Cinnamates and coumarins from the leaves of Murraya paniculata

Phytochemical investigations on aerial parts of Murraya paniculata have resulted in the isolation of two new natural products, methyl 2-methoxy-5-hydroxycinnamate and 8-(2′-oxo-3′-methyl) butoxy-7-methoxycoumarin along with the two known compounds, methyl 2,5-dihydroxycinnamate and murrayatin, isolated for the first time from this plant. The structures of these compounds were determined by using spectroscopic methods including two-dimensional NMR.
