What Is Berberine HCl 98%? Applications, Dosage, Alternatives & Specifications

Berberine, also known as Huangliansu (), is a natural isoquinoline alkaloid with the chemical formula C20H18NO4+, found in many plants across four families and ten genera, including Berberidaceae, Ranunculaceae, and Rutaceae. Berberine is mainly extracted from plants such as Coptis chinensis (Huanglian), Phellodendron amurense (Huangbai), and Berberis spp. (Sankezhen), with Coptis chinensis rhizomes containing 5%–8% berberine, making it one of the richest natural sources. Berberine Hydrochloride is the hydrochloride salt form of berberine, with CAS number 633–65–8, molecular formula C20H18ClNO4, and molecular weight 371.82. Berberine 98% refers to high-purity berberine hydrochloride products with a purity of not less than 98%, with 98% as the main specification, calculated on the dried basis. According to the Chinese Pharmacopoeia 2020 edition, the content of the extracted product of berberine hydrochloride shall not be less than 97.0%, and the synthetic product shall not be less than 98.0%. Berberine 98% products are typically refined through natural plant extraction processes, with raw materials sourced from the roots, bark, and rhizomes of Phellodendron amurense and wild Berberis spp., processed from pollution-free, pesticide-residue-free botanical materials. Berberine 98% is a yellow crystalline powder, odorless, with an extremely bitter taste, soluble in hot water, and slightly soluble in water or ethanol. Berberine is a natural pharmaceutical ingredient with a long history of use, widely applied in pharmaceuticals, health foods, and functional foods globally. In China, berberine is primarily used as an antibacterial agent for intestinal infections; in Europe and the United States, berberine is classified as a dietary supplement and regulated under food regulations. In recent years, berberine's potential in metabolic regulation has gained global attention—research shows that berberine activates the AMPK pathway, demonstrating positive effects in improving insulin sensitivity, lowering blood glucose, regulating blood lipids, and weight management.

The core active component of Berberine 98% is berberine hydrochloride, with pharmacological actions involving multiple targets and pathways:

The most important mechanism of berberine is the activation of AMP-activated protein kinase (AMPK), a key regulator of cellular energy metabolism. Once activated, AMPK promotes glucose uptake and fatty acid oxidation while inhibiting hepatic gluconeogenesis and lipogenesis. This mechanism gives berberine unique advantages in glucolipid metabolism regulation.
