同義語： Rhein, Rhubarb Yellow, Cassia reticulata extract, Rheum palmatum extract, Rheum officinale extract, Rheum tanguticum extract, 4,5-Dihydroxyanthraquinone-2-carboxylic acid, Monorhein.

Rhein has become a molecule of interest for B2B buyers in the pharmaceutical, nutraceutical, and cosmetic ingredient sectors. Its well-documented anti-inflammatory and antioxidant properties make it a candidate for joint health formulations, metabolic support supplements, and topical cosmeceuticals. Unlike many botanical extracts, Rhein offers a defined chemical identity, which simplifies formulation and regulatory documentation.

Rhein is an anthraquinone derivative found in the rhizomes of Rheum species (rhubarb), Polygonum cuspidatum, and Cassia species. It is produced by extraction and purification from these plant sources, yielding a high-purity compound with consistent quality. The material is typically standardized to ≥98% by HPLC, ensuring reliable performance in research and product development.

With a growing demand for clean-label and plant-derived actives, Rhein provides a synthetically independent option. Its crystalline form and solubility profile allow for easy incorporation into various dosage forms, from capsules to creams.

製品の概要と成分

Rhein (4,5-dihydroxyanthraquinone-2-carboxylic acid) is a naturally occurring anthraquinone. It is isolated from rhubarb root and other botanical sources, then purified to a high degree. The product is a single chemical entity, not a mixture, which ensures batch-to-batch consistency and predictable biological activity.

Our Rhein is manufactured under strict quality control, with each lot tested for assay, impurities, and residual solvents. It is available as a fine yellow powder, compatible with common excipients and solvents used in solid and liquid formulations.
