Mulberry Root Bark Extract Powder

The inner bark of the root of Morus alba, the white mulberry, is extracted in water and dried to give this mulberry root bark extract powder. Water extraction concentrates the soluble fraction of the bark, and the result is a fine, water-dispersible powder. The fruit, leaf and twig of the same tree are separate materials and are not part of the starting material.

The product is a 10:1 ratio extract with no marker figure, milled to 80 mesh. The plain milled root bark is the unextracted form of the same material, and the fruit and leaf extracts of the tree are different products with different chemistry.

Mulberry Root Bark Identity & Plant Part

The species is Morus alba L., the white mulberry, family Moraceae. The part used is the root bark: the root is dug, the thin outer cork is scraped away, and the pale inner bark is dried. This is the material known in Chinese herbal practice as sang bai pi and in pharmacopeial trade as Cortex Mori. The wood of the root, the stem bark, the twig, the fruit and the leaf are not included in this mulberry extract.

The bark chemistry differs from the rest of the tree. Literature on the species describes prenylated flavonoids and Diels-Alder type adducts such as the kuwanons in root bark, while the fruit carries anthocyanins and the leaf carries iminosugars. That is why a purple colored mulberry extract belongs to the fruit and not to the bark. Trade names also blur the genus: Morus nigra and Morus rubra are separate species that appear under the same mulberry label.

Mulberry Extract vs Powder & Other Parts

Form	What It Is	Choose It When
10:1 Root Bark Extract	Water-extracted, concentrated and dried mulberry root bark	A dispersible bark extract is wanted without a marker figure
Mulberry Root Bark Powder	Milled dried root bark with no extraction step	Fiber and the whole bark profile are acceptable
Mulberry Fruit Extract Powder	10:1 extract of the berry of the same tree	The fruit, not the bark, is the required part
Mulberry Leaf Extract Powder	10:1 extract of the leaf of the same tree	The leaf, not the bark, is the required part

The 10:1 figure is a concentration ratio of the starting material: it says how much root bark went into each part of extract, and it says nothing about how much of any one compound came out. Against the milled bark, the extract removes much of the insoluble fiber, so it fills a capsule or a stick pack at a smaller weight and leaves less sediment in a drink. Against the fruit and leaf extracts, the difference is the part, and a buyer should name the part in every inquiry.

Application Areas

Capsules and Coated Tablets

Mulberry root bark extract fills capsules at a lower weight than milled bark, because the extract drops much of the fiber. For tablets, a dry binder holds the bark extract together, and a film coat limits moisture pickup and covers the bitter, astringent taste.

Powder Stick Packs

Sticks take the dispersible bark extract in tea-style and herbal drink mixes, where an earthy, slightly bitter note is expected. Sweeteners and warm spice flavors cover the edge, and weight-based filling keeps each stick consistent from lot to lot.

Instant Herbal Drink Powders

Instant herbal powders use the extract in hot water, where it disperses into a hazy tan to brown liquid. Pre-wetting it with a small amount of warm water prevents floating lumps, and a short stir gives an even drink.

Gummy and Bar Premixes

Gummies and bars accept the extract at gram-level inclusion, where the dark tone and mild bitterness disappear into cocoa, caramel or spice bases. Add it to a gummy mass after the cook, and blend it into bar dry mixes before the binder.

Formulation Notes

The powder has an earthy, slightly woody odor and a bitter, astringent taste. Its color is a tan to brown tone and not the purple of the berry. In water it forms a hazy dispersion, because the fibrous and resinous parts of the bark do not fully dissolve. Like most water-extracted bark extracts it takes up moisture from the air, and a damp mulberry root bark extract powder darkens and clumps before it loses flow.

Pass the powder through a sieve before use, and premix it with a dry bulking carrier for small inclusions so that the bark extract is spread evenly through capsule and stick fills. For drinks, wet it with a little cool water first, then dilute. Reseal the liner after every draw, store the drum away from humidity and strong odors, and check each new lot against a retained sample for shade and aroma.
