Introduction: Urtica dioica, commonly referred to as stinging nettle, is a perennial herb belonging to the family Urticaceae and is widely distributed across both temperate and tropical regions. It is traditionally recognized for its medicinal properties and has long been used in managing arthritis, rheumatism, anemia, skin diseases, and urinary tract disorders. The plant contains diverse phytoconstituents, including flavonoids, phenolic acids, alkaloids, sterols, saponins, and Triterpenoids, which contribute to its pharmacological effects such as anti-inflammatory, anti-arthritic, antioxidant, analgesic, antimicrobial, and anticancer activities. Considering its traditional applications and growing scientific interest, the present study aimed to qualitatively and quantitatively evaluate the phytochemical composition of Urtica dioica to establish its therapeutic potential.
Materials and Methods: Leaves of Urtica dioica were collected from the Garhwal region (Dehradun) of Uttarakhand and authenticated at the Botanical Survey of India, Dehradun. After defatting the dried and powdered Urtica dioica with petroleum ether, the sample was transferred to a soxhlet thimble, where extraction was performed using a hydro-alcoholic solvent system. The extracts were assessed for yield, subjected to qualitative phytochemical screening, and evaluated quantitatively for total phenolic content (TPC) using the Folin-Ciocalteu method and total flavonoid content (TFC) using the aluminium chloride assay.
Result and Discussion: The percentage yield of petroleum ether extract was found to be 0.10%, while the hydro alcoholic extract showed a significantly higher yield of 6.00%. Qualitative phytochemical analysis of the hydro alcoholic extract confirmed the presence of sterols, triterpenoids, flavonoids, alkaloids, tannins, phenols, saponins, glycosides, proteins, and amino acids, indicating a rich phytochemical profile. Quantitative evaluation revealed that the hydro alcoholic extract contained a total phenolic content of 33.56 mg GAE/g and a total flavonoid content of 29.30 mg RE/g, indicating significant antioxidant potential. These findings support the traditional and medicinal uses of Urtica dioica and suggest that its polyphenolic compounds significantly contribute to its therapeutic activities, particularly anti-inflammatory and anti-arthritic effects.
Conclusion: The present study validates the Urtica dioica as a phytochemical rich plant. Its pharmacological potential in managing inflammation, arthritis, microbial infections, and oxidative stress-related disorders. The high content of phenolic and flavonoids supports its traditional use and demonstrates its value as a source of natural bioactive compounds. With further scientific validation and clinical studies, Urtica dioica could be developed into novel therapeutic agents or herbal formulations, aligning with the vision of promoting indigenous medicinal plants for health benefits and commercialization under the "Vocal for Local" initiative.
