Guduchi
Guduchi suppliers and sourcing guide
Guduchi is Tinospora cordifolia, a climbing shrub in the moonseed family (Menispermaceae) native to India, and the trade uses mainly its fleshy stem. Stems are cut, dried and milled, or extracted with water (sometimes water-ethanol) and dried to a powder. Extracts are sold by extract ratio or standardized to bitter principles or polysaccharides, and buyers specify stem material because leaf and root are also sold.

Forms and grades of guduchi
Suppliers sell different products under the same name. Specify the one you need.
Stem powder
Dried, milled stem sold by mesh size without standardization.
Aqueous extract
Water extract of the stem, dried to a powder and sold by extract ratio or with a declared bitters or polysaccharide content.
Satva (starch extract)
Traditional starch-rich sediment prepared from the stem juice, sold by some Ayurvedic suppliers.
Organic
Stem powder or extract from certified organic 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 microscopy to confirm Tinospora cordifolia stem and rule out related Tinospora species such as T. crispa.
- Marker assay
- Bitter principles, berberine or polysaccharides by a named HPLC, UV or gravimetric method, as set by the supplier's specification.
- 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
Marker levels vary with plant age, host tree and harvest season, so record the part, origin and assay result for each lot. Species substitution with other Tinospora species is a known risk, so keep identity results and retained samples.
