Diosmin

Diosmin is a flavone glycoside, the 7-rutinoside of diosmetin, that occurs naturally in citrus peel and is produced commercially from hesperidin extracted from citrus fruit. Nustras supplies it as a fine powder, a flavonoid ingredient for the supplement and pharmaceutical sectors.

Diosmin is formulated into flavonoid and citrus-bioflavonoid supplements in tablet and capsule form, into pharmaceutical preparations in markets where it is registered as an active ingredient.

The material is a greyish-yellow to light yellow, fine, hygroscopic powder, practically insoluble in water and ethanol. Assay, loss on drying and related substances are standardised to specification and determined by HPLC and the compendial tests of the applicable pharmacopoeia; identity is confirmed by infrared spectroscopy and HPLC retention against a reference, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis. CAS 520-27-4, molecular formula C28H32O15, molecular weight 608.5.

Nustras supplies diosmin in bulk commercial quantities, in sealed packaging and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. Diosmin is sold as a supplement ingredient in some markets and as a registered pharmaceutical active in others; buyers confirm the permitted status, grade and claim for their application.
