Eucommia Bark Extract Powder

Bark of Eucommia ulmoides, the hardy rubber tree of central China, is the only plant part behind this eucommia bark extract. Water extraction concentrates the soluble bark fraction, and the liquor is dried to a light brown powder at a 10:1 ratio. Leaves, fruit and wood are left out.

The 10:1 ratio carries no lignan percentage. The powder is light brown, ground to 80 mesh and water dispersible. The leaf extract and the plain bark powder are separate products, and eucommia leaf is a different raw material from the bark.

Eucommia ulmoides Bark Identity & Plant Part

The botanical entity is Eucommia ulmoides Oliv., the only living member of the family Eucommiaceae. The part used is the dried bark, which is stripped from the trunk and branches, scraped of its rough outer layer and dried. Leaves, fruits and wood are not added to this eucommia bark extract.

A distinctive field mark identifies the species: when the bark or a leaf is torn apart, fine, white, rubber-like threads of gutta-percha stretch between the broken edges. Leaf and bark are traded separately and differ in chemistry. Eucommia bark contains lignans such as pinoresinol diglucoside, iridoids such as geniposidic acid and aucubin, and chlorogenic-type phenolic acids.

Eucommia Extract vs Powder & Standardized

Form	What It Is	Choose It When
10:1 Eucommia Bark Extract	Water-extracted, concentrated and dried E. ulmoides bark	A dispersible bark extract without a marker is wanted
Eucommia Leaf Extract Powder	10:1 water extract of the leaf	Leaf, not bark, is the required source
Eucommia Bark Powder	Dried, milled bark	Bark fiber and rubber-like threads are acceptable
Pinoresinol Diglucoside 98%	Single purified lignan glycoside	A pure compound is required, not a plant extract

The 10:1 on this eucommia bark extract counts ten parts of dried bark against one part of powder. It gives no lignan figure, so a buyer who has to declare pinoresinol diglucoside needs a defined ingredient, not the ratio extract.

The ratio extract suits blends that want eucommia bark identity in a dispersible form. The leaf extract is a separate raw material, the milled bark keeps its fiber and rubbery threads, and the pure compound is a chemical reference rather than a bark extract.

Application Areas

Capsule Blends for Bark Extracts

Capsule blends place eucommia bark extract with other bark and root extracts. The powder is light brown, fairly free-flowing and mildly hygroscopic, so a trial run confirms fill weight. Humidity at the filling station is held low to avoid sticking.

Plain Tablet Cores

Tablet cores take the extract with a dry binder. The lignan and phenolic content darkens slightly with moisture, so tablets are dried before coating. A film coat hides the brown tone and protects the soluble solids during storage.

Tea-Style Instant Sticks

Instant sticks use eucommia bark extract as a dissolvable alternative to steeped bark. The cup is amber with a mild woody, faintly bitter taste. A small amount of sweetener or a roasted-grain flavor rounds it out, and hot water brings out the flavor more fully.

Dark Herbal Gummy Mixes

Gummy mixes accept the extract once the cooked base has cooled. The brown color suits tea, caramel or spice flavors, and the bitter edge limits the dose in mild bases. Fruit acid sharpens the taste, so it is dosed after the extract is dispersed.

Formulation Notes

The powder is light brown with a faint woody aroma and a mildly bitter, slightly astringent taste. In water it disperses to an amber, lightly hazy liquid. Phenolic acids react with iron, so stainless equipment is preferred, and long hot holds darken the color.

To prevent lumps, mix the powder into a portion of the dry base first and then add it to the main blend. Soluble bark solids draw water from the air, so a pack left open for a shift starts to clump. After opening, press out the air, close the liner tightly and store the drum in a cool, dry place away from heat.

Because water extraction leaves the insoluble rubber-like threads behind, the powder does not stretch or smear, which keeps it simple to handle. A sensory trial at the planned dose confirms the taste is acceptable in the finished product. Trials with eucommia bark extract in a tea-style stick should compare a short and a long steep, because the amber color and the mild bitterness both deepen noticeably when hot water stands on the powder for several minutes.
