Identification and analysis of active ingredients in traditional Chinese medicinal materials is essential for verifying herbal authenticity, potency, and safety. Our laboratory employs advanced chromatographic and spectroscopic techniques, including HPLC, UHPLC, GC-MS, and LC-MS/MS, to qualitatively and quantitatively characterize bioactive compounds in herbs, extracts, and finished formulations. These services support pharmacopoeia compliance, quality control, new product development, and regulatory submissions for manufacturers worldwide.
Technical Overview
Traditional Chinese medicinal materials contain complex mixtures of bioactive constituents, including alkaloids, flavonoids, glycosides, terpenoids, volatile oils, polysaccharides, anthraquinones, coumarins, and saponins. The identification and analysis of these active ingredients form the scientific foundation for evaluating herbal authenticity, quality grade, and therapeutic potency. Because the chemical composition of medicinal materials varies significantly with species, geographical origin, harvest season, processing method, and storage conditions, rigorous analytical testing is indispensable for modern herbal quality assurance.
Our identification and analysis platform integrates chromatographic separation with multiple detection technologies to achieve comprehensive characterization. Qualitative identification confirms the presence of characteristic marker compounds that verify botanical identity, while quantitative assays determine the exact concentration of index components against pharmacopoeial standards. Chromatographic fingerprint profiling further evaluates the overall chemical consistency between batches, which is particularly valuable for multi-herb formulations where single-marker analysis is insufficient. All testing is performed in accordance with the requirements of the Chinese Pharmacopoeia, United States Pharmacopoeia (USP), European Pharmacopoeia (Ph. Eur.), and applicable international guidelines.
Testing Samples
Raw Medicinal Herbs and Crude Drugs
Whole or cut crude botanical materials, including roots, rhizomes, stems, barks, leaves, flowers, fruits, seeds, and whole plants, as well as mineral and animal-derived medicinal substances. Testing verifies species authenticity and determines whether active ingredient levels meet pharmacopoeial limits prior to processing or distribution.
Processed Decoction Pieces
Herbal materials that have undergone traditional processing procedures such as stir-frying, honey-frying, steaming, wine-processing, or carbonizing. Analysis evaluates how processing modifies the chemical profile and confirms the transformation of key constituents, for example the conversion of raw glycosides during thermal treatment.
Herbal Extracts and Concentrates
Standardized extracts, fluid extracts, concentrate pastes, and powdered extracts produced by water extraction, ethanol extraction, or supercritical fluid extraction. Testing quantifies marker compound enrichment, calculates transfer ratios, and verifies extract standardization claims such as concentration percentages.
Finished Formulations and Patent Medicines
Granules, tablets, capsules, pills, oral liquids, tinctures, ointments, and other dosage forms containing single or multiple herbal ingredients. Analysis confirms batch-to-batch consistency, validates content claims on product labels, and supports release testing prior to market distribution.

Testing Methods
A multi-technology analytical strategy is applied according to the physicochemical properties of the target constituents and the requirements of the applicable monograph or study protocol.
- High-Performance Liquid Chromatography with UV or Diode Array Detection (HPLC-UV/DAD): the primary method for quantitative assay of non-volatile constituents such as flavonoids, glycosides, alkaloids, and phenolic acids, offering high precision and excellent reproducibility
- Ultra-High-Performance Liquid Chromatography (UHPLC): enhanced separation efficiency and shorter analysis time for complex multi-component quantification and fingerprint profiling
- Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS): high-sensitivity identification and quantification of trace constituents, structural confirmation of unknown compounds, and metabolite profiling
- Gas Chromatography and Gas Chromatography-Mass Spectrometry (GC/GC-MS): determination of volatile oils, essential oil composition, and residual solvents
- Thin-Layer Chromatography and High-Performance Thin-Layer Chromatography (TLC/HPTLC): rapid qualitative identification and identity confirmation as specified in pharmacopoeial monographs
- Fourier Transform Infrared Spectroscopy (FTIR): rapid screening and preliminary structural characterization of herbal powders and extracts
- Nuclear Magnetic Resonance Spectroscopy (NMR): structural elucidation and absolute quantification for research-grade applications
- DNA Barcoding and Molecular Identification: species-level authentication for closely related or morphologically similar herbal materials
All quantitative methods are validated or verified for specificity, linearity, accuracy, precision, range, and limit of quantification in accordance with ICH Q2(R1) analytical validation principles and pharmacopoeial method verification requirements.

FAQ
What standards are used for active ingredient analysis?
Testing is primarily performed according to the current edition of the Chinese Pharmacopoeia, with additional capability to apply USP, Ph. Eur., Japanese Pharmacopoeia, and in-house validated methods where specific monographs or customer requirements apply.
How much sample is required for testing?
Typical requirements range from 20 to 100 grams of solid material or 20 to 50 milliliters of liquid formulation, depending on the number of test items. Fingerprint and multi-component analyses may require additional quantities, and customers are advised to confirm specific requirements before submission.
What is the typical turnaround time?
Standard single-component quantification is generally completed within 5 to 7 working days. Fingerprint profiling, multi-component analysis, and structural identification projects may require 10 to 15 working days depending on method complexity and project scope.
Can unknown compounds be identified?
Yes. Unknown constituent identification is performed using LC-MS/MS and NMR combined with reference databases and literature comparison, delivering structural assignments with reported confidence levels.
Are certified reference materials used?
Quantification is performed using certified reference standards with documented purity and traceability wherever available. Where certified standards are not commercially accessible, qualified in-house standards are established and characterized according to recognized procedures.
