Molecularly imprinted polymers prepared by Pickering emulsion method with lignin as stable particle were used as dispersants in matrix solid-phase dispersion, followed by ultra high performance liquid chromatography with tandem mass spectrometry to research the degradation behavior of matrine in soil. The molecularly imprinted polymers have regular morphology and uniform particles. Moreover, the adsorption experiments and the conditions of matrix solid-phase dispersion were discussed. With the optimal conditions of matrix solid-phase dispersion, the recoveries of matrine were 95.4-98.2%, relative standard deviations were 0.6-5.1%, and the detection limit was 5 ng/g. Moreover, the degradation behavior of matrine in soil was researched, it indicated the half-life of matrine was 2.7-3.2 days, and it was an environmentally friendly botanical pesticide. The method was successfully applied to separate and analyze matrine in soil samples can decrease analysis time, save organic solvents, and improve the selectivity.

“…There have been a few reports on the separation of these three compounds mainly from the root of Sophora flavescens Ait. [8], Sophora alopecuroides L. [9], and radix Sophorae tonkinesis [10,11]. Extractions of these components have been performed using SPE, CE, and pH-zone-refining CCC [12,13].…”

Double-templated molecularly imprinted polymers with specific recognition of three matrine-type alkaloids were prepared using matrine and oxymatrine as the template molecules. An approach based on double-templated molecularly imprinted solid-phase extraction coupled with high-performance liquid chromatography and tandem mass spectrometry was then developed to extract and purify matrine, oxymatrine, and sophocarpine from Sophora moorcroftiana in the Tibetan plateau herbs. The polymers were characterized by Fourier-transform infrared spectroscopy and scanning electron microscopy. Their adsorption characteristics were evaluated using adsorption kinetics, isotherms, selectivity, and recycling experiments. This polymer exhibited excellent molecular recognition ability and good selectivity. The obtained polymers as adsorbent was further used for the determination of three matrine-type alkaloids coupled to high-performance liquid chromatography with tandem mass spectrometry, the recoveries of three matrines spiked at three concentration levels in samples were 73.25-98.42% (n = 5) with a relative standard deviation less than 6.82%. The limits of detection for the method were 9.23-15.42 μg/kg (S/N = 3). This proposed method was assessed to be an effective method for simultaneous extraction, isolation, and identification of matrine, oxymatrine, and sophocarpine from Sophora moorcroftiana.

“…Compared to the use of solid phase extraction (SPE) [ 9 ], microwave-assisted extraction (MAE) [ 59 ], supercritical fluid extraction (SFE) [ 60 ] and molecular Imprinting Technique (MIT) [ 61 ], the QuEChERS method is fast, efficient, time-saving and simple to use, eliminating the need for complex clean-up processes as well as reducing pretreatment time and the use of organic solvents. Compared to the application of thin layer scanning [ 26 , 62 ], high-performance liquid chromatography [ 63 , 64 ] and capillary electrophoresis [ 65 ] methods for the determination of matrine bases, the LC-MS/MS method has high detection sensitivity and accuracy and low detection limits, thus, ensuring rapid and accurate analysis results of the samples.…”

A method was developed for the determination of matrine residues in quinoa (Chenopodium quinoa Willd.) plants and soil by liquid chromatography triple quadrupole tandem mass spectrometry (LC-MS/MS) with QuEChERS clean-up. Matrine from soil, quinoa roots, stems, leaves and seeds was extracted with 25% ammonia, 20 mL acetonitrile/methanol, salted with sodium chloride (NaCl) and purified with anhydrous magnesium sulfate (MgSO4), N-propyl ethylenediamine (PSA) and graphitized carbon black (GCB). Then a chromatographic separation was performed on a Shim-pack XR-ODS II (75 mm × 2.0 mm, i. d., 2.2 µm) column with a gradient elution of 5 mmol/L ammonium formate-methanol as the mobile phase and monitored in multiple reaction monitoring modes (MRM) in electrospray positive ionization mode. The results showed that in the range of 0.005~1 mg/L, the linear correlation coefficients of matrine in the five matrices were all above 0.999. The LOQs for soil, quinoa roots, stems, leaves and seeds were 0.005, 0.005, 0.01, 0.01 and 0.005 mg/kg, respectively. The mean recoveries ranged from 74.42% to 98.37%, with RSDs of 1.25–6.84% at the three concentration addition levels. The average intra-day and inter-day recoveries were 73.92–92.36% and 78.56–90.18%, respectively, with RSDs below 8.72% and 9.43%. The recoveries and reproducibility of the method were superior. The method was used to determine the actual samples, which indicated that the half-lives of matrine in quinoa seeds, leaves, stems and soil were 1.28–1.32, 1.03–1.21, 0.81–0.92 and 0.93–0.97 d. It has a half-life below 30 d, which is an easily dissipated pesticide. The method is simple, sensitive, accurate, reliable and applicable to a wide range of applications, and it can achieve the rapid multi-residue determination of matrine to a certain extent. Next Generation Sequencing was used to explore the effects of exposure to high and low doses of matrine on soil bacterial communities and the composition of the three soils in the Qinghai Province (Haixi, Haidong and Haibei). The results showed that the number of ASVs increased significantly after treatment with matrine at an effective dose of 0.1 mg/kg than after treatment with matrine at an effective dose of 5.0 mg/kg. Similarly, bacterial abundance was higher after 0.1 mg/kg of matrine treatment than after 5.0 mg/kg of matrine treatment. The inhibitory effect on some bacterial flora was enhanced with an increase in matrine application, while the inhibitory effect on bacterial flora was weakened with time. Applying a certain dose of matrine e changed the relative abundance of the dominant bacterial genera of the soil bacteria.
