Resveratrol
Changsha Huir Biological-Tech Co., Ltd supplies trans‑Resveratrol extracted from Polygonum cuspidatum, identified by CAS 501‑36‑0 and a molecular weight of 228.24 g·mol⁻¹. The product appears as a fine brown‑to‑white powder and is offered in two purity grades, 50 % and 98 % as measured by HPLC. The supplier notes that the active trans isomer is the dominant component. Bulk quantities are prepared for B2B nutraceutical and pharmaceutical formulations.
In the nutraceutical market, purity levels of 98 % to 99 % are standard for antioxidant blends, while lower‑grade material around 50 % serves as a cost‑effective bulk ingredient. Typical specifications include moisture content below 0.5 % and particle size under 200 µm, which aid in consistent solubility. The powder is stable when stored in sealed containers at 2‑8 °C, protecting it from oxidation. Such handling aligns with standard chemical export regulations from China.
The trans‑Resveratrol is incorporated into dietary supplements, anti‑aging skin creams, and research‑grade pharmaceutical intermediates. Importers such as contract manufacturers, supplement formulators, and academic labs are the main customers. The product is shipped in bulk bags or drums, subject to the buyer’s preferred Incoterm, and payment is typically arranged via T/T or L/C after a pro‑forma invoice. Prospective buyers should confirm minimum order quantities, certification documents and any required import licences before finalising the order.

Before placing an order, verify the supplier’s harbour‑tier status, request a recent Certificate of Analysis and confirm that the product complies with any relevant import regulations for phytochemicals in your destination country.
