The phenolic pattern of bergamot juice was the first objective
attained in this work. The main peaks identified by HPLC by coinjections
with pure standard were narirutin (r.t. 18.8 min), naringin
(r.t. 19.8 min), isorhoifolin (r.t. 21.6 min) and rhoifolin (r.t.
22.6 min); rutin (r.t. 20.4 min), on the other hand, was present in
lower amounts. LC/MS/MS analysis confirmed the presence of
these metabolites and allowed the identification of additional compounds:
neoeriocitrin, neoponcirin, hesperidin and neodiosmin.
The spectrometric parameters are briefly summarized in Table 2.
