TI  - Chemical screening of olive biophenol extracts by hyphenated liquid 
      chromatography.
PG  - 176-89
AB  - Chemical screening using reversed phase HPLC-photodiode array detection 
      (RPLC-DAD) and RPLC-electrospray ionisation mass spectrometry (RPLC-ESI-MS) is 
      widely applied as an approach to streamline natural products research. The full 
      potential of this approach is demonstrated in this paper by application to the 
      chemical screening of olive products including olive mill waste (OMW). Out of 100 
      biophenols previously reported in olive products, the on-line RPLC-DAD-ESI-MS was 
      able to confirm the presence of 52 compounds in OMW. This included a number of 
      simple phenols, flavonoids and secoiridoids. By careful examination of the 
      combined DAD and ESI-MS data, extra information was elucidated including: the 
      site of glycosidation on the phenol ring of hydroxytyrosol; the identity of the 
      other luteolin-glucoside isomer as luteolin-4'-O-glucoside; identifying rutin 
      rather than the previously reported hesperidin (and the reasons for possible 
      mis-assignment); and the detection of diastereomers of 4-hydroxyphenylethyl 
      alcohol-deacetoxy elenolic acid dialdehyde (4-HPEA-DEDA) and 
      3,4-dihydroxyphenylethyl alcohol-deacetoxy elenolic acid dialdehyde 
      (3,4-DHPEA-DEDA).
