Diosmin Supplier

Isolation of flavonoid glycoside from Citrus aurantium L. This greyish yellow to light yellow powder is formulation compatible. The bioactive chemical is a venotonic and vasoprotective that increases lymphatic drainage and reduces capillary permeability. Our 90% HPLC standardised specification provides for proper dosage of cardiovascular vitamins, chronic venous insufficiency treatment, and anti-inflammatory drugs. In powder form it is free from the moisture associated breakdown problems of liquid extracts, therefore has a longer shelf life and retains complete phytochemical integrity throughout your production cycle.

Products Specification

Diosmin Powder Advantages

Enhanced Bioavailability: Our micronization process decreases particle size to <80 mesh size, resulting in 35% more intestinal absorption compared to normal materials.

Exceptional stability: no hydrolysis, moisture regulated (<5% loss on drying). Shelf life of 24 months if stored properly.

Consumers desire ingredient transparency, thus Clean Label Compliant means Non-GMO, HALAL, KOSHER and ORGANIC.

Low Heavy Metal Burden: Our proprietary purification techniques consistently ensure heavy metal levels are 50% below Prop 65 threshold, lowering regulatory risk for product being sent to California.

Solvent-Free Processing Water-based extraction removes harmful solvent residues and supports your “no chemical additives” marketing claims.

​​​​​​​Diosmin Powder Benefits

 

 

Application of Diosmin Powder

Chronic Venous Insufficiency Formulas: Used as tablets and capsules at 450-600mg per day to help leg heaviness, oedema and varicose vein symptoms.

Products for Treating Haemorrhoids Topical creams and oral supplements that include hesperidin to help strengthen the walls of blood vessels and to provide relief from inflammatory pain.

Supplements for Sports: Boost microcirculation and lessen oxidative stress caused by activity when used in pre-workout mixes.

Used in anti-aging serums and under-eye treatments for its ability to strengthen capillaries and reduce redness and puffiness caused by inflammation in cosmetic skincare products.

Pharmaceutical Intermediates: Used as a raw material in the manufacture of semi-synthetic analogues of prescription vascular disease drugs.

Production flow

Step 1 Raw Material Selection: Certified organic Citrus aurantium fruits are picked at maximum maturity and tested for pesticide free status to provide a clean baseline for Diosmin Powder beginning material.

Step 2 – Aqueous Extraction: Fruits are subjected to controlled hot-water extraction at 80-95°C for 2-4 hours to optimise diosmin production and avoid heat damage of delicate flavonoid structures.

Step 3 – Filtration and Concentration: Multi-stage membrane filtration eliminates insoluble fibre and proteins, and vacuum evaporation concentrates the active chemicals to 10-15% solids.

Step 4 – Purification and crystallisation: The pH is adjusted and the mixture cooled to allow Diosmin to crystallise. Diosmin is separated from co-extracted sugars and organic acids.

Step 5 – Spray drying: The filtered solution was atomised in a nitrogen-blanketed spray drier at input temperatures of 180°C to produce free flowing powder with maintained bioactivity .

Step 6 – Quality Assurance: Each batch is tested for HPLC potency, heavy metal screening, and microbiological analysis before issuing batch-specific COA certification.
