Swertiamarin (CAS 17388-39-5) – High-Purity Iridoid Glucoside from Swertia Herb
Production Introduction
Swertiamarin is a naturally occurring iridoid glucoside isolated from the aerial parts of Swertiaspecies (Gentianaceae). It presents as a white to off-white crystalline powder, slightly hygroscopic, with a distinctly bitter taste. As a classic Traditional Chinese Herbal Extract component, it has long been used for cholagogue, stomachic, antispasmodic and analgesic purposes in phytomedicine.
Our Swertiamarin is supplied at ≥96% / ≥98% HPLC, suitable for pharmaceutical R&D, natural health product formulation, cosmetic antioxidant systems, and botanical reference standard use.

FAQ
Q: Is Swertiamarin the same as sweroside?
A: No. Both are iridoid glucosides from Swertia/Gentianafamily, but different aglycones and CAS numbers. Swertiamarin = CAS 17388-39-5.
Q: What solvent should I use for dissolution?
A: Methanol, ethanol or DMSO are recommended; poorly soluble in chloroform and petroleum ether.
Q: Can you provide a Certificate of Analysis?
A: Yes — every batch ships with COA (HPLC purity, heavy metals, solvents residue on request).
