Multifaceted analysis of Wrightia tinctoria: Extraction, physicochemical profiling, and phytochemical exploration

Wrightia tinctoria, also known as pala indigo plant or dyer’s oleander plant, is a valuable medicinal tree found across India and neighboring regions. This study aims to comprehensively analyze Wrightia tinctoria through Soxhlet extraction, physicochemical profiling, and phytochemical exploration. The introduction provides a background on the botanical significance of Wrightia tinctoria, its traditional medicinal uses, and its chemical composition, emphasizing its importance in various traditional healing practices across different regions. The materials and methods section outlines the selection of Wrightia tinctoria leaves, seeds and stem for the study, their collection, and the preparation of leaf powder. Soxhlet extraction using different solvents was conducted to isolate active compounds. Physicochemical analysis involved determining moisture content, ash content, pH, and solubility. Additionally, qualitative phytochemical screening was performed to identify various phytoconstituents. Results reveal the extraction yields of Wrightia tinctoria seed, leaf, and stem using ethanol as the solvent for Soxhlet extraction. Physicochemical properties, including moisture content, ash content, pH, and solubility, varied across different plant parts, highlighting their diverse chemical compositions and potential applications. The phytochemical analysis of crude and hydroalcoholic extracts demonstrates the presence and concentration of alkaloids, flavonoids, tannins, saponins, and glycosides in Wrightia tinctoria. Differences in phytochemical composition among plant parts and extraction methods underscore the plant's pharmacological diversity and therapeutic potential.
