Membrane-Protected Molecularly Imprinted Polymer for the Microextraction of Indole-3-butyric Acid in Mung Bean Sprouts

Abstract: Based on the hollow fiber protected molecularly imprinted polymer, a micro-solid-phase extraction (μ-SPE) method was developed and applied for the analysis of indole-3-butyric acid in mung bean sprouts by high-performance liquid chromatography. The extraction conditions of the μ-SPE method were optimized using L9(34) orthogonal, and optimum conditions were found as follows: pH of sample solution was 2.0, chloroform was the organic solvent for embedding the μ-SPE bars, and acetonitrile was the desorption solven… Show more

“…The monolithic polymer in hollow fiber was compared with several membrane‐protected adsorbents used to prepare SPE columns, including Waters Oasis HLB, Oasis MCX, DIKMA ProElut PLS, BESEP C18‐H, and Bond Elut PLEXA. Those SPE adsorbents were directly packed into hollow fiber lumen following our reported method . And the results are shown in Figure .…”

“…IBA is an endogenous precursor compound of auxin, which influences plant development through the b-oxidation of the carbon side chain for conversion to IAA (Damodaran & Strader, 2019). Although IBA is detected at low levels compared to IAA, IBA is correlated to adventitious root formation and is more efficient than IAA because of its stability in solution and in cell tissues (Fattorini et al, 2017;Aihebaier et al, 2019). Studies in Arabidopsis thaliana have shown that the enzymatic activity of anthranilate synthase (ASA1I/ASB1) is necessary for the formation of adventitious roots by converting IBA to IAA.…”

“…For instance, IAA and IBA are involved in both coleoptile elongation and lateral root development, while 4-Cl-AA is involved in fruit and seed development in some plant species. In addition, crosstalk between auxin biosynthesis and transport has been Auxins are synthesized and present in all plant parts, with the maximum biosynthesis in the cotyledons, shoots and roots (Aihebaier et al, 2019;Damodaran & Strader, 2019). Because of its importance in tissues that are in the process of cell division and growth, auxin is transported efficiently from where it is synthesized to the site where it is needed (Brumos et al, 2018).…”

“…In this technique, the adsorbent or an acceptor liquid phase is held in the membrane so that target species penetrate easily over the membrane pores and are retained by the solid sorbent/acceptor phase; whereas, the diffusion of other components in the sample is hindered by the membrane [71]. This technique can relatively overcome the poor recognition ability of MIPs in aqueous media, which stems from adsorption of matrix impurities on the surface of MIPs, because direct contact of the sorbent and sample matrix is prevented [72]. With this view, Jayasinghe et al extracted aflatoxins in fish feed using ultrasound assisted MI-m-SPE followed by LC-MS/MS [73].…”
