Anti-inflammatory and antioxidant activities of the crude ethanolic extract of the kernel root of Xylocarpus mekongenesis (Lamk.) M. Roem. (Meliaceae) was evaluated in different methods. The extract showed significant antiinflammatory activity in carrageenan-induced oedema test in rats showing 69.42 % reduction in the paw volume (P<0.01) comparable to that produced by the standard drug indomethacin (70.25 %) at 24 h when the extract was fed at the dose of 400 mg/kg body weight. The percentage inhibition of the oedema paw volume was statistically significant (p<0.05) when compared with the indomethacin treated animals at 0.5, 1, 2, 4 and 6 h. The extract exhibited $IC_{50}$ value 4.78 ${\mu}g/ml$ in DPPH free radical scavenging activity test that was found to be very significant and comparable to that of the standard antioxidants ascorbic acid and BHA (1.9372 and 4.81 ${\mu}g/ml$) respectively. In nitric oxide radical scavenging test, the $IC_{50}$ value was also found fairly significant 57.37 ${\mu}g/ml$ when compared to standard ascorbic acid (36.81 ${\mu}g/ml$). In reducing power test, the maximum absorbance of the same extract was observed as 1.923 at 100 ${\mu}g/ml$ and that of ascorbic acid and BHA were 2.8111 and 1.0314 respectively. The extract showed highest antioxidant capacity at 100 ${\mu}g/ml$ concentration expressed as equivalents of ascorbic acid (1.44). The total phenolic content of the extract was also found quite high ($342.15{\pm}0.92$ mg/g of gallic acid equivalent). Therefore, the results of this study suggest the probable anti-inflammatory and antioxidant activities of the ethanolic extract of X. mekongenesis kernel root and justify its use in traditional medicines.
