Firstly, the immunomodulatory effects of TH on mice were analyzed and confirmed by monitoring body weight changes, organ indices, serum results, and TCR sequencing. Secondly, the prototype components absorbed into blood in plasma after administration of TH ethanol extract (THE) were analyzed and identified by UPLC-Q-Exactive Orbitrap MS, and ten prototype components were characterized, mainly phenolic acids and flavonoids. Finally, the obtained plasma components were input into the SwissTarget Prediction tool for drug target prediction, and disease targets were obtained from the Genecard and DrugBank databases. Subsequently, a protein-protein interaction (PPI) network was constructed to screen and determine core targets such as AKT1, STAT3, HIF1A. By identifying the plasma components of THE and their predicted core targets, this study provides a pharmacological basis for further investigation into the immunomodulatory mechanisms of TH.</div></div>","PeriodicalId":277,"journal":{"name":"Chinese Journal of Analytical Chemistry","volume":"54 9","pages":"Article 100761"},"PeriodicalIF":1.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148996518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We compared the herb pair &lt;em&gt;Magnolia officinalis&lt;/em&gt;–&lt;em&gt;Glycyrrhiza uralensis&lt;/em&gt; prepared as a traditional co-decoction (MG) and as reconstituted formula granules (MGFG). SMAs were enriched by centrifugation followed by dialysis to yield MG-SMAs and MGFG-SMAs (0, 30, and 60 min re-decoction). An excipient-containing model was generated by adding dextrin, and the corresponding assembly-enriched colloidal fraction was operationally designated MGE-SMAs. We systematically compared assembly morphology and solution-phase colloidal properties using scanning electron microscopy (SEM) and dynamic light scattering (DLS) and probed the assembly microenvironment using Fourier-transform infrared spectroscopy (FT-IR) and ultraviolet–visible spectroscopy (UV–vis). Chemical profiling was performed by Ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry/mass spectrometry (UPLC-Q-TOF-MS/MS) combined with multivariate analyses, and representative constituents were quantified by High-performance liquid chromatography (HPLC). Anti-Staphylococcus aureus activity was evaluated by growth-inhibition curves (OD&lt;sub&gt;600&lt;/sub&gt;), MIC/MBC assays, and Live/Dead staining. The MG decoction presented a highly heterogeneous dispersion (1040.97 ± 91.00 nm; PDI 0.98 ± 0.02), whereas its centrifugation- and dialysis-derived colloidal fraction, MG-SMAs, exhibited a narrower nanoscale particle-size distribution (229.43 ± 3.27 nm; PDI 0.15 ± 0.07) with a similarly weakly negative ζ-potential and reduced conductivity, consistent with enrichment of a defined colloidal fraction. Addition of dextrin and reconstitution from granules increased dispersity (PDI 0.56–0.71) and reduced |ζ| (≈ −7 mV), indicating excipient- and processing-induced heterogeneity. Re-decoction was associated with time-dependent changes in the colloidal properties of MGFG-derived fractions.

UPLC-Q-TOF-MS/MS revealed broadly overlapping component coverage but a preparation-dependent redistribution of metabolites, and HPLC confirmed selective enrichment and depletion trends among marker compounds.
