Import Diosmin — Buy in Bulk from Supplier in China

Diosmin is a naturally occurring flavonoid glycoside derived from citrus peel, specifically from hesperidin through enzymatic hydrolysis. This product is offered as a crystalline powder with a minimum purity of 95% by HPLC, appearing as a pale yellow to off-white fine powder. The supplier states it is produced for use in dietary supplements and pharmaceutical formulations, with no added fillers or excipients.

The compound is chemically identified as 7-O-rhamnoglucoside of hesperetin, with a molecular weight of 608.5 g/mol. Standard assay methods follow USP or Ph.Eur. guidelines, with typical impurities including hesperidin (under 2%) and other citrus flavonoids. The product is not synthetic; it is extracted and purified using solvent-based techniques, with ethanol and water as primary solvents. The final product is dried under vacuum to preserve thermal sensitivity.

Buyers include manufacturers of venous health supplements, nutraceutical brands, and API formulators targeting circulatory support products. The product is typically encapsulated in softgels or compressed into tablets at dosages of 450mg to 900mg per unit. Trade terms are negotiable, with minimum order quantities starting at 1 kilogram. Packaging is in double-layered, food-grade polyethylene bags inside sealed drums, with desiccant. Export documentation includes COA, SDS, and origin certificates.

Highchem Co., Ltd. is listed as a supplier based in Yubei District, Chongqing, and Bozhou, Anhui Province, China. The profile indicates the company operates as an importer and supplier of flavonoid compounds, but provides no information on manufacturing capacity, facility certifications, or production methods. The trust tier is 'harbor', and no response rate or average reply time is recorded, suggesting limited buyer interaction history on the platform.

The listing claims compliance with ISO and FSSAI standards, but no certificate numbers or audit reports are provided. The supplier does not disclose whether it manufactures the compound in-house or sources it from third-party producers. No information is given on batch traceability, quality control procedures, or stability testing. Buyers must request full documentation before placing an order, as the profile lacks verifiable production or testing data.
