Six different processing techniques for Poria cocos (Schw.) Wolf UPLC-ESI-MS/MS Data (negative)

ABSTRACT: We designed a detailed system based on the characteristics of different processing methods to classify Poria cocos into six distinct groups: Sun-dried (SG), Fresh-cut (XQ), Sweat-treated (FH), Steam-treated (ZH), Sweat and steam-treated (FHZH), and Shade-dried (YG). It also contains the negative ion mode mass spectrometry data of quality control samples (QC) and mycelium (FLS) from Shade-dried (YG) group. UPLC-MS/MS analysis was performed on a UPLC system (Acquity I-Class, Waters Corporation, Milford, MA, USA) coupled to a Xevo G2-XS QToF mass spectrometer (Waters Corporation, Manchester, UK), utilizing a Waters HSS T3 column (1.8 micron, 100 mm x 2.1 mm). Solvent A (formic acid/water (0.1:99, v/v)) and solvent B (formic acid/acetonitrile (0.1:99, v/v)) were employed as the mobile phase. The elution gradient used for separation was as follows: 50% solvent B at 0 minutes; 55% solvent B at 4 minutes; 58% solvent B at 9 minutes; 68% solvent B at 10 minutes; 80% solvent B at 15 minutes; 85% solvent B at 17 minutes; returning to 50% solvent B at 18 minutes, which was maintained until 19 minutes. The flow rate was set at 0.3 mL/min, and the column temperature was controlled at 35 degrees Celsius. Mass spectrometric analysis was conducted using a QTOF instrument equipped with a Zspray ESI source (Waters Corporation, Manchester, UK) operating in negative ionization modes. The ESI source operated at 120 degrees Celsius, with a desolvation temperature of 360 degrees Celsius, a spray voltage of 3.5 kV, a cone gas flow of 50 L/h, and a desolvation gas flow of 800 L/h. For the fast data-dependent acquisition (DDA) setting, survey scans were collected over a mass range of 50-800 Da with a scan time of 0.1 seconds. Data were acquired in centroid format, and the maximum allowable mass error was set at ±10 ppm. A dual dynamic collision energy function (6-15 eV for low m/z 50 and 60-90 eV for high m/z 800) was applied for the measurement scans. Leucine-enkephalin solution (10 ng/L) was infused at a constant flow rate of 10 microliter/min for LockSpray calibration. The method was configured to analyze the top five most intense ions from the survey scans, with dynamic exclusion enabled for 15 seconds. This study's doi:10.1016/j.fochx.2026.103609.

Project description:This study measured the differential expression of genes from a single clonal Daphnia pulex isolate obtained from an eutrophic flooded opencast mine near Gräfenhain (Saxony, Germany) and has been kept in the laboratory since 2002. The daphniids (50 adult animals per batch) were raised in 3-L glass beakers under a 16 h:8 h L:D photoperiod. Three-quarter of the culture medium (M4) was renewed once a week, and the animals were equally fed ad libitum with algae (Desmodesmus subspicatus; SAG 53.80, Göttingen, Germany). Long-term-acclimated animals were kept at three different temperatures (i.e., 10 ± 0.5°C, 20 ± 0.3°C, and 24 ± 0.3°C) under normoxia (Po2 ≥ 20 kPa) for at least twelve weeks. Time-resolved experiments (acute heat stress) were carried out with long-term 20°C acclimated animals, which were exposed for three different time intervals (2, 4, and 8 h) to either 30 ± 0.2°C (test conditions) or 20 ± 0.3°C (control conditions). For this, 50 animals each were rapidly transferred with a sieve (mesh size: 1.2 mm) from 20°C-medium to a set of beakers containing 30°C-medium. As control, 50 animals each were transferred from 20°C-medium to another set of beakers with 20°C-medium. Only adult female animals with a body length of 2−2.5 mm (between the base of the apical spine and the anterior part of the head) and carrying parthenogenetic eggs and embryos were used for experiments. Animals were not fed during short-term exposures. During experiments, all animals were in good physical condition. After thermal acclimation or heat exposure, animals were transferred into 1.5-ml microcentrifuge tubes and shock-frozen in liquid nitrogen after removing adhering water with a tissue paper. Samples were short-term stored at -80°C. For all experimental conditions, four independent replicates (50 animals each) were analyzed. This GEO record is for the contrasts between animals conditioned to 10 degrees Celsius (condition 1) versus 20 degrees Celsius (condition 2), 10 degrees Celsius (condition 1) versus 24 degrees Celsius (condition 3), and 20 degrees Celsius (condition 2) versus 24 degrees Celsius (condition 3)

Project description:<p>The sample to be tested was fully ground into powder in the grinder, 50 mg of the sample was freeze-dried, 1000 μL of the extraction solution containing the inner target was added (methanol:acetonitrile:water, 2:2:1, v/v/v, internal standard concentration 20 mg/L) and vortex mixed for 30 s; then add the steel ball to the 45 Hz grinder for 10 min, ultrasonic 10 min; the sample to be tested is obtained after filtration. When detecting metabolites, metabolite determination was performed based on the LC-MS system, which mainly consists of Waters Acquity I-Class PLUS ultra-high performance liquid tandem and Waters Xevo G2-XS QTof high-resolution mass spectrometer. Meanwhile, the Waters Acquity UPLC HSS T3 column (1.8 um 2.1 x 100 mm) was used as the chromatographic column. Positive and negative ion modes were used to determine the metabolites. Mobile phase A: 0.1% formic acid aqueous solution; Mobile phase B: 0.1% acetonitrile formate. The mobile phase conditions of liquid chromatography were as follows: the flow rate was 400 μL/min, 0.0 min: 98% flow A, 2% flow B; 0.25 min: 98% flow A, 2% flow B, 10.0 min: 2% flow A, 98% flow B; 13.0 min: 2% flow A, 98% flow B; 13.1 min: 98% flow A, 2% flow B; 15.0 min: 98% flow A, 2% flow B. MSe mode controlled by acquisition software (MassLynx v4.2, Waters) was used for primary and secondary mass spectrum data acquisition. ESI ion source parameters are as follows: Capillary voltage, 2500 V (positive ion mode) or -2000 V (negative ion mode); Cone hole voltage, 30 V; Ion source temperature, 100 °C; Desolvent temperature, 500 °C; Air flow rate, 50 L/h; Desolvent gas flow rate, 800 L/h; Plastic-nucleus ratio (m/z) collection range 50-1200 m/z. In the qualitative and quantitative analysis of metabolites, the original data collected by MassLynx v4.2 were processed by the Progenesis QI software for peak extraction, peak alignment, and other data, and the metabolites were identified based on the Progenesis QI software online METLIN database. Then, based on the results of the total score, MS2 score, and mass error (ppm), the metabolites were qualitatively determined.</p>
