Why Natural Product Metabolomics?
Natural product matrices are dominated by secondary metabolites and are highly sensitive to variables such as origin, harvest season, processing, and extraction. LC–MS/MS metabolomics provides an efficient way to compare profiles, prioritize key compounds, and link chemical changes to biological outcomes.
Questions this analysis can help answer
- What are the key secondary metabolites in my medicinal plant, extract, or formula?
- How do batches differ across origin, cultivation conditions, processing, or storage?
- Which compounds are absorbed into serum or distributed into target tissues after dosing?
- Which endogenous pathways shift after treatment (e.g., lipids, amino acids, bile acids) and what does that suggest mechanistically?
- Which differential metabolites and pathways can support publishable conclusions and follow-up validation?

Detectable Metabolite Coverage: Natural Product LC–MS/MS
This service profiles plant secondary metabolites in natural products and herbal materials, with optional endogenous metabolomics for in vivo studies. Detection is influenced by matrix, extraction, and ionization response.
Typical detection: ~600–1000+ plant secondary metabolites per run (matrix-dependent).

Advantages of Our Natural Product Metabolomics Service
- Deep reference libraries for confident annotation
TCM-focused library capacity: 39,000+ total entries, including 5,000+ TCM standards, 14,000+ manually curated active constituents, and 20,000+ metabolite spectra generated from in vitro incubation models (for metabolite interpretation).
- Endogenous/metazoan metabolite library
10,000+ metabolites with 2,500+ standard-supported entries providing RT + MS1 + MS2 evidence (when applicable to the module).
- Standard-supported, multi-dimensional identification options
Highest-confidence reporting can include RT + accurate mass (MS1) + MS/MS (LC–MS/MS) evidence, with match scoring and spectra visualization for key findings.
- Quality control built into routine production
Multi-layer QC strategy (e.g., pooled QC injections, blanks, internal standards, signal stability monitoring, RT drift checks, mass accuracy checks) to improve reproducibility and interpretability.
- Scalable production experience
High annual sample throughput supports consistent execution for both pilot studies and larger experimental designs (capacity planning available on request).
Study Design Support: Recommended Comparisons and Experimental Strategies
We provide practical study design guidance to help you obtain interpretable, publication-ready metabolomics results.
- Group comparison: Control vs treatment, batch/origin, processing (Paozhi), or extraction method.
- Dose–response / time-course: Best for absorbed constituents and mechanism-focused pathway changes.
- Multi-factor design: Separate effects such as origin × processing or cultivar × environment with balanced sampling.
- QC & replicates: Pooled QC, blanks, internal standards, and randomized run order to control drift and batch effects.
Replicate tip: For discovery studies, prioritize biological replicates (a common starting point is ≥6 per group when feasible).
Analytical Platform: UPLC–Orbitrap LC–MS/MS and Key Parameters
We use an industry-standard UPLC–high-resolution Orbitrap LC–MS/MS workflow optimized for natural product complexity.
UPLC System
- Waters ACQUITY UPLC I-Class (or equivalent UPLC platform)
- Why it matters: high-pressure UPLC improves separation of isomers and co-eluting phytochemicals and supports stable retention times.
High-Resolution Mass Spectrometer (HRMS)
- Thermo Scientific Q Exactive series Orbitrap (configuration dependent)
Common acquisition characteristics (method-optimized per project):
- Ionization: ESI/HESI in positive and negative modes
- Mass accuracy: typically ≤5 ppm after calibration (project-run dependent)
- MS1 resolution: commonly 70,000–120,000 at m/z 200
- MS/MS resolution: commonly 17,500–30,000 at m/z 200
- Scan range: commonly m/z 70–1,050 (method dependent)
- Acquisition modes: DDA and/or DIA (selected based on coverage vs. annotation goals)
Final acquisition settings are optimized based on matrix complexity (plant tissue vs. extract vs. serum/tissue), expected compound classes, and study objectives.
