mixture of co-eluted di- 4-hydroxyphenylacetic acid inositols that
could not be resolved under the LC–SPE–NMR chromatographic
conditions used. The 1H NMR spectra of isolates from fractions
4 and 8 showed broad similarities that, along with HPLC–
QTOF-MS/MS data, suggested a range of derivatives were present
in both of these fractions.
