Isatis Indigotica Leaf Extract Powder

Isatis indigotica leaf extract is made from the leaves of the woad relative known in Chinese trade as da qing ye, and not from the root. Water extraction concentrates the soluble leaf fraction, and the liquor is dried into a green powder that disperses in water.

The extract is supplied at a 10:1 ratio and milled to 80 mesh, with no marker percentage declared. Root extracts, a marker-based root extract and a root powder of the same species are listed separately, so this leaf extract is the right line only where the leaf is the specified part.

Isatis indigotica Identity & Plant Part

The botanical entity is Isatis indigotica Fortune ex Lindl., a biennial herb of the Brassicaceae grown for its leaves and roots. The part used is the leaf. The root, sold as ban lan gen, is a separate drug and a separate product here. Several other plants are sold regionally under the name da qing ye, so the species has to be named. The leaf carries indole compounds, including indigo precursors that give woad its dye history, together with glucosinolate-derived compounds and organic acids, named here without figures.

Isatis Indigotica Leaf Extract vs Other Forms

Form	What It Is	Choose It When
10:1 Leaf Extract	Water-extracted, concentrated and dried Isatis indigotica leaf	The leaf is the specified part
Isatis Root Extract Powder	Ratio extract of the Isatis root instead of the leaf	Root-derived material is the target
Isatis Indigotica Root Extract 0.1–5% Epigoitrin	Root extract with a defined epigoitrin range	A stated root marker range is required
Isatis Root Powder	Milled dried Isatis root with no extraction	A root powder at higher inclusion is wanted

Concentration relative to the leaf is what the 10:1 ratio expresses. It is not a marker figure, and the root marker named in the table belongs to the root and cannot be carried over to the leaf.

Leaf and root are different materials in Chinese herbal practice and in trade, even though the plant is the same. This Isatis indigotica leaf extract is green and leafy in character, while the root lines are light brown and starchy. Naming the leaf on the order keeps the product from being swapped for the better-known root.

Application Areas

Leaf Extract Capsules

Isatis indigotica leaf extract goes into two-piece capsules as a green powder with a faint, grassy, slightly cabbage-like note. A flow aid in the premix prevents bridging of the fine powder, and an opaque capsule shell protects the green color from light.

Green Tea-Style Mixes

In instant mixes the extract gives a hazy green-brown liquid with a mild, grassy bitterness. Lemon, mint or jasmine-style flavors cover the leaf note, and a soluble carrier keeps the dose even from sachet to sachet.

Pigmented Tablet Blends

Tablets carry the extract at modest inclusion, and the green tint shows as speckles in a white core. A colored film coat hides it, and granulating first keeps the fine powder from sticking to the punches in humid rooms.

Leafy Gummy Premixes

Gummies add the extract to the cooked base late, and the green-brown tint suits lime, apple or herbal flavors. Heat dulls chlorophyll-type pigments toward olive, so the finished gummy shade should be checked after storage.

Powder Stick Packs

Single-serve sticks carry the extract with a soluble carrier and acid. Opaque film protects the green tone from light, and the mild leaf flavor needs only a modest sweetener to sit comfortably in a drink.

Formulation Notes

Isatis indigotica leaf extract is a green powder with a faint grassy, slightly mustard-like aroma and a mildly bitter taste. Added to water, the powder makes a hazy green-brown liquid, and a fine sediment settles on standing. The green fades toward olive with light, heat and acid.

Leaf water extracts take up moisture from the air, so weigh the Isatis indigotica leaf extract in a dry room and reseal the pack after each draw. Surface clumping and dulling of the green are early signs of uptake. For capsule work, blend a free-flowing carrier into the powder, and stir the powder into the dry base of drinks.

Plants of the woad group carry indole compounds that can oxidize to blue or brown tints over time. Keep Isatis indigotica leaf extract in sealed liners away from heat and light, and watch for a color drift at the surface of opened packs before using older stock.
