Glycyrrhizic Acid: The Definitive Guide to Benefits, Sources & High-Purity Supply

1. What is Glycyrrhizic Acid?

Glycyrrhizic Acid (GA), also known as Glycyrrhizin, is a bioactive triterpenoid saponin and the primary sweet-tasting constituent found in the roots and rhizomes of the licorice plant (Glycyrrhiza glabra L. and related species). This amphiphilic molecule is prized for its diverse pharmacological activities, intense sweetness (approximately 50 times sweeter than sucrose), and role as a critical marker compound for licorice quality and authenticity in phytopharmaceuticals, food, and cosmetic applications.

2. Zdroj produktu, chemické vlastnosti a identifikace

• Zdroj: Primarily extracted and purified from the dried roots and stolons of Glycyrrhiza glabra (European Licorice), Glycyrrhiza uralensis (Chinese Licorice), and Glycyrrhiza inflata.

• Chemické vlastnosti:

  • Číslo CAS: 1405-86-3

  • Molekulární vzorec (MF): C₄₂H₆₂O₁₆

  • Molekulová hmotnost (MW): 822.93 g/mol

  • Číslo EINECS: 215-785-7

  • Vzhled: White or pale yellow crystalline powder.

  • Rozpustnost: Soluble in hot water and hot glacial acetic acid; slightly soluble in cold water, ethanol; practically insoluble in ether and non-polar organic solvents. Forms water-soluble salts (e.g., monoammonium glycyrrhizinate).

  • Key Functional Groups: Glucuronic acid moieties linked to the aglycone (Glycyrrhetinic Acid).

3. Identifying the Best Glycyrrhizic Acid: Key Criteria
Selecting premium Glycyrrhizic Acid requires scrutiny beyond basic purity:

• Purity & Composition: Opt for high-purity standards (>98% HPLC). The best suppliers provide detailed chromatograms confirming minimal impurities like related saponins (e.g., Liquiritin) or glycyrrhetinic acid. Certificates of Analysis (COA) are non-negotiable.

• Účinnost a dodržování předpisů: Efficacy is intrinsically linked to purity and bioactivity. Ensure compliance with relevant pharmacopoeial standards (USP, EP, CP), food additive regulations (JECFA, FCC), and target market requirements (e.g., FDA GRAS status for specific uses, REACH).

• Origin & Traceability: Look for transparent sourcing of raw licorice, preferably cultivated sustainably. Origin impacts glycyrrhizin content and impurity profile. Full traceability from root to final product is a mark of quality.

• Usage Methods: Highly versatile. Used as:

  • Sweetener: In foods, beverages, confectionery (especially where a lingering sweetness is desired).

  • Flavor Modifier & Enhancer: Masks bitterness in pharmaceuticals and functional foods.

  • Functional Ingredient: In dietary supplements (liver health, respiratory support, adrenal function), traditional herbal preparations, cosmetics (skin brightening, anti-inflammatory, anti-acne), oral care products.

  • Pharmaceutical Intermediate: For the synthesis of stronger anti-inflammatory agents or hepatoprotectants.

• Cílová skupina: Food & Beverage manufacturers, nutraceutical/supplement brands, cosmetic & personal care formulators, pharmaceutical companies, research institutions.

• Zdravotní přínosy a mechanismus:

  • Anti-inflammatory & Immunomodulatory: Inhibits phospholipase A2 and prostaglandin synthesis; modulates cytokine production (e.g., TNF-α, IL-6); enhances interferon production. Useful in managing allergies, dermatitis (eczema, psoriasis topically), and potentially autoimmune conditions.

  • Antiviral: Shown activity against various viruses (SARS-CoV, HSV-1, HIV, influenza) by interfering with viral entry, replication, and cell-to-cell spread. Particularly studied for upper respiratory infections.

  • Hepatoprotective: Protects liver cells from toxins (e.g., CCl4, aflatoxin B1), reduces inflammation in hepatic tissues, may support regeneration. Used in treating chronic hepatitis.

  • Adrenal Support: Mimics aldosterone, potentially supporting cortisol metabolism and adrenal function (use with caution – see side effects).

