“…In recent years, several studies on the occurrence and separation of TSPEO homologs have been published. ,,− Many kiwifruit, peach, and cherry samples have been analyzed, which demonstrated that TSPEOs are ubiquitous in fruits in China, with TSP16EO as the dominant oligomer, similar to the average polymerization degree of commercial TSPEO mixture . TSPEO residues have also been suggested to be associated with pesticide use during fruit growth .…”

Tristyrylphenol ethoxylates (TSPEOs) have been increasingly used in pesticide formulations as inert ingredients in China, but little information exists on the dissipation behavior of TSPEOs in foodstuffs. In this work, a rapid method for measuring TSPEO homologs in lettuce using QuEChERS and HPLC-MS/MS was established. This method was used to study the dissipation and distribution profiles of TSPEOs in lettuce. TSPEO homologs degraded rapidly under greenhouse and field conditions, with half-lives of 2.18–5.39 and 1.82–5.52 days, respectively. TSPEOn (n = 6–9) were relatively persistent in the field. The distribution profiles showed an obvious difference between the two conditions. TSPEOn (n = 14–18) degraded to shorter-chain TSPEOs with time, and a two-peak (TSP16EO and TSP10EO) homolog distribution profile occurred between 7 and 14 days of treatment under greenhouse conditions. This work improves the understanding of the dissipation behavior of TSPEO homologs in lettuce.

“…150 Jiang et al reported a modified QuEChERS method for fast and simultaneous determination of alkylphenol ethoxylates in leafy vegetable samples while coupled with ultrahigh-performance supercritical fluid chromatography−tandem mass spectrometry. 151 This method Reduction/integration of steps strategies combine several preparation procedures simultaneously to cut down the time consumption. By coupling with the appropriate detection system, better analytical performance can be obtained compared to the individual methods.…”

“…Seiwert et al combined the ACQUITY UPC 2 system with SYNAPT GS2 Q-TOF for the determination of trace organic chemicals and ozonation products of metformin in municipal wastewater [ 17 ]. Jiang et al used the Nexera UC SFC system in tandem with the LC/MS triple quadrupole mass spectrometer for rapid determination of alkyl phenols and ethoxy compounds in leaf vegetables [ 18 ]. However, there are few studies on supercritical fluid chromatography coupled with ion mobility quadrupole time-of-flight mass spectrometry (SFC/IM-QTOF-MS).…”

In this study, matrix solid phase dispersion (MSPD) microextraction combined with supercritical fluid chromatography-ion mobility quadrupole time-of-flight mass spectrometry (SFC/IM-QTOF-MS) was used to analyze the multipolar compounds in plant tea. The parameters of stationary phase, mobile phase, make-up solution, temperature, and back pressure were optimized. The target analytes were gradient eluted in 8 min by supercritical CO2 on a Zorbax RX-SIL column. Collisional Cross Section (CCS) values for single and multiple fields were measured. A series of validation studies were carried out under the optimal conditions, and the linear relationship and reproducibility were good. The limits of detection were 1.4 (Scoparone (1))~70 (Naringenin (4)) ng/mL, and the limits of quantification were 4.7 (Scoparone (1))~241 (Naringenin (4)) ng/mL. The recoveries of most compounds ranged from 60.7% to 127%. As a consequence, the proposed method was used for the separation and quantitative analysis of active ingredients in caulis dendrobii.
