In short: hawthorn is a case where you must fix two things before ordering — the plant part and the species. Leaf grades here are standardised to vitexin rhamnoside or total flavones; fruit grades are sold as ratio extracts with no marker. Two different Crataegus species also appear across the range, and one certificate carries a plant-part note that does not match its product line.

Grade comparison: hawthorn extract powder
| Your requirement | Grade to specify | Why |
|---|---|---|
| Your claim names vitexin rhamnoside | Leaf 2% Vitexin Rhamnoside | The only grade in the range that declares this specific marker |
| Your claim names total flavones | Leaf 5% Flavones | Declared as flavones by UV; confirm the plant-part note on the certificate |
| You need a non-standardised fruit base | Fruit 4:1 or 10:1 | Ratio grades with no declared marker |
| You need a stated species | pinnatifida grades | Three grades state Crataegus pinnatifida Bge.; the 5% flavones grade states Crataegus laevigata |
Buyer Decision Guide
Work through these in order — each step narrows the next:
- Start from the claim, not the percentage. Identify the marker your label or customer specification names. A grade declaring a different marker is a different product, whatever its headline number.
- Fix the assay method in writing. UV and HPLC results are not interchangeable for the same material. State the method your specification requires.
- Ask for the batch, not the sheet. A specification describes a grade; the COA describes the batch you will receive. Require the batch number on the packing list.
- Check the physical parameters too. Loss on drying and the ash determination reveal process consistency. A result far outside the representative range is worth questioning even if the marker is on target.
- Confirm mesh size against your process. Particle size affects blending, tabletting and hydration, and it can usually be adjusted if stated up front.
Qualification and COA Review
Every grade on this page is produced at the same certified manufacturing site, and each batch is released against its own certificate of analysis. When you review the COA, confirm four things: the batch number matches your order documents; the assay method is the one you specified; the marker result sits inside the declared limit; and the physical parameters are reported rather than left blank.
For first orders, requesting a retention sample alongside the shipping documents makes incoming inspection considerably easier.

Frequently Asked Questions
Why does the plant part matter so much for hawthorn?
Because the marker follows the plant part. The leaf grades in this range declare vitexin rhamnoside or total flavones; the fruit grades are sold as ratio extracts with no quantified marker at all. A specification that says only “hawthorn extract” does not tell you which of these you are buying.
Two different Crataegus species appear across the range — does that matter?
It matters for documentation. Three grades state Crataegus pinnatifida Bge. and the 5% flavones grade states Crataegus laevigata. If your registration, label or customer specification names a species, confirm which one the certificate for your batch states rather than assuming they are interchangeable.
One grade’s certificate carries a plant-part note that does not match its product line — what is that about?
The 5% flavones grade is listed as a leaf extract, while the source COA product line refers to a berry extract. That is a documentation inconsistency rather than a quality finding. It is disclosed here so it does not surface later as an unexplained discrepancy during your document review — ask for the plant part to be confirmed in writing before approving the specification.
What is the difference between vitexin rhamnoside and total flavones?
Vitexin rhamnoside is a single named flavonoid compound, whereas total flavones is a broader group measured by UV. A 2% vitexin rhamnoside grade and a 5% total flavones grade are therefore not comparable on the percentage alone — the marker definitions differ.
Is the hawthorn ratio grade a substitute for the marker grades?
No. The 4:1 and 10:1 grades declare only an extraction ratio, with no quantified marker, so they cannot support a claim that names vitexin rhamnoside or flavones. If a quantitative claim is required, a marker-standardised leaf grade is the appropriate product.
Some grades state ash and one states sulphated ash — can I compare them?
Not directly. Ash and sulphated ash are different determinations. Within this range the leaf 5% flavones grade states sulphated ash while the other grades state ash, so read the parameter name on the certificate and not just the number.
What mesh size are the hawthorn grades milled to?
All four grades are milled at 98% through 80 mesh. If your blending or tabletting process needs a different particle size distribution, state the requirement when you inquire.
How should I write the inquiry for hawthorn?
State the plant part (leaf or fruit), the marker you need named if any (vitexin rhamnoside or total flavones), the assay method you require, and your destination market. With those stated, the matching grade can be confirmed without a clarification round.
