Ab initio NMR studies of chemical constituents of piper sarmentosum

Ab initio NMR studies of chemical constituents of piper sarmentosum

The structures of two compounds,gamma-asarone (1-ally1-2,4,5-trimethoxybenzene) {1} and asarylaldehyde (2,4,5-trimethoxybenzaldehyde) {2) from Piper sarmentosum, locally known as 'kaduk', have been studied by HNMR, CNMR spectroscopy and quantum chemical calculations. The NMR shifts are cal...
