Bioactivity and Plant Growth Stimulation Studies using Mangifera indica L. Gum

Abstract

The potential of plant gum as a bioactive agent and plant growth enhancer has not been exploited well and plant gums are suitable for such purposes as they are non-toxic and biodegradable. Therefore, the aim of this study was to verify the potential of Mangifera indica (MI) gum as a bioactive agent and plant growth enhancer. Plant gum was collected from the bark of MI and polysaccharides were extracted, purified and characterized with ultraviolet-visible (UV-Vis) spectroscopic, Fourier-transform infrared spectroscopy and gas chromatography (GC) analyses. Crude and purified polysaccharides were tested for their antibacterial and antioxidant activity. The crude gum was subjected to plant growth stimulation study like germination percentage, shoot length, root length and wet weight of chilli (Capsicum frutescens). The effect of MI gum on soil porosity and water holding capacity (WHC) was also tested. UV-Vis and GC analyses of gum polysaccharide showed the presence of several types of monosaccharides in MI gum. The plant gum did not show any antibacterial activity against Escherichia coli, Pseudomonas sp., Bacillus sp. and Staphylococcus aureus, but was found to exhibit low antioxidant activity. The gum was found to enhance the seed germination and seedling growth in-vitro and in-vivo.

Evaluation of the Toxic Effect of Bauhinia purpurea Mediated Synthesized Silver Nanoparticles against In-vitro and In-vivo Models

“…An incision in the tree’s bark was created, and gum exudate was collected repeatedly. The gum was shade dried before being pulverized using a mortar and pestle and stored in an airtight container [ 20 ]. All the chemicals used in this study were of analytical grade.…”

Purification and Characterization of Gum-Derived Polysaccharides of Moringa oleifera and Azadirachta indica and Their Applications as Plant Stimulants and Bio-Pesticidal Agents

“…Previously, Mangifera indica gum has been reported to improve seed germination, vegetative growth, and seedling growth in Capsicum frutescens. It was also said to improve soil porosity and water retention capacity [3].…”

“…They are bioorganic substances that are secreted from the barks of trees in response to any stress or damage/wound caused by either biotic or abiotic sources [2]. Plant gums are complex carbohydrate polymers produced predominantly by herbaceous and woody plants belonging to the Fabaceae, Combretaceae and Sterculiaceae families [3]. Gums are mostly made up of polysaccharides, which belong to the group of complex carbohydrates [4] and are known to be hydrophilic in nature [5].…”

Modification and Bioactivities of Polysaccharide extracted from Mangifera Indica gum (Mango)

“…Samrot et al, 2021 who tested Mangifera Indica gum, in which the scavenging activity of crude polysaccharide was signi cantly lower than the control and magni ed polysaccharide. Samrot et al conducted an experiment on Azadirachta indica gum, where the scavenging activity of the extracted polysaccharide was noticeably lower than the control.…”
