Arjuna
Arjuna suppliers and sourcing guide
Arjuna is Terminalia arjuna, a large tree in the Combretaceae family that grows along rivers in India, and the trade uses its thick, pale bark. Bark is stripped, dried and milled to a powder, or extracted with water or water-ethanol and dried. Extracts are usually standardized to tannins or total polyphenols, and some to arjunolic acid or arjunic acid by HPLC.

Forms and grades of arjuna
Suppliers sell different products under the same name. Specify the one you need.
Bark powder
Dried, milled bark sold by mesh size without standardization.
Tannin-standardized extract
Water or hydroalcoholic bark extract sold with a declared tannin or polyphenol content, often 20% to 40%.
Triterpene-standardized extract
Extract with a declared arjunolic or arjunic acid content by HPLC.
Organic
Bark powder or extract from certified organic or wild-collected sources, with the certificate tied to the lot.
What to check on the COA
Compare each result with your own specification when the lot arrives.
- Identity (HPTLC and microscopy)
- Fingerprint and bark microscopy to confirm Terminalia arjuna and exclude other Terminalia barks.
- Tannin or marker assay
- Tannins by titration or polyphenols by UV, or triterpene acids by HPLC, with the method named.
- Heavy metals
- Lead, arsenic, cadmium and mercury by ICP-MS, checked against the buyer's limits and any Prop 65 exposure targets.
- Microbiology
- Total plate count, yeast and mold, coliforms or E. coli, and Salmonella. Raw powders carry more microbial load than extracts and are often steam treated.
- Pesticide residues
- Multi-residue screen by GC-MS/MS and LC-MS/MS, required for organic material and commonly requested for conventional lots.
- Physical tests
- Loss on drying, mesh size, bulk density and extract ratio.
Storage, lots and expiry
Storage and shelf life
Keep powders and extracts sealed in lined fiber drums or foil bags in a cool, dry place away from light. Dry extracts are hygroscopic and cake once exposed to humid air, so reseal opened containers promptly. Shelf life or a retest date comes from the supplier's specification, and the marker assay is usually repeated at retest.
Lots and expiry dates
Tannin and triterpene levels vary with tree age and collection region, so record origin, method and result for each lot. Bark is often wild collected, so ask for collection documentation and keep the supplier lot traceable.
