Mass spectral studies of 6,8-disubstituted-3-(3 ',5 '-disubstituted 3 ',4 '-disubstituted phenylmethyl-, ethenyl)isocoumarins

Mass spectra of 6,8-dihydroxy-3-(3 ' ,5 ' -dihydroxyphenylmethyl-, 3 ' ,4 ' -dihydroxyphenylethenyl) isocoumarins ( 2b & 3b) and their methylether derivatives (2a & 3a) are discussed. The mass fragmentation patterns wen derived with the help of LREIMS, HREIMS. and link scan measurements.
