Dipsacus Root Extract Powder

Dipsacus Root Extract Powder is produced from the dried root of Dipsacus asper Wall. ex DC., the accepted botanical source associated with Dipsaci Radix and Xu Duan. The root is extracted, concentrated, dried, and milled into a light brown to brown powder for dietary supplement and botanical formulation projects.

Essencefield supplies 4:1, 5:1, and 10:1 dry extract ratio grades, with 10:1 serving as the primary commercial specification. Standard material is typically produced at 80 mesh, with carrier-free and carrier-supported formats and water or water–ethanol extraction systems available for different formulation and processing needs.

Ingredient Profile & Common Uses

Dipsaci Radix is obtained from the root of Dipsacus asper, a member of the Caprifoliaceae family. Dipsacus asperoides C.Y.Cheng & T.M.Ai is recognized as a botanical synonym. Unlike simply milled Xu Duan root powder, this ingredient is produced through extraction and concentration, resulting in a more concentrated botanical material suitable for commercial formulation.

The 10:1 grade represents the main concentrated format, while lower-ratio options provide alternative concentration levels for different product designs. Commercial selection may also consider particle size, carrier system, and analytical controls. Extract ratio describes the relationship between botanical raw-material input and finished dry extract and should not be interpreted as the percentage content of an individual constituent.

The powder has a characteristic botanical odor, bitter to slightly astringent taste, and natural brown color. It is primarily used in concentrated supplement systems and dry botanical blends. In water-based formulations, the material behaves as a dispersible botanical ingredient rather than a clear-soluble powder, making wetting, sedimentation, color contribution, and taste masking relevant during formulation development.

Application Areas

Capsules

The powder can be incorporated into single-botanical and multi-ingredient capsule formulations. Particle size, carrier selection, powder flow, and blend uniformity should be evaluated before high-speed filling.

Tablets

It can be used in compressed botanical tablets after evaluation of flow, compression behavior, disintegration, and compatibility with binders, fillers, lubricants, and other plant extracts.

Botanical Powder Blends

The concentrated material is suitable for multi-botanical premixes and powdered supplement systems. Matching particle size with major blend components helps reduce segregation during transport, blending, and filling.

Granules & Stick Packs

The ingredient can be incorporated into granulated powders and unit-dose stick packs where powder flow, wetting, bitterness, color, and sedimentation are addressed during formulation.

Key Constituents & Extract Profile

Dipsaci Radix contains a characteristic combination of triterpenoid saponins, iridoid glycosides, and related phenolic constituents. Asperosaponin VI, also known as akebia saponin D, is an important triterpenoid saponin associated with the root and can serve as a useful marker when chemically controlled material is required.

Published chromatographic studies have also identified constituents including loganin, loganic acid, sweroside, dipsacoside A, dipsacoside B, chlorogenic acid, and related caffeoylquinic acids. This broader constituent profile makes chromatographic fingerprinting useful for evaluating botanical identity and chemical consistency beyond a single marker compound.

Extract ratio and marker assay describe different characteristics. A 10:1 designation defines concentration by the relationship between botanical input and finished extract, while an asperosaponin VI assay measures the level of one defined constituent.

Technical & Quality Considerations

Botanical authentication is particularly important because teasel species and commercial names are not always used consistently across the supply chain. Quality evaluation should begin with authenticated root material and maintain botanical traceability through extraction. TLC can support identity screening, while HPLC marker analysis or chromatographic fingerprinting provides greater chemical discrimination for supplier qualification and batch comparison.

Physical performance is influenced by concentration, drying conditions, particle size, and carrier selection. Particle-size formats from 60 to 200 mesh can be selected for different manufacturing needs. The natural brown color and bitter, slightly astringent sensory profile can affect lightly colored or directly consumed products, while aqueous formulations should account for haze, wetting behavior, and sedimentation.

During scale-up, capsule and tablet manufacturers should evaluate powder flow, blend uniformity, compression behavior, and compatibility with other ingredients. For stick packs or dispersible powder systems, pre-blending can improve ingredient distribution, while wetting and settling tests help establish preparation characteristics. Carrier-free material and maltodextrin-, inulin-, or gum-acacia-supported formats can also provide different powder-handling and dispersion properties.
