Explore our premium grade certified active ingredients designed for global dietary supplements and pharmaceutical manufacturing.
A technical guide for procurement directors, product developers, and formulation scientists.
Diosmetin (3',5,7-trihydroxy-4'-methoxyflavone) is a key bioactive aglycone flavonoid derived via the hydrolysis of diosmin or naturally extracted from citrus fruits. In the global natural ingredients sector, Diosmetin has gained considerable prominence due to its highly efficient anti-inflammatory, antioxidant, venotonic, and cellular protective properties. It acts as a primary active metabolite in the human body when diosmin is ingested, making direct supplementation of Diosmetin a highly sought-after route to optimize bioavailability and therapeutic efficacy.
As the international dietary supplement and functional cosmetics markets evolve, manufacturing partners require more than raw powders. The demand has shifted toward micronized, highly bioavailable, and meticulously validated materials that comply with international pharmacopoeias (USP, EP, and CP). Shaanxi ShineHerb Biotech Co., Ltd. positions itself at the intersection of high-technology botanical extraction and rigid quality assurance frameworks to support global B2B procurement needs.

Understanding the demand drivers shaping the future of venotonic and microcirculatory health formulations.
The global dietary supplement sector is undergoing a profound paradigm shift. Consumers are increasingly searching for highly targeted phytochemicals with high scientific backing. Historically, Diosmin served as the baseline molecule for chronic venous insufficiency (CVI) and hemorrhoidal disease management. However, pharmacological assays indicate that Diosmin itself is poorly absorbed in the gastrointestinal tract and must be hydrolyzed by the gut microbiota into its aglycone form, **Diosmetin**, to be absorbed. Recognizing this, pioneering supplement brands are bypassing Diosmin altogether, incorporating Diosmetin directly into formulations to offer faster onset kinetics and higher clinical efficacy.
Another major trend is the integration of Diosmetin into high-end cosmetic lines. Its double mechanism of inhibiting tyrosinase (promoting skin whitening) and neutralizing reactive oxygen species (ROS) makes it a dual-action asset for anti-aging and anti-pollution topical formulations. Sourcing raw materials from verified botanical suppliers with clean pesticide-free profiles is now standard practice for global buyers.
Traditional flavonoids suffer from low solubility. Innovation focuses heavily on micronized powders (D50 < 10 microns) and phytosome carrier systems to maximize plasma concentration in human clinical settings.
Combining Diosmetin with Hesperidin, Butcher's Broom Extract, or Horse Chestnut Extract creates complete microcirculation health products, attracting premium pricing in Western Europe and North America.
Procurement departments require strict documentation proving non-irradiation, absence of ethylene oxide (EtO), low heavy metals (Pb < 3.0 ppm, As < 1.0 ppm), and gluten-free status.
Scale your brand with customized formulations, flexible manufacturing formats, and rigid regulatory adherence.
ShineHerb Biotech is not only a raw material supplier; we provide full-format customized manufacturing capabilities to turn raw Diosmetin Powder into market-ready formulations. From fine powders to convenient tablets, and from easy-to-swallow capsules to custom gummies, we manage the entire value chain.
We leverage deep regulatory insight and industrial expertise to supply product registration support docs (COA, MSDS, Allergen Statements, Non-GMO Declares, Flow Charts, Stability Studies). Our target is to fast-track your product launch while securing total peace of mind for your compliance teams.
Continuous evolution in green chemical engineering and natural product extraction technologies.
We are continuously refining the conversion parameters of Diosmin into high-purity Diosmetin using food-grade enzymatic pathways. This eco-friendly enzymatic hydrolysis eliminates harsh chemical acids, reducing carbon footprint and removing trace reaction residues.
By implementing supersonic jet milling, we control the particle size distribution of our Diosmetin Powder to a D90 < 15μm level. This micronized profile drastically elevates the dissolution rate, enabling fast dispersion in liquid formulations and improving systemic bioavailability.
Our ongoing R&D is focused on creating Diosmetin liposomes and solid dispersions. Shielding the flavonoid molecule within a lipid bilayer prevents degradation in gastric acid, achieving sustained, targeted release profiles in clinical trials.
