The occurrence of metabolic disorders, such as diabetes and obesity, continues to rise globally, necessitating the exploration of alternative and effective therapeutic options. Achyranthes aspera, a traditional medicinal plant, has gained attention due to its potential pharmacological properties and minimal adverse effects. This research article aims to evaluate the phytochemical analysis, antidiabetic, and anti-obesity activities of A. aspera. The GC-MS analysis of methanolic extract of A. aspera (Aa) visualized presence of 21 known major compounds. The phytochemical analysis of Aa revealed the presence of six known compounds, which upon analysing the spectral data identified as syringic acid (1), sinapic acid (2), caffeic acid (3), luteolin (4), apigein (5), and 6-prenyl apigenin (6). Among all tested samples, 4, 5, 6, and Aa showed superior antidiabetic activity may be due to the existence of freely existing oxygenated constituents like phenolics. The antidiabetic activity of A. aspera was demonstrated through inhibition of carbohydrate-digesting enzymes. On the other hand, 4,6 and Aa derived from A. aspera has an IC50 value of 84.57±5.44 µgmL-1 , 88.24±5.58 µgmL-1 , and 72.95±4.13 µgmL-1 , respectively, indicating a moderate inhibitory effect on porcine pancreatic lipase activity.These findings highlight its potential as a natural remedy for managing diabetes and obesity-related complications. In conclusion, utilizing A. aspera as a natural source for the development of novel therapeutic interventions offers promising prospects in addressing the management of diabetes and obesity.
