Burdock Seed Extract Powder

The seeds of Arctium lappa, the great burdock, called niubangzi in Chinese herbal practice, are the only plant part behind this extract. The seeds are extracted in water, concentrated and dried to a light brown powder. Roots, leaves and the spiny burr casing are not used.

This burdock seed extract is a 10:1 ratio extract with no marker assay and no arctiin figure. The powder is milled to 80 mesh and disperses in water. An arctiin-standardized extract, a burdock root extract and a milled seed powder are separate products.

Arctium lappa Seed Source & Identity

The botanical entity is Arctium lappa L., a biennial of the daisy family, Asteraceae, native to Europe and Asia. The part used is the seed, a small, grey-brown, wedge-shaped achene taken from the dried burr. The root, which is a food vegetable, and the leaves are not part of this burdock seed extract.

Seed and root of the same plant are different raw materials with different chemistry. The cocklebur, Xanthium, has a similar spiny fruit but belongs to another genus, and lesser burdock, Arctium minus, is a separate species whose seed is occasionally mixed into lots.

The seed carries the lignans arctiin and arctigenin, together with caffeic acid derivatives and a fixed oil.

Burdock Seed Extract vs Related Forms

Form	What It Is	Choose It When
10:1 Burdock Seed Extract	Water extract of burdock seed, ratio-defined	A whole-seed extract profile without a marker figure is needed
Burdock Seed Extract 10–40% Arctiin	Standardized extract of the same seed with a defined arctiin range	The specification names an arctiin figure
Burdock Root Extract Powder	Water extract of the burdock root, a different part	The brief is root-based
Burdock Seed Powder	Dried, milled seed, no extraction	Whole-seed material with oil and fibre is wanted

The 10:1 ratio measures seed going into the burdock seed extract. It is not an arctiin assay. Arctiin is only moderately soluble in water and dissolves better in alcohol, so a water extract of the seed is not an arctiin product, and the standardized extract in the table is built differently.

The four rows are four specification bases: a ratio extract of the seed, a lignan-standardized extract, a root-based extract and a milled seed.

Application Areas

Capsules for a Seed Extract

Burdock seed extract fills hard capsules after a flow check at 80 mesh. Seed extracts that keep some residual oil can feel slightly tacky, so keep the filling room cool and the hopper covered. For burdock seed, add a glidant only where bridging appears, and check fill weight at the start of each run.

Tablets with Oil-Tolerant Excipients

Residual seed oil can interfere with binding, so tablets need a dry binder and a lubricant added late in the blend. For burdock seed, compare hardness at pressing and after a week of storage. A film coat covers the light brown core and slows moisture pickup.

Tea-Style Instant Sticks

Burdock seed is traditionally prepared as a decoction, so tea-style sticks suit the extract. It disperses to a tan, slightly hazy cup with a bitter-leaning taste. Ginger, licorice-style or citrus-peel flavours balance it, and a taste test at the planned dose sets the fill weight.

Fibre-Carrier Sachets

Sachets carry burdock seed extract in a sugar or fibre carrier. Sieve the powder into the carrier before filling to spread the tan tone evenly, and run a dose-uniformity check at the start, middle and end of the filling run.

Granola-Style Bar Mixes

Bar recipes work best when the burdock seed extract is dispersed through the dry mix before binding. The bitter, nutty note suits cocoa, date and seed bars, and a taste trial after a week shows how it develops during storage.

Formulation Notes

Burdock seed extract is a light brown powder with a mild, nutty smell and a bitter taste. In water it forms a tan, slightly turbid dispersion, and a thin film of seed oil may collect on the surface of a still drink. Lignans in the seed are only partly water soluble, so some of the haze is fine suspended material.

Make a smooth paste with a little water, then dilute, if the burdock seed powder balls up when added dry. In a dry blend the burdock seed extract is best introduced as a sieved premix rather than poured in whole. For burdock seed, close the liner after weighing and keep the opened drum dry, out of direct heat and away from washdown areas.
