lphenol, pyrocatechol, ethyl gallate, ethyl succinate, vanillic
acid, ethyl 3,4-dihydroxybenzoate, furan-2-ol, and 4-(4-
hydroxyphenyl)butan-2(S)-ol. We expected that a few
compounds of the identified phenolic constituents may be
used as specific molecular marker compounds for quality
control and evaluation of physiological activity in the
manufacturing process of BR wine. However, there is no
available study on behavior of phenolic compounds during
BR wine manufacturing. In addition, investigation for
correlations between phenolic compounds and biological
activities during BR wine manufacturing has not yet been
performed.
In this study, we report change in the contents of total
phenolics and total anthocyanins during the manufacturing
of BR wine. In addition, phenolic compounds were
analyzed by GC-MS and HPLC to specify (a) molecular
marker compound(s) as an indicator for estimation of
quality and physiological activity of BR wine. Moreover,
antioxidant activities of BR wine and its fruits were also
evaluated by DPPH radical-scavenging assay and copper
ion-induced lipid peroxidation in rat plasma after oral
administration of BR wine
