Whereas the flavonoid profile
from green asparagus commercial varieties is characterized by
containing rutin (quercetin-3-O-rutinoside) as main flavonoid
and representing about 90% of total flavonoid content, in triguero
asparagus as much as eight different flavonoid glycosides derived
from three distinct aglycones (quercetin, kaempferol and isorhamnetin) have been identified, being the percent of rutin 50% of total
flavonoid content (Fuentes-Alventosa et al., 2008). This greater
variety of flavonoids found in triguero asparagus could be related
to its major antioxidant and antifungal activities, among others.
