Carboxymethyl modification of Cassia obtusifolia galactomannan and its evaluation as sustained release carrier

Strychnos Potatorum L. Seed Polysaccharide-Based Stimuli-Responsive Hydrogels and Their Silver Nanocomposites for the Controlled Release of Chemotherapeutics and Antimicrobial Applications

“…From the 1 H NMR spectrum, the polysaccharide β-(1 → 4)-linked d -galctopyranose and β-mannopyranosyl, mannose, and galactose units are responsible for anomeric hydrogens that appear in different regions. 21 , 22 …”

“…Mannose and galactopyranose of the polysaccharide were observed at δ H 3.40 and 2.32, respectively. From the 1 H NMR spectrum, the polysaccharide β-(1 → 4)-linked d -galctopyranose and β-mannopyranosyl, mannose, and galactose units are responsible for anomeric hydrogens that appear in different regions. , …”

“…From the 1 H NMR spectrum, the polysaccharide β-(1 → 4)-linked Dgalctopyranose and β-mannopyranosyl, mannose, and galactose units are responsible for anomeric hydrogens that appear in different regions. 21,22 The 13 C NMR spectrum (Figure S2B) of the polysaccharide showed a chemical shift value of the anomeric region at δ C 104.29 ppm associated with C-1-β-D-mannose and substituted α-D-galactose. The diagnostic peak was observed at 77.97 ppm attributed to the C-4-linkage of the mannose unit, and the resonance peak chemical shift values of β-D-mannose and galactose substituted peaks were attributed to C-5 and C-6, respectively, at δ C 71.56, 73.25, and 74.26 ppm.…”

Effective encapsulation of reuterin-producing Limosilactobacillus reuteri in alginate beads prepared with different mucilages/gums

“…Its use improved the stability of the particles and the bacterium survival, mainly by increasing the tightness of the wall material and performing prebiotic activity, which can improve the cell viability by ensuring protection under gastric phase and progressively release it under enteric juices [64] . In parallel, psyllium mucilage, was related with effective improvement of the alginate particle properties, in which integrity was improved [25] , besides it was associated with prebiotic characteristics, which can benefit probiotic bacteria, conditions that can enhances the cell survival under low pH and in the presence of bile salts [55] , Furthermore, the tamarind and cassia tora gums have been used in pharmaceutical applications, such as drug delivery and sustained release agent [ [65] , [66] ] and until now there were no literature records regarding their use to encapsulate microorganisms. In this sense, our study confirmed great potential of these gums to microorganism encapsulate purposes.…”

Transcriptome and HPLC Analysis Reveal the Regulatory Mechanisms of Aurantio-Obtusin in Space Environment-Induced Senna obtusifolia Lines

“…In addition, S. obtusifolia seeds have been regarded as culinary and medicinal dual-purpose material by the National Medical Products Administration (NMPA). A recent study reported that carboxymethyl Cassia galactomannan is suitable for sustained drug delivery [ 6 ]. Because of its multiple uses, the demand for S. obtusifolia seeds is increasing.…”
