โฆ Synopsis
Three prenylated flavonoids and a hydroxy fatty acid were isolated from the leaves of the seedless variety of Artocarpus communis, but only one from the leaves of the seeded variety. Two of these compounds are known to show great promise as pharmaceutical and agricultural chemicals, The 'H and 13C NMR spectra were completely assigned by using a combination of 2D NMR experiments which included 'H-'H COSY, HETCOR and FLOCK sequences.
