Astragalus Extract
Astragalus Root Extract is a specification-defined botanical ingredient for Australian pharmaceutical and formulation-development projects. Commercial material may be identified as Astragalus mongholicus or by the widely used trade and pharmacopoeial name Astragalus membranaceus, depending on the source standard and supplier documentation.
The former page incorrectly identified this material as Scutellaria baicalensis, which is a different botanical and must not be used as an Astragalus identity. Request the current specification, identity method, batch COA and sample before approving a grade.
Material Identity & Specification
Botanical identity: Confirm the exact accepted name, declared synonym, author citation and reference standard on the specification and COA.
Plant part: Root. Other plant parts should not be accepted without a separate technical and regulatory assessment.
Form: Dry root extract powder; colour and flow depend on extract concentration, carrier and processing.
Common specification approaches: Astragaloside IV, total saponins, polysaccharides or an extract ratio may be used to describe different grades. These measures are not interchangeable. Compare the marker definition, analytical method, calculation basis, reference standard, extraction solvent, native extract ratio and carrier.
Identity control: Review a suitable botanical or chromatographic identity test. A marker assay alone does not prove species identity.
Applications & Formulation
Potential formats include tablets, capsules and dry botanical blends, plus other specification-led projects after the intended product category and regulatory pathway are confirmed.
Solubility and dispersibility: Do not assume that an extract powder is freely water soluble. Test dispersibility, sedimentation, colour, flavour, pH behaviour and physical stability in the finished matrix.
Processing checks: Assess carrier contribution, moisture, hygroscopicity, particle size, powder flow, blend uniformity, heat exposure and storage stability during development.
Documents & Enquiries
Before purchase, request the current specification and batch COA together with available TDS, SDS, botanical identity evidence, analytical method or chromatogram, extraction-solvent and carrier declarations, microbiological limits, heavy metals, pesticide residues and residual solvents.
For a useful enquiry, include the required species naming standard, plant part, marker or extract-ratio target, analytical method, dosage format, destination market, trial quantity, estimated annual volume and document list.

FAQ
Is Scutellaria baicalensis an Astragalus species?
No. It is a different botanical. Astragalus material must be supported by species-specific identity documentation.Are astragaloside IV and Astragalus polysaccharide specifications directly comparable?
No. They measure different constituent groups and may use different methods and calculation bases. Compare complete specifications rather than percentage alone.Does a high astragaloside IV percentage prove botanical identity?
No. Marker content and botanical identity are separate quality questions. Review both the assay and a suitable identity test.What should be included with a sample request?
Provide the intended product format, species and plant-part requirement, target marker or ratio, analytical method, required documents, trial quantity and expected annual volume.
