1. Product Overview
Rhubarb Extract (derived from the dried roots and rhizomes of Rheum species, traditionally known as Da Huang) has a long-standing history in botanical pharmacopeia for supporting digestive wellness, detoxification, and internal balance. Modern phytochemical and pharmacological research has identified Emodin (a natural anthraquinone derivative) as a key bioactive marker responsible for its potent anti-inflammatory, antimicrobial, antioxidant, and metabolic-modulating properties.
Our advanced extraction and purification technologies enable us to supply a standardized grade containing 50.0% Emodin, ensuring exceptional biological activity and batch-to-batch reproducibility. For B2B formulators, contract manufacturers, and dietary supplement brands, our bulk Rhubarb Extract delivers verified HPLC documentation, strict quality assurance, and reliable performance across capsules, tablets, and specialized herbal formulations.
