Aims: To investigate in vitro anti-inflammatory activity of aqueous, methanol, dichloromethane, and hexane extracts of Artocarpus nobilis Thw. leaves and stem bark using heat-induced protein denaturation test (egg albumin denaturation). Methodology: About 500 g of each matured, fully expanded leaves and stem bark of Artocarpus nobilis were collected, washed and air-dried. Leaves and stem bark parts were grounded to obtain a fine powder material. The extractions were obtained using the decoction extraction method. Anti-inflammatory activity was evaluated using the heat-induced egg albumin denaturation method. Diclofenac sodium was used as the positive control. Results: Results showed that Diclofenac sodium exhibited an IC50 value of 243.4 µg/mL and methanolic stem bark extract had an IC50 Value of 249.8 µg/mL) for heat-induced egg albumin protein denaturation test. R² and P values for aqueous, methanol, dichloromethane, and hexane extracts indicated that there was a strong, statistically significant correlation (P |
