In addition, peak 35 (C28H31O16) with m/z at 623.1596, was
suggested to be either isorhamnetin 3-O-rutinoside or lucenin-2-
methyl ether, noting that both compounds have been previously
reported in gourds (Abu-Reidah et al., 2012). In fact, a very lowintensity
spectrum was detected in the MS/MS spectrum analysis
for this compound, with which it was not possible to distinguish between
the two isomers.
