Backed by advanced instrumentation and experienced analysts, we deliver reliable data that accelerate the modernization and internationalization of traditional Chinese medicine research.
Technical Overview
Indicator analysis for TCM key special projects refers to the systematic analytical evaluation of quality, safety, and efficacy-related parameters required by national key research and development programs focused on traditional Chinese medicine modernization. These projects, which cover areas such as classic formula development, herbal resource utilization, innovative drug discovery, and international standardization, demand rigorous and reproducible analytical data at every research stage.
A typical indicator analysis framework addresses three complementary dimensions: quality indicators that characterize the chemical composition of herbal materials and products, safety indicators that screen for contaminants and toxic constituents, and efficacy-related indicators that link measurable components to pharmacological activity. Testing is performed in accordance with the Chinese Pharmacopoeia (current edition), national standards (GB series), and project-specific protocols established by program authorities.
Because TCM materials are chemically complex and biologically variable, indicator analysis must combine multiple orthogonal techniques, robust sample preparation, and method validation to ensure that reported results are accurate, traceable, and defensible in both regulatory and academic contexts.
Testing Samples
Raw Herbal Materials and Decoction Pieces
Whole herbs, sliced decoction pieces, and processed materials from all major categories, including root and rhizome drugs, floral materials, fruits and seeds, barks, and animal- or mineral-derived substances. Sample intake protocols follow pharmacopoeial sampling rules to guarantee representativeness across batches.
Extracts and Intermediate Products
Standardized extracts, fractionation products, granulation intermediates, concentrated pastes, and purification fractions generated during process research. These samples are analyzed to monitor marker transfer rates, monitor batch consistency, and support process optimization studies.
Finished Formulations
Tablets, capsules, granules, oral liquids, pills, injections, and topical preparations. Formulation testing integrates release or dissolution behavior, content uniformity, and stability-indicating assays alongside conventional quality indicators.
Biological and Pharmacological Study Samples
Plasma, serum, tissue homogenates, urine, and organ samples collected from pharmacokinetic and pharmacodynamic studies, analyzed to determine compound exposure, metabolite profiles, and effective constituent identification.
Reference and Comparison Samples
Authenticated reference crude drugs, chemically defined reference substances, and commercially sourced comparison samples used to establish baselines, verify methods, and support equivalence or superiority assessments.
Testing Items
Indicator packages are configured according to project objectives, and typically include the following categories:
- Quantitative determination of active and marker constituents, including alkaloids, flavonoids, glycosides, terpenoids, phenolic acids, saponins, anthraquinones, and volatile oils.
- Chromatographic fingerprint profiling and multi-component characterization for batch consistency and authenticity evaluation.
- Heavy metal and harmful element limits, including lead, cadmium, arsenic, mercury, and copper.
- Pesticide residue screening covering organochlorine, organophosphorus, pyrethroid, and carbamate compounds.
- Mycotoxin determination, with emphasis on aflatoxins B1, B2, G1, and G2.
- Sulfur dioxide residue testing for sulfur-fumigated materials.
- Microbiological limits, including total aerobic microbial count, combined yeast and mold count, bile-tolerant gram-negative bacteria, and specified organisms such as Escherichia coli and Salmonella.
- Ash values, extractable matter, water content, and disintegration or dissolution performance.
- Endotoxin and sterility testing for injectable preparations.
- Species authentication and adulteration screening using DNA barcoding and microscopic identification.
- Pharmacokinetic parameters such as Cmax, Tmax, AUC, half-life, and bioavailability in study matrices.
- Stability studies covering influential factor testing, accelerated conditions, and long-term storage.
Testing Methods
Method selection is driven by matrix complexity, target sensitivity, and applicable regulatory requirements. Core techniques include:
- High-performance liquid chromatography (HPLC) with diode-array detection for routine quantification of non-volatile markers.
- Ultra-performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) for multi-residue trace analysis and metabolite identification.
- Gas chromatography with flame ionization, electron capture, or mass spectrometric detection (GC-FID, GC-ECD, GC-MS) for volatile constituents and pesticide residues.
- Inductively coupled plasma mass spectrometry (ICP-MS) and atomic absorption spectroscopy for elemental impurity determination.
- Thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) for qualitative identification and rapid screening.
- Ultraviolet-visible spectrophotometry for total content assays of compound classes such as total flavonoids and total polysaccharides.
- Enzyme-linked immunosorbent assay (ELISA) and lateral-flow screening for rapid mycotoxin detection.
- DNA barcoding based on ITS2, psbA-trnH, and matK regions for molecular authentication.
- Conventionally cultured and rapid microbiological methods for microbial limit testing.
- Kjeldahl nitrogen determination and loss-on-drying analysis for classical general chemistry indicators.
All quantitative methods are validated for specificity, linearity, range, accuracy, precision, detection limit, quantitation limit, robustness, and solution stability before sample analysis. Where pharmacopoeial monographs exist, verified official methods are applied; otherwise, in-house methods are developed, validated, and documented under controlled quality system procedures.

FAQ
What is the typical turnaround time for indicator analysis?
Routine single-indicator tests are generally completed within five to ten working days after sample acceptance. Multi-component profiling, full safety panels, and method development projects require individualized schedules agreed upon during technical consultation, typically ranging from two to six weeks.
How should samples be prepared and submitted?
Samples should be sealed, labeled, and accompanied by a submission form describing the material name, batch number, matrix type, storage conditions, and the indicators requested. Herbal materials are usually submitted in quantities of 100 grams or more per batch, while finished products should include complete primary packaging when stability or release testing is required.
Which standards govern the acceptance criteria?
Acceptance criteria are drawn from the current Chinese Pharmacopoeia, applicable national and industry standards, project task documentation, and product-specific registration specifications. Where multiple standards exist, the strictest applicable limit is generally adopted unless otherwise agreed.
Can custom indicator panels be developed for novel materials?
Yes. For materials without established monographs, the laboratory develops and validates indicator systems based on chemical characterization, literature review, and component transfer studies, delivering a defensible analytical basis for subsequent standard setting.
What deliverables are provided upon completion?
Clients receive a formal test report containing sample information, applied methods, validated parameters, quantitative results, comparison against limits, chromatograms or spectra where applicable, and clear conclusions.
