Description
STANDARDISED BOTANICAL ACTIVE
Centella asiatica Whole Herb — 90% Asiaticosides
Centella triterpenoid saponins are bought as a group rather than as a single molecule. The 90% grade is used where the label claims the total asiaticoside content, and the split between asiaticoside B and madecassoside is what buyers compare between suppliers.

Buyer Decision Guide
Ask for the individual saponin breakdown, not only the total. Two 90% lots can differ noticeably in madecassoside share.
- Assay: total asiaticosides 90.0% by HPLC, with asiaticoside and madecassoside reported separately.
- Marker basis: total saponins. State whether your specification is on total or on a single saponin.
- Colour: white to light yellow. Green tones indicate residual chlorophyll from the whole herb.
- Solubility: water-dispersible at these grades, which suits aqueous cosmetic systems.
- Heavy metals: held within cosmetic limits and reported per batch.
- Documentation: COA, specification sheet and SDS with each batch.
How This Grade Differs
The site lists whole-herb powder and a 50% asiaticoside extract. This page is the 90% grade, where the price is driven by the saponin split rather than by the extraction ratio.
Quality and Documentation
Released on a batch certificate covering total saponins, individual saponin profile, residual solvents, heavy metals and microbiology.
