently target OA enrichment and separation with good recovery. [Display omitted] • Silanized porous composite aerogel (Si-PC-aerogels) were preparaed successfully. • OA-MIP@Si-PC-aerogels with stable recyclability is green, economic and low-toxic. • Application of OA-MIP@Si-PC-aerogels in efficient targeted extraction of oleanolic acid. • Oleanolic acid extracted from OA-MIP@Si-PC-aerogels inhibits the growth of HepG2 cells.
