Andrographolide Powder (CAS 5508-58-7) – 98% HPLC | Natural Immune Ingredient
Product Description
Andrographolide is a labdane diterpenoid lactone isolated from the leaves and stems of Andrographis paniculata(King of Bitters, ), a medicinal plant traditionally used in Ayurveda and Traditional Chinese Medicine. It is recognized as the primary bioactive marker of the herb, responsible for its anti-inflammatory, antiviral, immunomodulatory, and hepatoprotective properties.
Compared with synthetic antibiotics, Andrographolide is marketed as a “natural antibiotic” ingredient in dietary supplements targeting seasonal immune support, upper respiratory health, and inflammatory balance. Our material is HPLC-standardized, off-white to white crystalline powder, available in 98% and 99% grades for nutraceutical and pharmaceutical use.
