with the major peaks matching the
various flavonols. The major flavonols with a known
structure are labelled. A non-flavonoid compound was also
present, and was identified as rosmarinic acid, after
comparison with published data (Bloor et al., 1998;
Troncoso et al., 2005). Rosmarinic acid was excluded from
the calculations of other flavonoid total concentration
(Table 1) as it is not derived from the flavonoid biosynthetic
pathway.
