Pharmaceutical excipients not only maintain the stability, safety, or homogeneity of the preparation, but also promote drug dissolution, control drug release speed and release location, or serve as carriers to directionally transport drugs. With the development of pharmaceutical technology, pharmaceutical excipients have gradually attracted the attention of pharmaceutical researchers and have shown unique advantages in specific fields. CD BioGlyco assists clients in researching carbohydrate-related Pharmaceutical Excipients and provides analytical services such as physical property inspection, content determination, chemical identification, and determination of related substances. Our one-stop solution for Pharmaceutical and Biological Analysis also helps you analyze the performance of Pharmaceuticals and Biologicals.
Dextrate is a carbohydrate mixture obtained by enzymatic hydrolysis and purification of starch. It is available in anhydrous and hydrated forms and is used as pharmaceutical excipients or sweeteners. We provide worry-free dextrate property inspection, content determination, chemical performance testing, and other services.
After receiving samples from clients, we check their appearance, color, and shape, and test their solubility in water, ethanol, propylene glycol, and dilute acid.
After checking the appearance and solubility, we test the glucose content of the sample. We use the glucose standard as a control and use the titration method to test the glucose content in the sample. Take the alkaline copper tartrate test solution and heat it to boiling. Then titrate it with the sample to be tested, rotate and shake continuously, add methylene blue solution near the endpoint, slowly titrate with the sample to be tested until the blue color disappears, and calculate the glucose content in the sample.
We refer to standard methods to help clients evaluate the pH, weight loss on drying, ignition residue, and heavy metals of samples.
Technology: Dextran excipients and human cell model
Journal: Processes
IF: 3.5
Published: 2022
Results: The authors used a specially designed human cell model to evaluate the effects of different concentrations of cellobiose, lactose, sucrose, trehalose, isoleucine, glycine, methionine, dextran, mannitol, and (2-hydroxypropyl)-β-cyclodextrin lyophilized formulation excipients on cell viability. The results showed that dextran was the only excipient that was well tolerated at concentrations up to 100 mg/mL, demonstrating high biocompatibility.
