Unlocking the Secrets of Tragacanth with Expert Analysis

As a professional biology company, CD BioGlyco has a diverse range of Pharmaceutical Excipient Analysis solutions, and we offer our clients a multi-modal tragacanth analysis service. Tragacanth is a combination of water-soluble polysaccharides and non-water-soluble polysaccharides, presenting a white or yellowish-white powder or translucent flakes. Due to its special biological activity, tragacanth can be widely used as a pharmaceutical excipient in a variety of pharmaceutical preparations, such as creams, gels, and suspensions.

• Identification
  • The samples to be identified are placed under a microscope after the addition of an appropriate amount of ZnCl₂ iodine solution, and round or oval starch granules are present in tragacanth, with diameters ranging from 4 to 10 μm, occasionally up to 20 μm, and mostly in single granules.
  • The sample to be identified and the tragacanth standard are unfolded using the same thin-layer chromatographic plate, and the positions of the spots on the chromatographic plate are compared. If the positions are the same, it means that the sample is tragacanth.
  • The sample to be identified is wetted with ethanol and water is added in stages to form a homogeneous mucus. Then add water and barium hydroxide solution to the mucus. If there is a white flocculent precipitate, to which a small number of drops of dilute hydrochloric acid. If the precipitate dissolves, the sample is tragacanth.
• Viscosity
  After adding potassium chloride and water to the tragacanth, it is stirred until it is completely and evenly dispersed and wetted. Next, a rotational viscometer is used to test the viscosity.
• Foreign impurities
  A solution of methanol and hydrochloric acid is heated to tragacanth. After some time, the residue is collected and washed with methanol. Afterward, it is dried at 110°C to a constant weight, leaving no more than 1.0% residue.
• Microbiological limits
  The microbiological counting method is used to test the number of aerobic bacteria contained in tragacanth. It is worth noting that the total number of aerobic bacteria should not exceed 1000 cfu per 1 g of tragacanth. In addition, the total number of molds and yeasts should not exceed 100 cfu per 1 g of tragacanth, and Escherichia coli should not be present.

Frequently Asked Questions

• What are the applications of tragacanth?
  The amount of tragacanth used is usually determined by the dosage form and the grade of the gum. In the pharmaceutical field, tragacanth is used as an emulsifier and suspending agent to facilitate the development and production of creams, gels, emulsions, etc. It is also used as a diluent in tablets. On the other hand, tragacanth can also be used in cosmetics and food. Furthermore, due to its high viscosity, tragacanth can be used as an emulsifier for polymer compounds in combination with gum arabic.
• What is the composition of tragacanth?
  Tragacanth is a natural substance consisting of a mixture of water-soluble and non-water-soluble polysaccharides. 60-70 percent of tragacanth comprises the non-water-soluble fraction. Hydrolysis of tragacanth sugar produces L-arose, L-fucose, D-xylose, D-galactose, and D-galacturonic acid. In addition, tragacanth contains small amounts of cellulose, starch, protein, and incineration residue.
