Astragaloside A Powder — High-Purity Astragaloside IV & Cycloastragenol Alternative
Astragalus membranaceus (Fisch.) Bunge — dried root
GINKVORA Astragaloside Ⅳ powder (≥98% HPLC) is a bioactive cycloartane-type triterpenoid saponin extracted from the dried root of Astragalus membranaceus — a plant with over two millennia of use in traditional Chinese medicine.
Astragaloside A — The Telomerase-Activating Saponin for Longevity & Renal Health
Astragaloside A (CAS 84687-42-3; INCI: Astragaloside A) is a bioactive cycloartane-type triterpenoid saponin extracted from the dried root of Astragalus membranaceus (Fisch.) Bunge — a plant that has anchored traditional Chinese and Ayurvedic pharmacopoeia for over two millennia. Structurally related to the more widely known Astragaloside IV, Astragaloside A shares the same triterpenoid backbone and key pharmacological properties, including telomerase activation, renal protection, immunomodulation, and anti-inflammatory activity.
Unlike synthetic alternatives, Astragaloside A is extracted through a solvent-based isolation and multi-step purification process, yielding a consistent ≥98% purity profile that meets both research-grade and commercial formulation standards.

Astragaloside A vs. Cycloastragenol vs. Astragaloside IV — Full Comparison
| Property | Astragaloside A | Astragaloside IV | Cycloastragenol |
|---|---|---|---|
| Type | Cycloartane saponin (glycosylated) | Cycloartane saponin (glycosylated) | Aglycone (deglycosylated) |
| Source | A. membranaceus root extract | A. membranaceus root extract | Hydrolysis product of Astragaloside IV |
| Telomerase Activation | ✓ Yes (hTERT upregulation) | ✓ Yes | ✓ Yes (potent, direct) |
| Purity Grade Available | ≥98% HPLC | ≥98% HPLC | ≥98% HPLC |
| Kidney Protection | ✓ Strong evidence (TGF-β1/Smad) | ✓ Strong evidence | Limited data |
| Immunomodulation | ✓ Yes (broad: T-cell, macrophage, cytokine) | ✓ Yes | Moderate |
| Anti-Inflammatory | ✓ Yes (NF-κB, TNF-α, IL-6 suppression) | ✓ Yes | ✓ Yes |
| Bioavailability | Good (glycosylated form) | Good (glycosylated form) | Marginally higher (no sugar groups) |
| Cost Efficiency | High (greater extraction yield) | Moderate | Low (additional hydrolysis step required) |
| Best For | Supplement capsules, functional beverages, kidney health, longevity stacks | Same applications; interchangeable | Premium anti-aging where bioavailability justifies cost premium |
For formulators: Astragaloside A delivers the same telomerase-activating and renal-protective benefits as Astragaloside IV, at a higher cost efficiency due to greater extraction yield from the raw plant material. For most dietary supplement and functional food applications, Astragaloside A is the practical, results-equivalent choice. Cycloastragenol — while having slightly higher bioavailability — carries a significant cost premium and lacks the renal protection data that distinguishes the glycosylated saponins.
4 Core Benefits of Astragaloside A — Mechanisms & Evidence
1. Telomerase Activation for Cellular Longevity
Astragaloside A has been shown to upregulate telomerase reverse transcriptase (hTERT) expression, extending telomere length and delaying cellular senescence in multiple in vitro models. This mechanism positions it as a leading anti-aging ingredient for longevity-focused supplement brands and functional cosmetic formulations targeting the growing "longevity skincare" category.
2. Kidney & Renal Protection
Research demonstrates significant protective effects against diabetic nephropathy and IgA nephropathy through attenuation of TGF-β1/Smad signaling and reduction of podocyte apoptosis. This renal-directed benefit is unique among anti-aging saponins and opens a differentiated product positioning angle for kidney health supplements — a high-demand, underserved market segment.
3. Broad-Spectrum Immunomodulation
Through regulation of T-cell proliferation, macrophage polarization, and cytokine balance (IL-2, IFN-γ, IL-10), Astragaloside A modulates both innate and adaptive immune responses. This immunomodulatory profile supports its use in immune-boosting supplement stacks, seasonal wellness formulas, and post-recovery nutrition products.
4. Anti-Inflammatory & Antioxidant Defense
In multiple studies, Astragaloside A has suppressed NF-κB signaling pathways and reduced pro-inflammatory markers including TNF-α, IL-6, and COX-2. It also enhances endogenous antioxidant enzyme activity (SOD, GSH-Px), making it valuable for joint health, systemic inflammation management, and skin anti-aging formulations.
Formulation Guide
Recommended Addition Method
- Dietary supplement capsules: Direct encapsulation at 10–100 mg per serving. Compatible with vegetarian (HPMC) and gelatin capsule formats. Pairs synergistically with NMN, resveratrol, quercetin, and CoQ10 for comprehensive longevity stacks.
- Functional beverages / powdered drink mixes: Due to limited aqueous solubility, pre-dispersion in a small amount of food-grade ethanol is recommended before blending into water-based formulations. Alternatively, microencapsulation can improve dispersibility.
- Topical / skincare formulations: Incorporate into serums, creams, and facial oils at 0.1%–0.5% for anti-inflammatory and collagen-preserving benefits.
Recommended Use Levels
| Application Type | Typical Dosage / Concentration |
|---|---|
| Dietary supplement capsules | 10–100 mg per serving (daily) |
| Functional beverage / drink mix | 10–100 mg per serving |
| Anti-aging serum / cream | 0.1%–0.5% (topical) |
