Phytochemical Screening of Calligonum polygonoides Stem Extract Collected from Jaisalmer District of Rajasthan, India

Abstract

This study aimed to qualitatively analyze the hydroalcoholic stem extracts of Calligonum   polygonoides to identify major secondary metabolites with potential pharmacological significance. C. polygonoides, commonly known as “Phog” a plant native to the arid regions of Rajasthan, India, thrives under extreme desert conditions characterized by high temperatures, intense solar radiation, and limited water availability. This study aimed to qualitatively analyze the hydroalcoholic stem extracts of C. polygonoides to identify major secondary metabolites with potential pharmacological significance. Plant samples were collected from Chelak Village, Jaisalmer, a region within the Thar Desert, where plants have evolved unique biochemical adaptations to survive harsh environmental stresses. The stem of C. polygonoides was collected, dried, and ground into a fine powder, followed by hydroalcoholic extraction. Standard phytochemical tests were conducted to detect key bioactive compounds. The qualitative screening confirmed the presence of flavonoids, tannins, phenolic compounds, saponins, sterols, quinones, glycosides, and alkaloids in the stem extracts. These secondary metabolites are renowned for their diverse therapeutic properties, comprising anti-oxidant, anti-inflammatory, antimicrobial, and anticancer properties. The occurrence of these bioactive compounds in C. polygonoides underscores its potential as a valuable source of plant-derived pharmaceuticals. The ability of this plant to produce a rich array of phytochemicals despite extreme desert conditions suggests its evolutionary adaptation to environmental stress, which may contribute to its medicinal properties. This study highlights the significance of exploring desert flora for novel bioactive compounds that could lead to the development of sustainable, plant-based therapeutic agents.
