1. Astragalus Extract Powder for Supplements

Astragalus Extract for Bulk Botanical Ingredient Sourcing

Astragalus extract is a botanical ingredient derived primarily from the roots of Astragalus membranaceus, a plant traditionally used in Chinese herbal practices. Available in extract powders and marker-standardized grades, it is used in dietary supplements, herbal formulations, and functional Wellness Products, with specifications selected according to active constituents, formulation requirements, and quality-control objectives.

Product Overview

Astragalus root extract is valued for its characteristic botanical constituents, including astragalosides, polysaccharides, and flavonoids. The composition of a finished extract depends on the botanical material, extraction process, concentration method, and standardization target.

For B2B buyers, the key purchasing consideration is the distinction between a general root extract, a polysaccharide-standardized extract, and an astragaloside-standardized extract. These materials are not interchangeable on a specification-for-specification basis. Selecting the correct type helps align ingredient identity, analytical testing, formulation performance, and finished-product labeling.

What Is Astragalus Extract?

Astragalus extract is produced by processing the roots of Astragalus membranaceus, commonly known as Huang Qi or milkvetch root. The botanical material is extracted using an appropriate solvent system, followed by concentration and drying to produce a powder suitable for further formulation.

Polysaccharides and astragalosides are two important constituent groups used to characterize commercial Astragalus extracts. Astragaloside IV is a specific saponin frequently referenced in analytical studies and standardized ingredient specifications. Total astragalosides and astragaloside IV are different measurement targets and should not be treated as equivalent.

Buyer Guide: Choosing the Right Astragalus Extract Specification

The most important purchasing decision is which constituent or extraction characteristic defines the material. A generic extract ratio, a polysaccharide assay, total astragalosides, and astragaloside IV describe different properties. Buyers should specify the measurement target before comparing quotations or calculating ingredient equivalence.

Frequently Asked Questions

What is the difference between Astragalus extract ratio and standardized content?

An extract ratio describes the relationship between the starting botanical material and the resulting extract under a defined manufacturing convention. Standardized content measures a specified constituent or constituent group using an analytical method. An extract ratio alone does not establish the percentage of astragalosides or polysaccharides.

Is astragaloside IV the same as total astragalosides?

No. Astragaloside IV is an individual constituent, whereas total astragalosides refers to a broader measurement defined by the selected analytical method and calculation. Buyers should confirm the exact marker, method, reference standard, and reporting basis before accepting a COA or comparing products.

Which test method is used for Astragalus extract?

HPLC or UPLC is commonly used to quantify specified astragaloside markers, including astragaloside IV. Polysaccharide content requires an appropriate validated assay, which may use a colorimetric approach. The test method should be agreed in the product specification because methods and reporting conventions can affect comparability.

What is the typical shelf life of Astragalus extract powder?

A 24-month shelf life is a common reference for properly packaged dry botanical extracts stored under recommended conditions. Actual shelf life depends on the product's moisture, packaging integrity, storage environment, and supporting stability information. Buyers should follow the applicable label and batch documentation for the supplied material.

What documents should be requested when purchasing Astragalus extract in bulk?

Request a batch-specific COA, a technical data sheet, and a safety data sheet. The COA should identify the assay target, analytical method, test results, and relevant contaminant limits. Depending on the application and market, buyers may also require botanical identity information, residual solvent data, third-party test reports, and applicable certification documents.
