Bulk Hawthorn Leaf and Flower Extract for Supplement Manufacturing
Hawthorn leaf and flower extract is a dry powder made from the flowering tops or leaves of hawthorn (Crataegus species), a rose family shrub. It is usually standardized to flavonoids such as vitexin, measured by HPLC. We supply it in bulk to supplement brands, contract manufacturers, and formulators.
A flavonoid standardized extract with a USP reference
Hawthorn leaf and flower extract is easy to specify once species and plant part are fixed. It has named flavonoid markers, a USP monograph for the raw herb, and standard HPLC methods. That makes lot to lot comparison simple for buyers and quality teams.
Named flavonoid markers
Vitexin, vitexin-2''-O-rhamnoside, and hyperoside are the flavonoids most specs name. Each one is measured by HPLC against a reference standard.
A USP monograph to work from
USP Hawthorn Leaf with Flower covers C. monogyna and C. laevigata. It sets NLT 0.6% C-glycosylated flavones as vitexin and NLT 0.45% O-glycosylated flavones as hyperoside, on a dried basis.
Leaf and flower or berry
Graded extracts are usually made from the flowering tops or the leaf. The red berry is sold mostly as a whole dried powder or as an extract graded for OPCs (oligomeric proanthocyanidins).
Water and ethanol extraction
Extracts are made with water and ethanol, then dried to a powder. One published spec gives a native ratio of 6 to 8:1 with 5% maltodextrin.
Fine, free flowing powder
Spec sheets call for a brownish yellow powder with NLT 95% through 80 mesh. Bulk density runs about 0.40 to 0.60 g/mL, which suits capsule filling and tableting.
Species named on the spec
Several Crataegus species are traded. European supply uses C. monogyna and C. laevigata, while at least one published leaf extract spec names the Chinese species C. pinnatifida.
Where formulators use hawthorn leaf and flower extract
This extract fits measured formats where fill weight and serving size are controlled, including:
- Capsules
- Compressed tablets
- Single ingredient powders
- Multiple ingredient botanical blends
- Stick packs and sachets
- Powdered drink mixes, after taste trials
- Tea blends, using cut leaf and flower
- Private label programs
Plan fill weights from the confirmed assay on each COA. A vitexin grade and a total flavonoid grade measure different things, so recalculate your serving math whenever you change grade or marker.
What to check before you buy hawthorn extract
Two powders sold as hawthorn extract can differ in species, plant part, marker, and carrier. Review these points together, and ask for lot documents before you approve a supplier.
Species on every document
Confirm the Crataegus species on both the specification and the certificate of analysis (COA). The USP monograph names C. monogyna and C. laevigata, so a C. pinnatifida lot falls outside it.
Plant part
Ask whether the extract comes from leaf with flower, leaf only, or berry. USP labeling calls for the plant parts to be named, and each part has its own marker profile.
Marker and method
Ask which compound the grade refers to: vitexin, vitexin-2''-O-rhamnoside, total flavonoids, or OPCs. Then confirm the method (HPLC or UV) and whether results are on a dried or as is basis.
Carrier and its source
Some extracts include a carrier such as maltodextrin. Ask for its name, percentage, and source, such as corn.
Contaminant limits
Check heavy metals by ICP-MS, microbial limits by USP methods, pesticide residues, and residual ethanol. Compare each limit with your own finished product specification.
Origin
Ask for the country of origin. Bulk listings name China for leaf extracts and Hungary, Romania, Bulgaria, and Poland for European hawthorn.
Label math: If your label lists vitexin or flavonoids per serving, base the number on each lot's measured assay and your own finished product testing. Name the species and plant part on the label too, because the marker profile depends on both.
Typical specification for hawthorn leaf and flower extract
These values reflect the common 1.8% vitexin grade. Final figures come from the specification sheet and COA for your lot. NLT means not less than, and NMT means not more than.

Storage and handling for bulk hawthorn extract
Botanical extracts hold their quality when they stay sealed, dry, and out of light. The USP monograph for the herb calls for a well closed container, protected from light.
Keep it sealed
Close the inner liner after each use and press out the air. Extract powders pick up moisture from the air and can cake when left open.
Store cool and dry
Keep bags off the floor in a dry room, away from heat sources. Follow the temperature range on the spec sheet.
Keep away from light
Leave the powder in its original opaque packaging. Light and heat can shift color and assay over time.
Rotate stock
Record the lot number and retest date for each bag. Send older lots to production first.
Hawthorn extract buyer FAQ
Quick answers to the questions procurement and quality teams ask most.
What is the difference between hawthorn berry and hawthorn leaf and flower?
They are different plant parts with different marker profiles. Leaf and flower material is the usual base for flavonoid graded extracts such as vitexin grades. The berry is sold mostly as a whole dried powder or as an OPC extract.
What is hawthorn extract standardized to?
Leaf and flower extracts are usually standardized to vitexin, often at 1.8% or 2%, or to total flavonoids. Berry extracts are more often graded for OPCs. Check which compound and which method your COA reports before you compare prices.
Which Crataegus species are used for hawthorn extract?
European supply uses Crataegus monogyna and C. laevigata, the two species in the USP monograph. Some leaf extracts made in China use C. pinnatifida. Ask for the species on the spec and COA.
Is there a USP standard for hawthorn?
Yes. USP publishes monographs for Hawthorn Leaf with Flower and its powdered form. They name the accepted species, set flavonoid minimums, and ask labels to state the plant parts used.
What is the difference between vitexin and vitexin-2''-O-rhamnoside?
They are related flavonoids. Vitexin-2''-O-rhamnoside is vitexin with an extra sugar attached. A spec may name either one, so make sure two quotes refer to the same compound.
What documents can I get with an order?
A certificate of analysis (COA) and a specification sheet ship with every order. An allergen statement and a safety data sheet may also be available, depending on the lot in inventory. Contact us to request them.
Can I get a sample before a bulk order?
You can request one by choosing sample options on the quote form. We will confirm availability, size, and timing.
How should I store an opened bag?
Close the liner, press out the air, and keep the bag in a cool, dry place away from light. Use the powder within the shelf life shown on the COA.
