Mulberry Leaf Extract Powder

Leaves of Morus alba, the silkworm tree, are the single plant part behind this mulberry leaf extract. Water extraction concentrates the soluble leaf fraction, and the liquor is dried to a 10:1 powder. Ripe fruit, twigs and root bark belong to other mulberry products and are not part of this one.

The 10:1 ratio carries no 1-deoxynojirimycin percentage. The powder is ground to 80 mesh and water dispersible. A DNJ-graded mulberry leaf extract and the fruit and root bark extracts are separate products, and the leaf is a different raw material from the fruit.

Morus alba Leaf Identity & Plant Part

The botanical entity is Morus alba L., a deciduous tree of the mulberry family, Moraceae. The part used is the dried leaf, the same leaf that is the traditional food of silkworms. Fruit, twigs and root bark are not added to this mulberry leaf extract.

Mulberry leaf carries the iminosugar 1-deoxynojirimycin, known as DNJ, together with flavonoid glycosides and chlorogenic-type phenolics. A specification that gives only the common name does not show which part is used, so the leaf is named here. Leaf material also changes with the season and with whether the leaf was cut early or late, which is why the ratio alone cannot describe the composition.

Leaf Extract vs Fruit & Standardized Grades

Form	What It Is	Choose It When
10:1 Mulberry Leaf Extract	Water-extracted, concentrated and dried M. alba leaf	A dispersible leaf extract without a marker is wanted
Mulberry Leaf Extract 1–5% DNJ	Extract with a defined DNJ range	The specification names a DNJ figure
Mulberry Fruit Extract Powder	10:1 water extract of the fruit	Fruit identity and a berry tint are wanted
Mulberry Root Bark Extract Powder	10:1 water extract of the root bark	Root bark identity is required

On a mulberry leaf extract, the 10:1 is a concentration ratio of the starting leaf. It does not state a DNJ figure, and a buyer who has to declare DNJ on a label needs the graded extract, not the ratio extract.

The ratio extract suits tea-style mixes and capsule blends where leaf identity matters more than a marker number. The fruit and root bark extracts come from other mulberry parts with their own chemistry, so they are not interchangeable with the leaf even though all three share a species.

Application Areas

Instant Leaf-Tea Powders

Instant tea powders use mulberry leaf extract as a dissolvable alternative to leaf bags. A mild herbal infusion forms without leaf fragments, and lemon or mild sweetener is added to cover the grassy edge. Mulberry leaf extract stirs in more easily than loose leaf, and the tea-style cup stays free of sediment.

Herbal Capsule Blends

Capsule blends place the extract with other leaf and root extracts. The fine powder is light and slightly hygroscopic, so humidity at the filling station is controlled, and a flow aid is added for fast machines. A trial capsule run shows quickly whether the mulberry leaf extract needs a binder to avoid dust and static at the hopper.

Flavored Powder Sticks

Sticks combine the leaf extract with sweetener and a flavored carrier. Because DNJ is a polar compound and does not add taste, flavor in the stick comes from added flavors, while the extract adds body and a leafy note.

Plain Tablet Cores

Tablet cores take mulberry leaf extract with binders and a protective coating. The soluble solids soften in humid storage, so the core is film-coated, and hardness is checked after the tablets have aged for a set period.

Formulation Notes

The powder has a mild grassy, tea-like aroma and a slightly bitter, astringent taste. In water it disperses to a brown to green liquid that darkens as it stands. Leaf phenolics react with iron, so stainless equipment is preferred, and long hot holds deepen the color.

Premix the extract with a measured part of the base before the main blend to prevent lumps. The soluble solids pick up moisture and cake in an open pack. After opening, press out the air, reseal the liner firmly and store the container in a cool, dry place away from sunlight.

For tablets, the leaf extract is granulated or blended with a dry binder, and compression force is set by trial because soluble leaf solids harden a tablet quickly. In ready-to-drink trials, the mulberry leaf extract should be tested for sediment after a week of cold storage, since leaf tannins and proteins settle slowly as a pale haze. A light acid such as citric acid keeps the infusion clear for longer, though it also shifts the taste toward tart.
