Extraction and Determination of Quercetin and Myricetin from Chamaecyparis obtusa by Ionic Liquids‐based Monolithic Cartridge

Abstract

A short ionic liquids (ILs)-based monolithic cartridge was prepared and used as the selective extraction sorbent. After the material was evaluated by field emission-scanning electron microscopy (FE-SEM), a new approach for the extraction and determination of quercetin and myricetin from Chamaecyparis obtusa (C. obtusa) by using ILs-based, monolithic cartridge system was developed. Chromatographic analysis was conducted on a C 18 column with UV detection at 372 nm, an eluting solution consisting of acetonitrile-water (25/75, V/V) as the mobile phase, and a flow rate of 0.7 mL•min -1 . A good linear relationship was demonstrated when the concentrations of quercetin and myricetin were in the range of 0.5-100.0 µg•mL -1 . The recoveries ranged from 101.6% to 104.6% and the interand intra-day relative standard deviations (RSD) were less than 5.0%. This method effectively removed the impurities and avoided tedious pretreatment. It provided a fast, economic and effective method for assaying trace drugs from natural plants.

Preparation and applications of hybrid organic–inorganic monoliths: A review

“…ILs are salts composed of cations and anions and are liquids at ambient temperatures []. In recent years, there has been increasing interest in ILs as novel solvents for synthesis, separation, electrochemistry, and process chemistry because of their unique properties that make them useful in a range of areas in modern chemistry []. Wang et al [] explored a room temperature, ILs‐mediated nonhydrolytic sol–gel protocol for fabrication of new molecularly imprinted HSMs.…”

Purification of Luteolin and Apigenin From Celery Leaves Using Hybrid Organic–inorganic Monolithic Cartridge

“…[12,13] On the other hand, the methods for purifying the target compounds from the solvent extract require improvement. Solid-phase extraction (SPE) is the most widely used target-substrate pretreatment of complicated matrices, [14,15] with ongoing research focused on finding suitable SPE materials for specific applications.…”

A Sensitive and Low-cost Analytical Method for the Electrochemical Determination of Quercetin, Based on 1-Ethylpyridinium Bromide/Carbon Paste Composite Electrode

“…About the quantification of QCT, some recent and relevant reports include the exploitation of a graphite oxide and ionic liquid modified electrode (Jiuji et al, 2013), or the use of Ag nanoparticles/1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide based β-cyclodextrin/epichlorhydrin composite electrode (Franzoi et al, 2010). On the other hand, the exploitation of ionic liquids (ILs) for the extraction of phenolic compounds from herbal products (Liu et al, 2014) and medicinal plants (Xu et al, 2012;Bogel-Lukasik et al, 2010a;Zhu et al, 2011) has been demonstrated during the past few years. In fact, ILs can create various types of interactions with substrates and organic compounds, hydrogen bonds, van der Waals, dipole-dipole, dispersive and electrostatic forces being the most common of these interactions (Bogel-Lukasik et al, 2010a;Bogel-Lukasik et al, 2010b;Bogel-Lukasik et al, 2010c;Domanska & Bogel-Lukasik, 2005).…”
