Rutin concentrate is a high-purity natural bioflavonoid concentrate extracted and refined from natural plant raw materials, mainly sourced from Sophora japonica flower buds and tartary buckwheat. Also known as rutoside or vitamin P, its chemical name is quercetin-3-O-rutinoside with the CAS number 153-18-4. Different from ordinary crude extracts, rutin concentrate is processed through modern low-temperature extraction, membrane filtration and high-purity purification technologies, featuring stable content, low impurities and high biological activity. It is a core bulk raw material widely used in global nutraceutical, pharmaceutical, functional food and cosmetic industries, and conforms to international food-grade and pharmaceutical-grade production standards.
In international trade, rutin concentrate has unified mainstream grading standards based on HPLC detection, which is the core inspection standard for cross-border procurement and customs clearance. The mainstream commercial specifications include 95% rutin concentrate and 98% high-purity rutin concentrate, and customized concentration ratios such as 4:1 and 10:1 are available for special industrial demands. All qualified rutin concentrate products need to pass HPLC content testing, heavy metal detection, microbial limit testing and residual solvent inspection, and can provide complete COA, MSDS, ISO and other certification documents to meet global buyer quality audit requirements. Regular industrial packaging is 25kg/drum with double-layer food-grade plastic sealing inside and cardboard drum outside, supporting FCL and LCL bulk transportation.
Rutin concentrate owns three core verified biological activities, which are the key reasons for its stable demand in the global market. Firstly, it has excellent antioxidant activity, which can effectively eliminate free radicals, reduce oxidative damage to human cells, and delay aging. Secondly, it has significant anti-inflammatory properties, relieving mild inflammatory reactions of the body. Most importantly, rutin concentrate can strengthen capillary vessel walls, improve vascular toughness and permeability, effectively maintain cardiovascular and cerebrovascular health, and assist in improving venous circulation problems. Compared with synthetic flavonoid ingredients, natural plant-based rutin concentrate has higher safety, no side effects, and is compliant with clean label trends in European and American markets.
As a versatile natural plant extract raw material, rutin concentrate covers multiple high-demand downstream industries worldwide. In the nutraceutical industry, it is widely added into vascular health supplements, antioxidant capsules and daily nutritional tablets. In the pharmaceutical industry, it is used as a key auxiliary raw material for cardiovascular and microcirculation regulatory drugs. In the functional food industry, it is applied in functional beverages, health care tea and fortified nutritional foods. In the cosmetic industry, it is added into anti-aging and soothing skin care products to resist oxidative skin damage. With the global upgrade of health consumption awareness, the market demand for high-purity natural rutin concentrate maintains steady annual growth, becoming a hot-selling plant extract product in international bulk trade.
