Description
STANDARDISED BOTANICAL ACTIVE
Matrine — 4.0%
Matrine from Sophora flavescens root is listed at a 4.0% HPLC assay. A separate 98% matrine product has a different declared potency. Confirm the named alkaloid, companion oxymatrine result and offered-lot specification before comparing the two.

Buyer Decision Guide
Two matrine grades are traded on the same name, and they are not interchangeable. Three points decide which one a specification actually asks for.
- Assay: 4.0% matrine by HPLC, released against the batch COA.
- Companion alkaloid: oxymatrine reported separately rather than rolled into the matrine figure.
- Basis: standardised on alkaloid content, not on plant input ratio.
- Identity confirmed as Sophora flavescens root, not a mixed Sophora species.
- Particle size, moisture and heavy metals reported per batch.
- COA, specification sheet and safety data sheet accompany each shipment.
How This Grade Differs
Matrine 98% is listed separately as a higher-assay grade. Compare matrine and oxymatrine results, analytical method and required active-mass basis before changing a formulation or comparing quotations.
Compare listed products: matrine 98% grade. Review the current batch specification before substitution.
Quality and Documentation
Each lot is assayed by HPLC with oxymatrine integrated on the same run, then checked for moisture, ash, heavy metals and microbiology. Batch records and a retained sample are kept.

Frequently Asked Questions
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch named on the quotation referenced on the specification.
What physical form does Matrine Powder 4% ship in?
Off-white to pale yellow powder, milled to 98% through 80 mesh.
How is Matrine Powder 4% quantified?
By HPLC against the specification figure of 4.0%.
How do you control related substances?
Related substances are integrated on the same HPLC run used for the 4.0% assay.
Which marker is the percentage based on?
The declared figure is 4.0%, measured by HPLC; the marker basis is recorded on the batch certificate.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
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.
