Alginic Acid Analysis Service

Hydrophilic Polysaccharide Alginic Acid Enhances Antacid Property

CD BioGlyco offers an alginic acid analysis based on our Pharmaceutical and Biological Analysis Service, facilitating its application in pharmaceutical formulations for improved therapeutic outcomes. Alginic acid, also known as alginate, is a hydrophilic polysaccharide extracted from brown seaweed through alkaline extraction. It forms a viscous gel when combined with water, found in the cell walls of brown algae. Comprising L-glucuronic acid and D-mannuronic acid residues linked by 1,4-glycosidic bonds, it is not an antacid but enhances antacid formulations due to its unique mechanism. Added to antacid preparations, alginic acid reacts with saliva and sodium bicarbonate to form sodium alginate. When exposed to gastric acid, this alginate precipitates into a foaming gel, creating a pH-neutral barrier against acid reflux. This property boosts the efficacy of drugs treating gastroesophageal reflux disease (GERD). However, alginic acid products are not suitable for peptic ulcer disease (PUD) treatment.

At CD BioGlyco, our alginic acid analysis service is designed to ensure the highest quality and purity standards for alginic acid samples through a series of rigorous tests. Our comprehensive approach includes three main categories of analysis: identification tests, impurities tests, and specific tests.

  • Identification test

We use advanced spectroscopic techniques such as fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (NMR) spectroscopy. These methods allow us to identify characteristic molecular fingerprints and confirm the chemical structure of alginic acid.

  • Impurities test

We use high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) to identify and quantify potential contaminants. These methods are highly sensitive and provide precise measurements of impurities, ensuring that the alginic acid meets the required purity levels.

  • Specific test

This includes a range of custom tests such as viscosity measurements, molecular weight determination using gel permeation chromatography (GPC), and thermal analysis through differential scanning calorimetry (DSC). Additionally, we perform microbial enumeration tests, loss on drying tests, and pH assessments to ensure the sample's suitability for various applications.

Through these detailed analyses, CD BioGlyco guarantees the integrity and reliability of alginic acid samples. Moreover, we also offer other Pharmaceutical Excipient Analysis Services for clients according to their needs.

Results: The article discusses the extraction and characterization of alginic acid from Sargassum wightii seaweed. The extraction method involves soaking the seaweed in formaldehyde solution, followed by washing with distilled water and treatment with HCl and sodium carbonate. The purity of the extracted alginic acid was determined through phytochemical analysis, including tests for alkaloids, carbohydrates, flavonoids, steroids, terpenoids, saponins, tannins, and phenols. The physicochemical properties of alginic acid were evaluated, including color, odor, taste, texture, pH, and moisture content. The protein, carbohydrate, lipid, fucose, and sulfate contents were also determined. Ash content was measured by combusting the alginic acid and determining the weight of the ash. Hydrolysis of alginic acid was performed to reduce viscosity and convert the polysaccharide into monosaccharides. The article also mentions the use of FTIR analysis to qualitatively analyze the active principles of hydrolyzed alginic acid. Additionally, 13C and 1H NMR analysis is conducted to identify and confirm the proton and carbon numbers of alginic acid.
