Description
STANDARDISED BOTANICAL ACTIVE
Ursolic Acid 99% — Pentacyclic Triterpene
Ursolic acid is a pentacyclic triterpenoid supplied at monomer purity for cosmetic and formulation work. At 99% it is a purified single compound, not a leaf extract, so the comparison most buyers make is against oleanolic acid rather than against plant ratio products.

Buyer Decision Guide
Ursolic and oleanolic acid are isomers that co-occur in the raw material and are separated during purification. The ratio is the first thing to check on the COA.
- Assay: ursolic acid 99.0% by HPLC, with oleanolic acid reported as the principal related substance.
- Source note: the botanical origin is stated on the batch certificate and varies by production run.
- Solubility: insoluble in water, soluble in ethanol. Confirm your solvent system before ordering bulk.
- Appearance: white crystalline powder. Yellowish lots usually carry residual chlorophyll.
- Residual solvents: declared per lot against the limits of the destination market.
- Documentation: COA, specification sheet and SDS with each batch.
How This Grade Differs
Two ursolic-bearing extracts are already listed, at 20% and 2%. Those are extracts; this page is the isolated triterpene at monomer purity, which is a different purchase with a different price basis.
Quality and Documentation
Released on a batch certificate covering assay, related substances, residual solvents, heavy metals and microbiology.
Frequently Asked Questions
How is Ursolic Acid Powder 99% quantified?
By HPLC against the specification figure of Ursolic acid 99.0%.
How does the material behave in your process?
It is supplied as White to off-white crystalline powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
What purity window can you hold batch to batch?
Ursolic acid 99.0%, verified by HPLC on every lot.
How is lot traceability handled?
Each lot keeps batch records and a retained sample, and the certificate for the shipped lot carries the same batch reference used in the quotation.
What shelf life and storage conditions apply?
Two years when stored properly, kept sealed in a dry place away from light and heat.
Can I get a sample before placing the order?
Yes. An evaluation sample is normally available before a formal order. Sample quantity, courier account and destination are confirmed at the time of request.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
