Recent Progress on Modified Gum Katira Polysaccharides and Their Various Potential Applications

Abstract

Gum katira polysaccharide is biocompatible and non-toxic, and has antioxidant, anti-microbial, and immunomodulatory properties. It is a natural polysaccharide and exudate derived from the stem bark of Cochlospermum reliogosum Linn. Additionally, it has many traditional medicinal uses as a sedative and for the treatment of jaundice, gonorrhea, syphilis, and stomach ailments. This article provides an overview of gum katira, including its extraction, separation, purification, and physiochemical properties and details of its characterization and pharmacognostic features. This paper takes an in-depth look at the synthetic methods used to modify gum katira, such as carboxymethylation and grafting triggered by free radicals. Furthermore, this review provides an overview of its industrial and phytopharmacological applications for drug delivery and heavy metal and dye removal, its biological activities, its use in food, and the potential use of gum katira derivatives and their industrial applications. We believe researchers will find this paper useful for developing techniques to modify gum katira polysaccharides to meet future demands.

Development of Conducting Biopolymer-Based Biosensor for Heavy-Metal Ion Detection

“…6, this shows the decomposition of the Katira-cl-AAc hydrogel, PANI and Katira-cl-AAc/PANI composite in an inert atmosphere of nitrogen. [48][49][50] The first drop in the weight have been observed from 50 °C to 175 °C, which is attributed to the loss of moisture content present in the sample. An abrupt bend in the slope has been observed from 175 °C to 380 °C, which signifies the constant decomposition of the compound.…”

“…The peak at 1423.0 cm −1 is assigned, to C-OH bend. 39,40 FTIR spectrum of Katira-cl-poly(AAc) polymer shows absorption bands at 3446 cm −1 and 2927.0 cm −1 due to OH and C-H stretching vibrations respectively. The peak at 2362.5 cm −1 shows the overtones and combinations of O-H bending and C-O stretching vibrations.…”

“…Exploiting the properties of PANI, hybrid nanocomposite-based electrode having thermal, electrical and tuneable mechanical properties can be prepared with a low production cost that can be further used for the construction of a biosensor. [28][29][30] We report the comparative study of urease activity inhibition by three heavy metal ions on a PANI incorporated katira gum hydrogel, coated onto the ITO electrode as a transducer for the construction of an electrochemical biosensor (Fig. 1).…”

Comparative Screening Study on the Adsorption of Aqueous Pb(II) Using Different Metabolically Inhibited Bacterial Cultures from Industry

“…All cultures (SS, C1, C2, Cons, PB, and KP) underwent centrifugation at 9000 rpm for 10 min at 4 • C. Afterward, they were washed with ultrapure water, subjected to another round of centrifugation, and subsequently oven-dried at 74 • C for 24 h [14]. This process effectively suppressed metabolic activity, ensuring that Pb(II) removal occurred solely via adsorption.…”

Carboxymethylated Gums and Derivatization: Strategies and Significance in Drug Delivery and Tissue Engineering

“…They require some modifications because the structure of polysaccharides affects their bioactivities and physicochemical properties. The characteristic features and functional groups of polysaccharides facilitate the selective chemical or biochemical modifications of polymeric backbone that expands their applications [ 10 , 11 , 12 ].…”
