Description
SINGLE-ENTITY BOTANICAL ACTIVE
Stilbene Glycoside Powder 98%
Stilbene glycoside, chemically 2,3,5,4′-tetrahydroxystilbene-2-O-beta-D-glucoside, is the marker compound used to standardise Polygonum multiflorum preparations. It is supplied here as a purified single entity at 98% assay, not as a whole-herb extract.

Buyer Decision Guide
The first decision is single entity versus extract. A Polygonum multiflorum 10:1 extract and a 98% stilbene glycoside are not interchangeable: the extract carries the full phytochemical profile, while the purified compound carries a defined marker content. State which one the formulation was built around.
The second decision is the marker basis. Stilbene glycoside is the compound used to standardise this botanical in the Chinese pharmacopoeia, so a supplier quoting only extract ratio is not answering the same question.
The third decision is documentation depth. For a purified marker, residual solvent data matters as much as the assay, because purification steps are where solvents enter the process.
Application Areas
- Standardised botanical formulations
- Antioxidant research
- Hair-care and scalp formulations
- Reference material for analytical work
Packaging and Delivery
Standard export packing is 1 kg, 5 kg or 25 kg in an inner liner with an outer fibre drum. Smaller evaluation packing is available.
Frequently Asked Questions
Is this the same as a Polygonum multiflorum extract?
No. This is a purified single compound at 98%. A 10:1 whole-herb extract contains the full phytochemical profile at a much lower marker content, and the two are used differently.
What is the chemical identity?
2,3,5,4′-Tetrahydroxystilbene-2-O-beta-D-glucoside, commonly abbreviated THSG, the marker used to standardise this botanical.
What assay is supplied?
The offered grade is 98%, confirmed on the batch-specific certificate of analysis together with the analytical method.
Are residual solvents reported?
Yes. Purification steps introduce solvents, so residual solvent data belongs on the batch certificate. Request it with the quotation.
What is the minimum order quantity?
The regular MOQ is typically 1 kg, with a small evaluation sample available before a formal order subject to stock.
