In order to compare the composition of phenolic substances,
HPLC experiments were carried out for the phenolic extracts of
CECO and HECO. The attention was focused on the comparison of
the two phenolic profiles of CECO (WK + CT + CW) and HECO
(WK + CT + CW). The chromatograms of the phenolic extracts of
CECO and HECO are given in Figs. 1 and 2, respectively. Fig. 1 shows
that there are three main compounds in the phenolic region of the
chromatogram of the phenolic extracts of CECO (WK + CT + CW)
and Fig. 2 shows that there are several compounds in the chromatogram
of the phenolic extracts of HECO (WK + CT + CW). Eight
major free phenolic compounds were identified in HECO. Most of
the unidentified signals in Fig. 2 may be due to oxidised phenolic
compounds and/or bound forms of phenolic compounds that are
incorporated into coconut oil under high temperature conditions