  • Antioxidant: Scavenges free radicals and enhances endogenous antioxidant systems (SOD, GSH).

  • Expectorant & Mucoprotective: Promotes bronchial secretion and protects gastric mucosa.

• Dosage & Safety:

  • Typické dávkování: Varies greatly by application. As a sweetener/flavor: GRAS levels. For therapeutic effects (e.g., liver support, antiviral): Often 50-200 mg/day of pure Glycyrrhizic Acid. Crucially, dosage must be based on pure GA content, not crude licorice root powder.

  • Safe Intake: JECFA established an ADI (Acceptable Daily Intake) of 0-0.1 mg/kg body weight for Glycyrrhizic Acid (equivalent to ~6 mg GA for a 60kg adult). EFSA and others advise limiting continuous high intake.

  • Side Effects & Contraindications: Primarily linked to excessive intake (>100 mg GA/day for weeks/months) causing pseudoaldosteronism: hypertension, hypokalemia, sodium/water retention, edema. Contraindicated in hypertension, hypokalemia, renal/liver failure, pregnancy, and with certain medications (diuretics, digoxin, corticosteroids). Monitor potassium levels during prolonged use.

• Kritické úvahy: Source purity, documented GA content, clear usage guidelines, and stringent safety warnings regarding hypertension risk are hallmarks of a responsible supplier.

10. Deep Dive: Health Mechanisms, Innovation & Research

• Mechanismus účinku: GA exerts effects via multiple pathways: direct membrane interactions, modulation of enzyme activity (11β-HSD2 inhibition key to pseudoaldosteronism), interaction with signaling molecules (NF-κB, MAPK pathways), antioxidant gene upregulation (Nrf2 pathway), and direct binding to viral components or host receptors. Its hydrolysis to glycyrrhetinic acid (by gut bacteria) yields a more potent anti-inflammatory metabolite.

• Industrial Applications & Zhonghong’s Innovation: Beyond standard extracts, Zhonghong focuses on enhancing bioavailability (e.g., phospholipid complexes, nanoemulsions), developing highly soluble salts (Ammonium Glycyrrhizinate), and creating synergistic blends for targeted health benefits. Our patented purification technologies enable unique GA derivatives and ultra-high purity grades (>99.5%) for demanding pharmaceutical applications.

• Výzkumné hranice a výzvy: Active areas include:

  • Exploring GA’s potentiation of chemotherapeutic agents and mitigation of side effects.

  • Developing novel derivatives with improved therapeutic index (reduced mineralocorticoid effects).

  • Investigating its role in metabolic syndrome, neurodegenerative diseases, and as an adjuvant in immunotherapy.

  • Challenge: Balancing potent bioactivity with the well-documented risk of hypertension/pseudoaldosteronism remains the primary hurdle for broader therapeutic application. Precise dosing formulations and targeted delivery systems are key research goals.

11. Často kladené otázky (FAQ)

• Q: Is Glycyrrhizic Acid safe?

  • A: Yes, when used appropriately at recommended dosages. Long-term, high-dose intake (>100mg pure GA/day) can cause serious side effects (hypertension, low potassium). Consult a healthcare provider, especially if you have hypertension, heart, kidney, or liver disease, or are pregnant/lactating.

• Q: How is Glycyrrhizic Acid different from Licorice Root Extract?

  • A: Glycyrrhizic Acid is the specific purified active compound. Licorice Root Extract is a complex mixture containing GA (typically 10-25%), along with flavonoids, polysaccharides, and other compounds. Effects and dosing differ significantly.

• Q: Can diabetics use Glycyrrhizic Acid?

  • A: GA itself does not significantly raise blood glucose and is used as a sweetener in some diabetic products. However, the potential hypertensive effect is a concern for diabetics, who often have higher cardiovascular risk. Consult a doctor.

• Otázka: Jaká je trvanlivost?

  • A: Properly stored in original, unopened packaging below 25°C in a dry place, our high-purity Glycyrrhizic Acid has a shelf life of 24 months.

• Q: Where can I buy high-purity Glycyrrhizic Acid?
