Resumen en inglés From the stem bark of Pongamia pinnata, two new compounds, 3-methoxy-(3²,4²-dihydro- 3²-hydroxy-4²-acetoxy)-2²,2²-dimethylpyrano-(7,8:5 ²,6²)-flavone and 3-methoxy-(3²,4²-dihydro-4²- hydroxy-3²-acetoxy)-2²,2²-dimethylpyrano-(7,8:5 ²,6²)-flavone, were isolated, along with six known compounds, caryophyllene oxide, obovatachalcone, 8-hydroxy-6-methoxy-3-pentyl-1H-isochromen-1-one, 6,7,2,2-dimethylchromono-8,g,g-dimethylallylflavanon e, isolonchocarpin, ovaliflavanone A. Their structures were determined on the basis of the spectroscopic data interpretation
