Rhubarb Extract

Synonyme: Rheum palmatum extract, Chinese Rhubarb extract, Da Huang extract, Rheum officinale extract, Rhubarb root extract, Rheum tanguticum extract.

Rhubarb Extract is a standardized botanical concentrate derived from the dried rhizome and roots of Rheum species, primarily Rheum palmatum, Rheum tanguticum, and Rheum officinale. Known as Da Huang in Traditional Chinese Medicine, rhubarb has been used for over two millennia as a potent purgative and detoxifying agent. The extract captures the plant’s rich chemistry, offering a concentrated source of bioactive compounds for modern applications.

The primary bioactive constituents are anthraquinones, including emodin, rhein, chrysophanol, and physcion, along with stilbenes such as resveratrol and rhaponticin. These compounds contribute to the extract’s laxative, antimicrobial, and anti-inflammatory properties. The anthraquinone profile is often standardized to ensure consistent potency, making it a reliable ingredient for dietary supplements and pharmaceutical research.

Standardized to ≥98% total anthraquinones (HPLC), Rhubarb Extract is widely used in digestive health supplements, weight management formulas, and topical preparations. Its well-documented stimulant laxative effect is attributed to emodin and rhein, which promote intestinal motility. Additionally, the presence of resveratrol offers antioxidant benefits, appealing to formulators targeting healthy aging.
