Physicochemical Standardization of Mucilage Obtained from Althaea officinalis Linn – Root

Background: The genus <em>Cissus</em> (Vitaceae) is known for its medicinal properties. <em>Cissus quadrangularis</em> is a well-known medicinal plant, but other species are less explored. Objective: To evaluate the antioxidant and anti-inflammatory activities of <em>Cissus arnottiana</em>. Materials and Methods: The methanolic extract of <em>C. arnottiana</em> leaves was evaluated for antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide, and hydroxyl radical scavenging assays. Anti-inflammatory activity was assessed using the carrageenan-induced rat paw edema model. Results: The extract showed significant antioxidant activity in a dose-dependent manner. In the anti-inflammatory assay, the extract at 200 and 400 mg/kg doses significantly reduced paw edema compared to the control group. Conclusion: <em>C. arnottiana</em> possesses significant antioxidant and anti-inflammatory properties, supporting its traditional use.
