What is Carbenoxolone?

Glycyrrhetinic acid is a derivative of licorice extract, which is a widely used traditional Chinese medicine in various industries such as medicine, tobacco, and food. Its primary active component, glycyrrhizic acid, possesses similar effects to adrenocorticotropic hormones and can be utilized for detoxification, anti-inflammatory, antitussive, and anti-tumor purposes. Glycyrrhetinic acid is formed when glycyrrhizic acid, the main active ingredient of licorice, undergoes hydrolysis by gastric acid or decomposition by β-glucuronidase in the liver. By rewriting the above passage, the repetition rate can be reduced.

Carbenoxolone Application

  1. Carbenolone has anti-inflammatory, anti-ulcer, anti-allergic, anti-viral, lipid-lowering, cough-relieving, anti-asthmatic, expectorant and other effects. It can also be used to prevent and treat diseases such as viral hepatitis, hyperlipidemia, and cancer.
  2.

Carbenoxolone Preparation

Take out 140g of glycyrrhizic acid powder (glycyrrhizic acid content is about 25% HPLC), add 1120ml of 95% edible ethanol, perform extraction at 40°C for 3 hours, remove insoluble impurities by filtration, and distill the filtrate to recover ethanol, obtaining extract, and then dry the extract to 100°C in a water bath to obtain 118g of dry extract with a water content of no more than 20%; grind the dry extract and take 100g, add 300ml of 70% glacial acetic acid, and add 7ml Concentrated sulfuric acid, hydrolysis and acetylation under normal pressure, heating to 98~103°C, reaction for 2 hours. After the hydrolysis and acetylation are completed, cool to room temperature, filter the precipitated solid, wash the filter cake with 250 ml of 65% acetic acid, then 200 ml of ethanol, and finally 300 ml of water, and dry at 100°C to obtain 20.21 g of acetyl Carbenolone crude product, purity is 88.2% (HPLC).

Take 20g acetylglycyrrhizic acid, add 300ml water, add 5g sodium hydroxide to adjust the pH to 13, hydrolyze under normal pressure reflux conditions for 4 hours, lower to room temperature, acidify the pH to 5.2 with hydrochloric acid, filter, and wash the filter with pure water Cake, remove inorganic substances, dry to 100°C to obtain 17.8g of crude glycyrrhizic acid with a purity of 92.9% (HPLC), and then dissolve the crude glycyrrhizic acid with 214ml of ethanol with a volume concentration of 95%, according to the weight of the crude glycyrrhizic acid Add activated carbon to 25% (4.45g) for reflux decolorization, and then filter after reflux decolorization. After recovering ethanol from the filtrate, solid precipitation occurred, and 16.4 g of glycyrrhizic acid was obtained through filtration with a purity of 98.2% (neutralization method). For further purification, the product was recrystallized three times with 95% ethanol to obtain the carbenolone product with a purity of 98% (HPLC). The total impurity peak does not exceed 2%, and the single impurity peak does not exceed 0.7%, which fully complies with the European Pharmacopoeia standards.
