“…The physiochemical properties of gums are determined by the chemical nature and the molecule shapes. All gums have one common similarity, which is the ability to thicken water and aqueous systems, though the rheological properties of the systems might vary depending on the types of gums being used [24]. Gums have gained many applications in various fields.…”

With the continuing efforts to explore alternatives to petrochemical-based polymers and the escalating demand to minimize environmental impact, bio-based polymers have gained a massive amount of attention over the last few decades. The potential uses of these bio-based polymers are varied, from household goods to high end and advanced applications. To some extent, they can solve the depletion and sustainability issues of conventional polymers. As such, this article reviews the trends and developments of bio-based polymers for the preparation of polymer electrolytes that are intended for use in electrochemical device applications. A range of bio-based polymers are presented by focusing on the source, the general method of preparation, and the properties of the polymer electrolyte system, specifically with reference to the ionic conductivity. Some major applications of bio-based polymer electrolytes are discussed. This review examines the past studies and future prospects of these materials in the polymer electrolyte field.

“…Many plants produce exudate gums or mucilages; gums are usually produced in response to wounding or some other abiotic stress, such as disease, while mucilages are produced as part of the normal metabolism of the plant [9]. These water-soluble, non-starch polysaccharides are used commercially for their ability to alter the physicochemical properties of aqueous solutions and have a wide range of food and non-food applications [10]. Currently, gum arabic is the most widely used exudate gum, and other exudate gums, such as tragacanth, karaya, and ghatti, which were previously important, are used in only small amounts today [10,11].…”

Polysaccharide mucilages, including those from okra ( Abelmoschus esculentus ), and other members of the family Malvaceae, and from seeds, such as chia ( Salvia hispanica ), basil ( Ocimum basilicum ) and Plantago species, are not produced commercially, but are being actively researched [9,10].…”

Water-soluble, non-starch polysaccharides from plants are used commercially in a wide range of food and non-food applications. The increasing range of applications for natural polysaccharides means that there is growing demand for plant-derived polysaccharides with different functionalities. The geographical isolation of New Zealand and its unique flora presents opportunities to discover new polysaccharides with novel properties for a range of applications. This review brings together data published since the year 2000 on the composition and structure of exudate gums, mucilages, and storage polysaccharides extracted from New Zealand endemic land plants. The structures and properties of these polysaccharides are compared with the structures of similar polysaccharides from other plants. The current commercial use of these polysaccharides is reviewed and their potential for further exploitation discussed.

“…The term ‘gum’ as applied to water-soluble substances refers to natural non-starch polysaccharides and their structurally modified derivatives. Mucilages is a term that was used to describe the slimy aqueous dispersions produced by plants, animals and microbes, which consist basically of water-soluble polysaccharides including starches and modified starches [ 63 ]. Gums and mucilages are used in many pharmaceutical applications such as emulsifyers, suspending agents, binders and disintegrants as well as sustaining agents in tablets and as gelling agents [ 64 ].…”

Polymeric Plant-derived Excipients in Drug Delivery

Drug dosage forms contain many components in addition to the active pharmaceutical ingredient(s) to assist in the manufacturing process as well as to optimise drug delivery. Due to advances in drug delivery technology, excipients are currently included in novel dosage forms to fulfil specific functions and in some cases they directly or indirectly influence the extent and/or rate of drug release and absorption. Since plant polysaccharides comply with many requirements expected of pharmaceutical excipients such as non-toxicity, stability, availability and renewability they are extensively investigated for use in the development of solid oral dosage forms. Furthermore, polysaccharides with varying physicochemical properties can be extracted from plants at relatively low cost and can be chemically modified to suit specific needs. As an example, many polysaccharide-rich plant materials are successfully used as matrix formers in modified release dosage forms. Some natural polysaccharides have even shown environmental-responsive gelation characteristics with the potential to control drug release according to specific therapeutic needs. This review discusses some of the most important plant-derived polymeric compounds that are used or investigated as excipients in drug delivery systems.
