Glycyrrhizic Acid Powder

What Is Glycyrrhizic Acid?

Glycyrrhizic acid powder is derived from the roots and rhizomes of licorice, a leguminous plant, and is the main active ingredient in licorice, with a content of about 10%. Glycyrrhizic acid, also known as glycyrrhizin and glycyrrhizin, is a glycoside composed of glycyrrhetinic acid and 2 molecules of glucuronic acid. White to light yellow crystalline powder, odorless, with a specific sweetness, the sweetness is about 200 times that of sucrose. Its sweetness is different from sweeteners such as sucrose. It takes a while to have a sweet taste after the entrance, but it lasts for a long time. A small amount of liquiritin and sucrose can use 20% less sucrose without changing the sweetness. Although it has no fragrance, it has fragrance-enhancing effect. The aqueous solution is weakly acidic, and the pH value of 2% solution is 2.5~3.5. Insoluble in water, dilute ethanol. Soluble in hot water, it becomes viscous jelly after cooling. Glycyrrhizic acid is a triterpene saponin. In addition, there are liquiritin, isoliquiritin and so on. Glycyrrhiza sp., a leguminous plant, is an important traditional Chinese medicine. It is used in 74 of the 110 prescriptions in "Treatise on Febrile Diseases". It is extracted from licorice and has a special sweet taste. It is mainly used in food, and it is also used in other industries such as medicine, cosmetics and cigarettes. Because glycyrrhizic acid is often accompanied by pseudoaldosteronism in clinical application, experts have carried out a large number of chemical synthesis and structural modification of it, and glycyrrhizic acid derivatives have a wide range of clinical applications.

What Are The Benefits?

Anti-Inflammatory
Glycyrrhizic acid powder has a clear anti-inflammatory mechanism, which can inhibit the metabolic level of phospholipase A2/arachidonic acid (PLA2/AA), NF-κB and MAPK/AP-1 key inflammatory response signals induced by inflammatory stimuli in the initial stage , inhibit the activity of inflammatory response signals related to the three inflammatory pathways, down-regulate the upstream related pro-inflammatory cytokines of inflammatory pathways, including TNF-α, IL-8, IL-1β, IIL-6, related chemokines and cyclooxygenase (COX) expression, blocking downstream inflammatory pathways, including nitric oxide (NO), prostaglandin (PG) and reactive oxygen species (ROS) generation.
Anti-Oxidation
It can induce the production of Ⅱ enzymes and antioxidant enzymes. The former mainly detoxifies and excretes carcinogens and toxins. The latter maintains the balance of free radicals/oxidants and antioxidants in the intracellular environment.
Antiviral
There are six steps in the replication process of most viruses, namely adsorption, invasion, uncoating, biosynthesis, assembly and release. Among them, adsorption is the key to determine the success of infection and also the core of its specificity. Adsorption of viruses to cells requires that the adsorption proteins on the virus surface specifically match the cell surface receptors. This is like the docking of a spacecraft and a space station, requiring precise matching. Previous literature has revealed that the novel coronavirus 2019-nCoV achieves specific adsorption through the interaction between its spike protein and human ACE2 protein.

Glycyrrhizic acid can not only inhibit virus replication, but also inhibit virus adsorption and membrane penetration in the early stage of virus replication, and at the same time interfere with virus DNA and RNA replication, thereby inhibiting virus proliferation and protecting cells from virus damage role.
Liver Protection
Studies have found that glycyrrhizic acid also exhibits good hepatoprotective activity in some hepatitis animal models. In lipopolysaccharide (LPS) and D-galactosamine (GalN)-induced liver injury, glycyrrhizic acid was able to completely inhibit IL18-induced ALT increase. Glycyrrhizin can alleviate liver microcirculation-induced liver injury (histology, liver enzymes) and reduce hepatocyte apoptosis by reducing microcirculation changes and preventing endothelin interaction. Its hepatoprotective effect.

Anti-Ulcer Effect: Glycyrrhizic acid has a protective effect on digestive tract ulcers. It can increase the mucus secretion of the gastric wall mucosa, form a protective barrier, and reduce the damage of gastric acid to the gastric wall. In addition, glycyrrhizic acid can also inhibit the growth of Helicobacter pylori and improve ulcer symptoms caused by gastric bacterial infection. Therefore, glycyrrhizic acid is often used to treat digestive system diseases such as gastric ulcer and duodenal ulcer.

Anti-Allergic Effect: Glycyrrhizic acid has anti-allergic effect. It inhibits the release of histamine, reducing tissue swelling and itching caused by allergic reactions. In addition, glycyrrhizic acid can also regulate the balance of the immune system and reduce the severity of allergic reactions. Therefore, glycyrrhizic acid is often used in traditional Chinese medicine to relieve allergic rhinitis, urticaria and other allergic diseases.

Lowering Blood Pressure: Glycyrrhizic acid has a certain effect on lowering blood pressure. It blocks the synthesis and release of adrenaline (a substance that raises blood pressure), regulates blood vessel tone, and lowers blood pressure levels. Therefore, glycyrrhizic acid is often used in traditional Chinese medicine to treat hypertension and cardiovascular disease.

What Are The Application Directions?

The application ratio of glycyrrhizic acid in various industries is as follows: 26% for pharmaceuticals and cosmetics, 70% for food, 4% for cigarettes and others.
In Terms Of Food:
1. Soy sauce: In addition to improving the salty taste to enhance the inherent taste of soy sauce, glycyrrhizic acid can also eliminate the bitter taste of saccharin and have a synergistic effect on chemical flavoring agents.
2. Pickles: In the brine method of pickling pickles with saccharin, the bitterness of saccharin can be eliminated. In the process of pickling, it can overcome the shortcomings of fermentation failure, discoloration and hardening caused by adding less sugar.
3. Seasoning: This product can be added with pickling seasoning liquid, seasoning powder or temporary seasoning when eating, which can increase the sweetness and reduce the strange smell of other chemical seasonings.
4. Bean paste: Pickled herring with small sauce can increase the sweetness and make the taste even.

In Terms Of Pharmaceutical Cosmetics:
1. Glycyrrhizic acid is a natural surfactant, and its aqueous solution has weak foaming property.
2. It has AGTH-like biological activity and has strong antibacterial and anti-inflammatory functions. It is often used to treat mucosal diseases, and it can prevent dental caries and mouth ulcers when used in oral hygiene products.
3. It has a wide range of compatibility, and its use in skin care products can enhance the efficacy of other active substances in sun protection, whitening, antipruritic, conditioning, and scar healing.
4. Composite with aescin, aescin, etc., used as a high-efficiency antiperspirant.
