Dong Quai Extract Powder

Dong Quai Extract Powder is a concentrated botanical ingredient produced from the root of Angelica sinensis (Oliv.) Diels, an Apiaceae species commonly known as Dong Quai, Dang Gui, Chinese Angelica, or Tang Kuei. Unlike ground root powder, the extract concentrates soluble botanical constituents associated with the characteristic phthalide, phenylpropanoid, and polysaccharide profile of A. sinensis root.

Commercial sourcing centers on two main specification formats: 1% ligustilide standardized extract tested by HPLC and 10:1 root extract defined by botanical extraction ratio. The standardized grade provides a defined chemical marker for analytical control, while the ratio grade describes botanical concentration without implying a specific active-compound assay.

Ingredient Profile & Common Uses

Dong Quai extract is produced from Angelica sinensis root and is commercially distinct from whole Dong Quai root powder as well as extracts of related species such as Angelica acutiloba and Angelica gigas. Botanical identity matters because these species differ in phytochemical composition. Characteristic constituents of A. sinensis include phthalides such as ligustilide and butylidenephthalides together with phenolic compounds including ferulic acid.

Commercial grade selection generally follows either marker standardization or botanical extraction ratio. A 1% ligustilide HPLC grade is appropriate when formulators and quality teams need a defined quantitative marker. A 10:1 ratio extract instead expresses the relationship between starting botanical material and finished extract. These specifications therefore represent different procurement criteria rather than interchangeable descriptions of concentration.

The extract is used primarily in botanical dietary supplements, traditional herbal formulas, functional nutrition products, and selected personal-care formulations. Its mixed phytochemical composition influences formulation behavior: phthalides include relatively lipophilic and volatile constituents, while phenolic acids and polysaccharide fractions have different polarity and dispersion characteristics. These differences are particularly relevant when moving from dry dosage forms into aqueous or semi-solid systems.

Application Areas

Botanical Dietary Supplements

Used in capsules, tablets, powder blends, and multi-botanical products requiring a concentrated Angelica sinensis root ingredient. Marker-standardized material supports formulations where a defined chemical assay is part of raw-material qualification.

Traditional Botanical Formulas

Suitable for Dang Gui–based botanical combinations where authentic root identity and a consistent extract profile are important for supplier qualification, formulation development, and repeat sourcing.

Functional Nutrition Formulations

Can be evaluated for nutrition powders and selected functional-food systems. Development work should consider botanical flavor, wetting, dispersion, haze, and sedimentation rather than assuming complete aqueous solubility.

Personal-Care Formulations

Used in selected cosmetic and personal-care development projects where botanical extract composition, color, odor, solvent compatibility, and stability influence finished-formulation performance.

Marker Compounds & Extract Profile

Phthalides are an important part of the chemical identity of Angelica sinensis root. Characteristic compounds include Z- and E-ligustilide, butylidenephthalides, senkyunolides, ferulic acid, coniferyl ferulate, and polysaccharide fractions. Their relative distribution contributes to the analytical and physical profile of the resulting botanical extract.

For standardized material, HPLC provides quantitative control of the designated marker, while chromatographic profiling can provide broader information about characteristic phthalides and related constituents. Marker assay should therefore be interpreted as one analytical attribute within the wider extract profile rather than as a direct measure of total botanical concentration.

Pharmacopeial evaluation of Dong Quai root also recognizes butylidenephthalides and phenylpropanoids as relevant chemical groups. These reference constituents support botanical and chemical identity evaluation, but the complete extract remains a multi-component botanical ingredient and should not be assigned the CAS number, molecular formula, or molecular weight of an individual phytochemical.

Technical & Quality Considerations

Quality evaluation begins with authenticated Angelica sinensis root identity and analytical controls appropriate to the purchased grade. Quantitative assay provides control for marker-standardized material, while chromatographic profiling helps assess characteristic phthalide patterns and differentiate the ingredient from related Angelica species. This combination is more informative than relying on a botanical name or extraction ratio alone.

Physical behavior depends on the extract profile, extraction system, and any carrier used in the commercial material. Phthalide-rich fractions contain relatively lipophilic constituents, while other fractions are more polar. Dong Quai extract therefore should not automatically be treated as universally water soluble. Aqueous formulation development should evaluate wetting, dispersion, haze, sediment formation, and compatibility with the finished-product matrix.

The phthalide-rich fraction also requires attention during processing and storage because characteristic constituents can be sensitive to light, heat, and oxidative exposure. Dry supplement development should evaluate blend uniformity, powder handling, compression, capsule filling, and sensory contribution. Liquid and semi-solid systems require additional assessment of dispersion, precipitation, flavor, color, and chemical-profile stability throughout manufacturing and storage.
