“…Based on the concept of Green Chemistry, many scientists have paid more and more attention to room temperature ionic liquids (ILs), it also known as ionic liquids, which is literally a liquid organic salt composed purely of positive and negative ions [34] and it is a new type of green polar solvent in recent years. ILs can be used as solvents, porogenic agents, templates, functional monomer and so on.…”

Gastrodia elata is a famous traditional herb. It is a challenging task to efficiently separate the active ingredient Gastrodin (p-hydroxymethylbenzene-β-D-glucopyranoside) from gastrodia elata by simple procedure. According to the results of computer molecular simulation & UV-vis spectroscopy, water-soluble 1-vinyl-3-tetradecylimidazole bromide([C14VIM + ] [Br -]) was selected as the best ionic liquid functional monomer compared with methacrylic acid(MAA), acrylic acid(AA), 3-(2-carboxyethyl)-1-vinylimidazolium bromide ionic liquid (imidazole propionate, [COOHpvimBr]) and dehydroabietic acid [2-(acryloyloxy)ethyl] ester (DAAEE). The force between [C14VIM + ] [Br -] and GAS (with multiple hydroxyl groups) is stronger than other monomers with more polar groups. The molecular imprinted polymers (MIPs) and non-molecular imprinted polymers (NIPs) withhigh selectivity to gastrodin(GAS) were synthesized utilizing ([C14VIM + ] [Br -]) as a novel functional monomer. In addition, surface molecular imprinted polymers (SMIPs) and surface non-molecular imprinted polymers(SNIPs) supported on silica gel were also prepared. These polymers were characterized by infrared spectrum, scanning electron microscope, specific surface area tester and thermosgravimetric analyser(TGA). The adsorption performance of the MIPs and NIPs was investigated by adsorption kinetics experiment and static adsorption experiment. By Molecular Imprinting-SPE extraction(HPLC), the content of gastrodin in eluent (70% ethanol) was significantly increased compared with it in plant extract, which is better than that of SMIPs-SPE. The recoveries of the spiked samples for the GAS ranged from 97.75-103.43% with relative standard deviation values lower than 2.88%. The molecular imprinted polymer was a potential separation material for gastrodin.

“…The development of analytical methods promotes the examination of the efficacy, identity, and safety of chemicals or drugs. Numerous analytical methods, including high-performance liquid chromatography (HPLC), − spectrofluorometry, , ultraviolet–visible (UV–vis) spectrophotometry, − liquid chromatography-mass spectrometry (LC-MS/MS), , surface-enhanced Raman spectroscopy, and enzyme-linked immunosorbent assays (ELISAs), have been introduced for the determination of RhB in food samples. Today, several electrochemical methods − and nanotechnological applications − were used to detect the presence of RhB.…”

Rhodamine B, a synthetic dye, is used as a food additive to impart color to different foodstuffs to attract buyers. The aim of this study was to develop and validate an ultraviolet–visible spectrophotometric method for the identification and estimation of rhodamine B in rhodamine B-adulterated food articles. Upon reaction with HCl, rhodamine B produces a rose-pink color, exhibiting maximum absorption at 556 nm. The linearity, precision, and accuracy were analyzed statistically for validation. An aliquot of rhodamine B obeyed the Beer–Lambert law between 2 and 20 μg/mL and exhibited a linear regression curve with a correlation coefficient (R 2) of 0.9991. The limit of detection and limit of quantification were 1.15 and 3.5 μg/g, respectively. The detection was further confirmed by performing thin layer chromatography and 1H nuclear magnetic resonance of the sample with the pure rhodamine B. The proposed method for the determination and estimation of rhodamine B as a food coloring agent in this report is accurate and precise.

“…In conjunction with the properties of bCD, a number of methods have been developed that promote the incorporation of bCD with an IL, mainly because the presence of an IL has been proven to enable more chemical interactions between targeted analytes. [37][38][39][40][41][42] The term IL refers to a type of salt in the form of a liquid below 100 C or even at room or ambient temperature, of which the latter are also known as room-temperature ionic liquids (RTILs). 43 RTILs have begun to gain wide recognition as novel solvents within the eld of chemistry owing to the unique non-volatility, non-ammability, low viscosity, and electrochemical stability of ILs, which are benecial in various types of applications, especially in supramolecular materials.…”
