Description
STANDARDISED BOTANICAL ACTIVE
Paeonia suffruticosa Root Bark — 99% Paeonol
Paeonol is the phenolic marker of moutan root bark. The 99% grade is a purified compound with a characteristic crystalline form and a low melting point, both of which buyers use as a quick identity check on arrival.

Buyer Decision Guide
Paeonol is volatile and melts readily. Check the packing and the storage temperature before you commit to a bulk lot.
- Assay: paeonol 99.0% by HPLC, with related phenolics declared on the COA.
- Physical form: crystalline powder with a low melting point; caking in transit points to heat exposure.
- Odour: distinct sweet-phenolic note. Faint odour suggests the material has been over-dried.
- Solubility: soluble in ethanol, sparingly soluble in water. Confirm your vehicle before scaling.
- Storage: keep cool and sealed; paeonol sublimes slowly at elevated temperature.
- Documentation: COA, specification sheet and SDS with each batch.
How This Grade Differs
A moutan 10:1 extract is already listed. This page is the isolated paeonol at 99%, which is a different purchase: the ratio product carries the whole bark profile, this does not.
Quality and Documentation
Released on a batch certificate covering assay, related phenolics, melting range, heavy metals and microbiology.
Frequently Asked Questions
