“…Moreover, the presence of glucuronic acid as an end residue in the branched galactan core of CG [12,[77][78][79], imparting a net polyanionic nature to the polysaccharide [12,14], may additionally contribute to the canceling out of the neat charge with the positive charges generated by the high voltage [70], thereby diminishing the overall electric field strength experienced by the biopolymer in its flights to the collector, hence helping to suppress the whipping motion and facilitating the strong bundling of the fibers. A similar canceling-out charge effect was also reported by Urbanek et al [70] when processing chitosan/polycaprolactone fibers via The above experiments (Control_1-Control_3) suggest that the particular morphology of spontaneous natural fiber alignment into very thick fiber bundles is a unique feature of sample S12, contributed by the high content in the mixture of the comb-like branched CG polysaccharide [72,73].…”

“…Furthermore, fibers from Control_3 showed a higher degree of aggregation if compared to those of Control_2, which could be due to the presence of the plasticizing and hygroscopic glycerol [71] as a binding element for the flying fibers. The above experiments (Control_1-Control_3) suggest that the particular morphology of spontaneous natural fiber alignment into very thick fiber bundles is a unique feature of sample S12, contributed by the high content in the mixture of the comb-like branched CG polysaccharide [72,73].…”

This study investigates the unique morphology and mechanical properties of multi-jet electrospun cashew gum (CG) when combined with high-molecular-weight polyethylene oxide (PEO) and glycerol. Cashew gum (CG) is a low-cost, non-toxic heteropolysaccharide derived from Anacardium occidentale trees. Initially, the electrospinnability of aqueous solutions of cashew gum alone or in combination with PEO was evaluated. It was found that cashew gum alone was not suitable for electrospinning; thus, adding a small quantity of PEO was needed to create the necessary molecular entanglements for fiber formation. By using a single emitter with a CG:PEO ratio of 85:15, straight and smooth fibers with some defects were obtained. However, additional purification of the cashew gum solution was needed to produce more stable and defect-free straight and smooth fibers. Additionally, the inclusion of glycerol as a plasticizer was required to overcome material fragility. Interestingly, when the optimized formulation was electrospun using multiple simultaneous emitters, thicker aligned fiber bundles were achieved. Furthermore, the resulting oriented fiber mats exhibited unexpectedly high elongation at break under ambient conditions. These findings underscore the potential of this bio-polysaccharide-based formulation for non-direct water contact applications that demand elastic properties.

“…Cashew trees ( Anacardium occidentale L.) have been used in folk medicine worldwide, particularly in America and Africa (Ajileye et al, 2015 ; Costa et al, 2021 ; Cruz Reina et al, 2022 ). A number of bioactive metabolites (e.g., phenolics, flavonoids, anthocyanins, and carotenoids) and biological properties (e.g., antimicrobial, antioxidant, antidiabetic, anticancer, and anti‐inflammatory activities) were found in different parts of cashew trees (da Silva et al, 2022 ). A sesquiterpene lactone zoapatanolide A was isolated from the ethanol extract of A. occidentale cultivated in Nigeria and exhibited potent cytotoxicity against HeLa cells, with an IC 50 value of 36.2 μM (Taiwo et al, 2017 ).…”

The current study aimed to identify the chemical constituents and bioactivities of the crude ethanolic extract (CEE) and its fractions (ethyl acetate (EAF), hexane (HEF), and aqueous (AEF)) from leaves of cashew (Anacardium occidentale L.) grown in Vietnam. A total of 31 compounds which belong to alkanes, hydrocarbons, iodine, terpenoids, phenolics, and flavonoids were determined by a gas chromatography–mass spectrometry (GC–MS) analysis, with bis(2‐ethylhexyl) phthalate being the most prevailing compound. The highest total phenolic and flavonoid contents were obtained in the EAF, followed by HEF, CEE, and AQF. All samples showed promising in vitro antibacterial activity, enzyme inhibition, and anticancer activity. Among the samples tested, the EAF exhibited the highest enzyme inhibition activity against α‐amylase and α‐glucosidase (IC50 values of 51.24 μg/mL and 99.29 μg/mL, respectively), cytotoxicity activity against HeLa cells (IC50 value of 79.49 μg/mL), and antibacterial activity against Bacillus subtilis and Escherichia coli with MIC values of 5 mg/mL and 2.5 mg/mL, respectively. These findings suggest that the leaves of A. occidentale cultivated in Vietnam are a promising source of bioactive components and that EAF is a promising bioactive material warranting further pharmaceutical investigation.
