  • Toxic Alkaloids Analysis

    The Laboratory provides the analysis of toxic alkaloids in traditional medicines, including Aconite Alkaloids, Amygdalin, Aristolochic Acids, Artemisnin, Berberine, Bufotenine, Colchicine Alkaloids, Ephedra Alkaloids, Lobelia Alkaloids, Lovastatin, Methoxsalen, Solanaceous Alkaloids and Tetrahydropalmatine.
  • Aflatoxins Analysis

    The Laboratory provides the analysis of Aflatoxins B1, B2, G1 and G2 in traditional medicines.

Western Medicines

Western medicines are tested for compliance with Pharmacopoeia (BP, USP, EP, IP) or manufacturers' specifications. The Laboratory performs tests on products in various dosage forms, including injections, infusions, tablets, capsules, creams, eye/ear drops, sprays, ointments, lotions, tinctures, mixtures, emulsions, extracts and solutions.

The Laboratory conducts a large variety of tests, including identification, assay, dissolution, disintegration, related substances/chromatographic purity, water content, melting point, tablet hardness, loss on drying, loss on ignition, optical rotation, pH, refractive index, uniformity of dosage units, uniformity of weight, gravimetry and extractable volume.
