Simultaneous determination of multiple phytohormones in tomato by ionic liquid-functionalized carbon fibers-based solid-phase microextraction coupled with liquid chromatography-mass spectrometry

A rapid and sensitive ultra-performance liquid chromatography-tandem mass spectrometry method for determination of phytohormones in the medicinal plant saffron

“…38 As shown in Table 3, the ME of IAA and ABA was 80 ± 0.75% and 91 ± 2.60%, respectively, indicating that detection of targets was free from the ME. The proposed method was compared with analytical methods reported previously 39,40 with regard to sample amount, extraction solvent, elapsed time, linear range, recovery, and LOQ (Table 4). Low-toxicity and inexpensive extraction solvents were used to extract target analytes.…”

Recent advances in application and progress of advanced materials as adsorbents in sample preparation for plant growth regulators

“…The IL modified on the adsorbent could be conducive to improving the selectivity of the adsorbent to target analytes, because its hydrophobic-hydrophilic, polarity, and acid-base properties can be changed by selecting the cation and anion components. Jo et al synthesized ionic liquids containing different functional groups and modified the surface of carbon fibers with them to prepare five carbon fibers-IL (CFs-IL) with different functional groups [117]. The CFs-IL integrated properties of carbon fibers and IL, exhibit the high adsorption capacity and selectivity for PGRs.…”

Novel solid‐phase microextraction fiber coatings: A review

“…Five novel carbon fibers functionalized with various ILs possessing different anions and cation groups such as aliphatic and aromatic side chains (CFs-IL) for simultaneous determination of acidic, alkaline, and neutral phytohormones were synthesized through nucleophilic substitution reaction of haloalkane by Jon and co-workers [149]. Due to the hydrophobic, electrostatic, and π-π interactions and hydrogen bonding between analytes and ILs, CFs-IL-Methyl had the best adsorption effect for the simultaneous determination of multiple phytohormones in tomato sample under neutral conditions with a low LODs, good linearity range, and reliable accuracy and precision.…”
