Description
STANDARDISED BOTANICAL ACTIVE
Leonurus japonicus Herb — 99% Stachydrine HCl
Stachydrine hydrochloride is the alkaloid marker of Leonurus japonicus. At 99% it is a purified salt rather than a herb extract, which changes both the dosing and the documentation a buyer should expect.

Buyer Decision Guide
Confirm whether the quotation is for purified stachydrine salt or for a herb extract with a declared stachydrine content. The two are priced on completely different bases.
- Assay: stachydrine hydrochloride 99.0% by HPLC, with the salt form stated explicitly.
- Salt basis: hydrochloride. If your specification is on the free base, convert before comparing prices.
- Appearance: white to off-white powder. Yellowish lots suggest residual plant pigment.
- Solubility: freely water-soluble, which suits beverage and tablet applications.
- Moisture: hygroscopic; seal the pack and specify humidity control at your plant.
- Documentation: COA, specification sheet and SDS with each batch.
How This Grade Differs
A Leonurus herb extract is already listed. That product is a herb extract; this page is the purified alkaloid salt at 99%, and the salt form is the first thing to check on the COA.
Quality and Documentation
Released on a batch certificate covering assay, salt form, related alkaloids, residual solvents, heavy metals and microbiology.
