Product Description
Emodin (CAS 518-82-1) is a high-purity natural anthraquinone monomer compound isolated and purified from the root and rhizome of Rheum palmatum L., a traditional medicinal and edible plant. With a strict 98% HPLC purity standard, Emodin possesses stable chemical structure and excellent multifunctional biological activities, including high-efficiency antioxidation, natural anti-inflammation, broad-spectrum antibacterial and lipid metabolism regulation. It is a high-value refined raw material widely applied in high-end cosmetics, functional health foods, pharmaceutical intermediates and biological scientific research.
Different from ordinary crude rhubarb extract containing multiple anthraquinones, plant fibers and miscellaneous impurities, our Emodin adopts low-temperature circulating solvent extraction and multi-stage macroporous resin purification technology, combined with repeated recrystallization refinement. The sophisticated production process thoroughly removes residual plant impurities, solvent residues and ineffective hybrid components, ensuring single and stable active ingredients. All production procedures comply with GMP purification standards, with full-index quality detection covering heavy metals, microorganisms and residual solvents, solving the problems of unstable efficacy, low purity and inaccurate dosage of crude extracts, fully meeting high-end formula R&D and industrial mass production standards.
Emodin has outstanding antioxidant activity, which can efficiently scavenge free radicals generated by human metabolism and external environmental stimulation, inhibit cellular lipid peroxidation and oxidative damage, reduce skin and body aging caused by oxidation accumulation. It effectively improves skin dullness, rough texture and premature aging problems, maintaining youthful and healthy skin and physical state.
As a natural mild anti-inflammatory ingredient, Emodin can significantly inhibit the secretion of pro-inflammatory factors, relieve internal chronic mild inflammation and skin inflammatory reactions. It effectively alleviates skin redness, swelling and sensitivity caused by external irritation, improves acne and inflammatory skin problems, repairs damaged skin barriers, and stabilizes skin microecological balance.
Emodin features excellent broad-spectrum antibacterial performance, with obvious inhibitory effects on various harmful bacteria and microorganisms. It can effectively inhibit bacterial reproduction, reduce skin infection problems, and assist in improving acne-prone and problematic skin, which is widely used in clean and soothing skincare formulas.
In health care and biochemical fields, Emodin shows good lipid-regulating and metabolic balancing effects. It can assist in regulating body lipid metabolism, reduce fat accumulation, improve internal metabolic circulation, and relieve sub-health problems caused by metabolic disorders. Meanwhile, it has certain immune regulation and body conditioning functions, helping to enhance the body’s natural defense capacity.
In pharmaceutical intermediate research, high-purity Emodin serves as a key precursor compound for the development of new anti-inflammatory, antibacterial and metabolic regulatory drugs, providing accurate and stable raw material support for biomedical research and new drug formula innovation.
Our premium Emodin product is uniform orange-yellow crystalline fine powder with delicate texture, loose and non-caking, faint natural characteristic odor and no abnormal impurities. Each batch is strictly tested by professional HPLC equipment to guarantee 98% standard purity and consistent batch quality. It features stable chemical properties and excellent formula compatibility, suitable for skincare essences, creams, health care capsules, tablets and laboratory precision experimental formulas.

FAQ
Q1: What is Emodin used for?
A: Emodin is a natural anthraquinone monomer extracted from rhubarb. It has excellent antioxidant, anti-inflammatory, antibacterial and metabolic regulation effects, widely used in high-end cosmetics, health supplements and pharmaceutical intermediate research fields.
Q2: What is the difference between Emodin and rhubarb extract?
A: Ordinary rhubarb extract is a mixed powder containing multiple anthraquinones and a large amount of impurities with unstable efficacy; our Emodin is a single 98% high-purity monomer, featuring accurate content, targeted efficacy, higher safety and better formula stability.
Q3: What are your Emodin product advantages?
A: Our Emodin adopts multi-stage resin purification and recrystallization technology, with strict 98% HPLC purity, ultra-low residual impurities and solvents, uniform powder texture and stable batch difference, meeting cosmetic, food and pharmaceutical high-end standards.
Q4: How to store Emodin correctly?
A: High-purity Emodin is sensitive to light, heat and moisture. It must be sealed and stored in a cool, dry and dark environment to prevent oxidation discoloration, moisture absorption and attenuation of active ingredients.
Q5: What does qualified 98% Emodin powder look like?
