Centella Extract Powder

Gotu kola gives this centella extract its identity: the leaves, petioles and thin stems of Centella asiatica (L.) Urb., the creeping carrot-family herb, and not the root. Water extraction concentrates the soluble fraction of that aerial material, and the liquor is dried into a light brown powder.

The extract ratio is 10:1, the powder is milled to 80 mesh, and it is water dispersible. It carries no triterpene figure, so it differs from the triterpene-defined gotu kola extract, from the plain herb powder and from asiatic acid, the purified single triterpenoid sold as a separate product.

Centella Identity & Plant Part

Centella asiatica is a low, creeping plant of the carrot family, sold as gotu kola and as Indian pennywort. The part used here is the aerial portion: leaves, petioles and thin stems. Roots are not part of this extract. Two name confusions are common in trade. Hydrocotyle species are also called pennywort and have round, shield-like leaves, and brahmi in Indian trade names refers to Bacopa monnieri as well as to this plant. The characteristic constituents are triterpenoid saponins and their sapogenin forms, together with phenolic acids and flavonoids. They are named here as families only, because this centella extract carries no triterpene claim.

Centella Extract vs Powder & Triterpene Grades

Form	What It Is	Choose It When
10:1 Centella Extract	Water-extracted, concentrated and dried aerial parts	A whole-herb extract in a dispersible powder
Gotu Kola / Centella asiatica Extract 8% total triterpenes	Extract defined by total triterpene content	A triterpene-defined grade is specified
Gotu Kola (Centella) Powder	Dried aerial parts milled without extraction	Herb fiber and bulk are wanted
Asiatic Acid 98%	Purified single triterpenoid acid	A single-compound ingredient is specified

A 10:1 ratio tells a buyer how much dried herb was used per unit of extract, not how much triterpene the powder holds. Two lots at 10:1 can differ in saponin content because the herb itself varies. When a formula names a triterpene level, use the defined grade in the table. When it calls for a gotu kola extract built on the herb as a whole, with no single compound driving the specification, the centella extract at 10:1 fits. The powder adds herb fiber and bulk. The purified acid holds one compound out of the many in the plant, so it cannot stand in for the herb.

Application Areas

Capsules for Herb Extract Blends

Centella extract powder fills hard capsules as a herbal extract, alone or in botanical blends. The powder is fine and can flow slowly, so check fill-weight uniformity on the machine. Its saponins make the dry powder lightly foamy when it is poured into water.

Stick Packs with Green Notes

In drink sticks, the extract gives a light brown, slightly hazy dispersion with a green, earthy taste and mild bitterness. Mint, citrus and ginger flavors pair well with that profile, and sweeteners soften it. Dissolve in a small volume first to avoid clumping.

Tablet Granulation

For tablets, the extract is blended with a dry binder and disintegrant or wet-granulated with other herbal extracts. The saponins can foam during wet granulation, so low-shear mixing or antifoam handling helps keep the granule consistent from batch to batch.

Gummies with Herb Extracts

In gummies, add the extract after the cooked mass cools, which protects flavor. Expect a green-brown tint in light-colored bases, and use a berry or citrus flavor system that hides the earthy taste without fighting the herb’s bitterness.

Bars and Bites with Herb Extract

Centella extract powder works in the dry mix of bars and bites, where chocolate, cocoa or nut flavors cover its green taste. It adds little bulk compared with milled gotu kola herb, but its tint carries into pale binders, so check color on the finished bar.

Formulation Notes

The powder is light brown with a grassy, earthy aroma and a lightly bitter taste. Because the herb contains saponins, a water dispersion of this centella extract can foam when stirred or shaken, which matters in bottling lines and in shaker-style drink mixing. A fine, slightly hazy dispersion is normal, since insoluble herb matter does not dissolve.

In dry blends, premix with a larger powder fraction before adding to a mixer to avoid lumps and static. The extract takes up water from humid air, so weigh it quickly and keep the container sealed between uses. Once opened, store the remainder tightly closed, away from light and heat, and press out excess air before resealing the liner.
