Eucommia Leaf Extract Powder

Leaves of Eucommia ulmoides, the hardy rubber tree native to central China, supply this eucommia leaf extract, and the bark that the tree is better known for is not used. Water extraction concentrates the soluble leaf fraction, and the liquor is dried into a green powder that disperses in water.

This is a 10:1 ratio extract milled to 80 mesh, and it carries no marker percentage. Chlorogenic acid-defined eucommia leaf extract is a separate standardized product, and the bark has its own ratio extract. This leaf extract carries no declared phenolic acid figure.

Eucommia ulmoides Identity & Plant Part

The botanical entity is Eucommia ulmoides Oliv., the only living species of the Eucommiaceae family and a tree that produces gutta-percha type rubber in its bark, leaves and fruit. The part used here is the leaf. Bark, seed and twigs are not part of this ingredient, even though the bark is the traditional drug known in Chinese materia medica as du zhong.

That bark-versus-leaf difference is the identity point buyers meet most. Leaf and bark come from one tree but are separate materials with separate extracts, and the leaf carries phenolic acids such as chlorogenic acid together with iridoids and flavonoids. A page or specification that says only eucommia extract leaves the part unstated.

Eucommia Extract vs Powder & Standardized Grades

Form	What It Is	Choose It When
10:1 Leaf Extract	Water-extracted, concentrated and dried eucommia leaf	A dispersible whole-leaf extract is wanted without a marker
Eucommia Leaf Extract 5–50% Chlorogenic Acid	Standardized leaf extract with a defined chlorogenic acid range	The specification names a chlorogenic acid figure
Eucommia Bark Extract Powder	Ratio extract of the eucommia bark instead of the leaf	The bark, not the leaf, is the target
Chlorogenic Acid 98%	Isolated phenolic acid compound	A single pure compound is required

The 10:1 ratio records how much eucommia leaf went into the extract. It states no chlorogenic acid figure, so a labelled content belongs to the standardized grade and cannot be read from the ratio. Chlorogenic acid is water soluble and travels into a water extract, but the share that reaches the dried powder depends on extraction conditions that the ratio does not describe.

The three siblings change the basis of the specification. The standardized extract adds a chlorogenic acid range with its method, the bark extract moves to another part of the tree, and pure chlorogenic acid is a single compound with no leaf matrix. A declared chlorogenic acid figure points to the standardized extract, while a plain eucommia leaf extract with no figure points here.

The color of eucommia leaf extract follows extraction time and drying, so it is a physical description of the lot and not a quality ranking.

Application Areas

Leaf Extract Capsules

Eucommia leaf extract goes into hard capsules once it has been blended with a flow aid. The dispersible powder wets quickly once the shell opens, and opaque capsules keep the green color from showing. Fill weight is worth checking early, since a fine leaf extract packs densely.

Tea-Style Instant Mixes

Eucommia leaf has a long history as an herbal infusion, so tea-style instant mixes are a natural format. The extract disperses to a hazy green-brown cup with a mild bitter edge, and roasted-grain or jasmine-style flavors are the usual match.

Compressed Tablets

The leaf extract compresses with a binder and disintegrant. Because phenolic acids can darken near iron, tablet lines check metal contact surfaces, and a film coat hides the green tint of the core while keeping the surface clean.

Powder Sachet Blends

Single-dose sachets pair the extract with fruit powders or a dispersible carrier. Particle size is matched across components, so the dense green extract does not separate from a lighter base on the filling line, and the sachet seam stays clean when little fine dust reaches it.

Formulation Notes

The powder is green with a mild grassy aroma and a bitter, slightly astringent taste carried by its phenolic acids. In water it disperses to a hazy olive-green liquid, with a little fine material settling on standing, and it does not form a clear solution.

Phenolic acids oxidize and darken in alkaline or iron-contaminated conditions, so keep the blend near neutral pH and away from iron-containing premixes. Premixing with microcrystalline cellulose keeps eucommia extract from bridging in the hopper. Once a bag is opened, press the air out before resealing, because a moisture-affected leaf extract cakes and loses its fresh green tone.
