“…Ease of synthesis, physical robustness, and resistance to acid and base [1,3,4] are additional attractive features of MIPs. Consequently, MIPs have been widely used in many fields, including sensors [5,6], catalysts [7,8], artificial enzyme [9,10], and solid-phase-extraction materials [2,[11][12][13]. However, these synthetic materials often suffer from the disadvantage that a substantial initial amount of the template is needed in the preparation of MIP [14], which hampers the potential applicability of MIPs for expensive or poorly soluble templates.…”

One of the main challenges in the preparation of molecularly imprinted polymers (MIPs) is the substantial initial amount of template needed because of the requirement of high load capacities for most applications. A new strategy of macromolecular crowding was suggested to solve this problem by reducing the amount of template in the polymerization recipe. In a ternary porogenic system of polystyrene (PS) (crowding agent), tetrahydrofuran, and toluene, an imprinted monolithic column with high porosity and good permeability was synthesized using a mixture of ellagic acid (template), acrylamide, and ethylene glycol dimethacrylate. The effect of polymerization factors, including monomer-template molar ratio and the molecular weight and concentration of PS, on the imprinting effect of the resulting MIP monoliths was systematically investigated. At a high ratio of monomer-template (120:1), the greatest imprinting factor of 32.4 was obtained on the MIP monolith with the aid of macromolecular crowding agent. The PS-based imprinted monolith had imprinting even at the extremely high ratio of functional monomer to template of 1510:1. Furthermore, an off-line solid-phase extraction based on the ground MIP was conducted, and the purification recovery of ellagic acid from pomegranate-rind extract was up to 80 %. In conclusion, this approach based on macromolecular crowding is simple, and is especially valuable for those applications of MIP preparation for which a rare template is used.

“…To optimize the chromatographic conditions, a 3 3 Box-Behnken factorial design triplicated at the central point (15 runs) was performed for the screening of significant conditions that affected the separation of taxifolin. 21 The factors chosen for evaluation and their respective levels in the experimental design are summarized in Table 2.…”

“…1 Due to the health significance of these compounds, some analytical methods have been developed for their separation, identification and quantification in natural products. [2][3][4] Polyphenols have a wide variability of chemical structures, which differ in polarity and size, from simple phenolic compounds to oligomers. Additionally, they are found at low concentration levels in natural products.…”

The aqueous extract of the bark of Pinus pinaster has a high concentration of polyphenols represented by a mixture of procyanidins, besides taxifolin, phenolic acids, cinnamic acids and their glycosides. Its quality control is specified in the United States Pharmacopeia, and the assay test is performed by determination of the total procyanidins content. However, determining the individual polyphenol content may represent an additional quality parameter for this extract. In this sense, the present study aimed to develop and optimize a method of high performance liquid chromatography with photodiode array detection (HPLC-PDA) for quantification of taxifolin in the bark extract of P. pinaster, using a 3 3 Box-Behnken factorial design. The proposed method was validated for specificity, linearity, limits of detection and quantification, precision, accuracy and robustness and it has shown that taxifolin may be used as a chemical marker for quality control of the bark extract of P. pinaster.
