Abstract
Anthocyanin
indexes, quercetin, kaempferol and myricetin may provide industry with
potential new medicines or nutraceuticals. Velvetleaf (Abutilon theophrasti
Medik) leaves from 42 plant introductions (PI) were analyzed for
anthocyanin indexes while both leaves and fruit were used for quercetin,
kaempferol and myricetin concentration analysis by reverse-phase high
performance liquid chromatography. Leaf anthocyanin indexes ranged from
6.15 to 11.25 among PI. Leaf quercetin and kaempferol concentrations
ranged from 1.50 to 4.79 mg/g and 0.43 to 2.17 mg/g, respectively. Fruit
quercetin, kaempferol and myricetin concentrations ranged from 0.061 to
0.266 mg/g, 0.054 to 0.734 mg/g, and 0 to 35.87 μg/g, respectively.
Significant differences in leaf weight were also observed. Significant
correlations were found between several traits. This information
regarding anthocyanin indexes, quercetin, kaempferol and myricetin
concentrations will be useful for velvetleaf cultivar development.
Breeders and other scientists could use this germplasm that contains
high concentrations of anthocyanins, quercetin, kaempferol and myricetin
to develop new medicines or nutraceuticals from an extremely useful
weedy species.
