Chemistry:Purple sweet potato color
From HandWiki
Short description: Natural food coloring obtained from the sweet potato
Purple sweet potato color (PSPC) is a natural anthocyanin food coloring[1][2][3][4] obtained from the sweet potato (Ipomoea batatas). Some cultivars, like the Ayamurasaki, released in Japan in 1995, are specially developed to have a higher anthocyanin content.[5]
It is reported to have potential application as an antimutagenic,[6][7] antioxidant,[8][9][6] and anti-inflammatory.[8][10][9][6] There is evidence it is protective against injury induced by D-galactose[6][8][10][9] and has potential as a treatment for galactosemia.[11]
The following chemical components of PSPC have been identified.[12][13]
- cyanidin 3-caffeoylsophoroside-5-glucoside[12]
- peonidin 3-caffeoylsophoroside-5-glucoside[12]
- cyanidin 3-caffeoyl-p-hydroxybenzoylsophoroside-5-glucoside[12]
- peonidin 3-caffeoyl-p-hydroxybenzoyl-sophoroside-5-glucoside[12]
- peonidin-caffeoyl-feruloylsophoroside-5-glucoside[12]
- cyanidin 3-caffeoylsophoroside-5-glucoside[12]
- cyanidin 3-(6′′,6′′′-dicaffeoylsophoroside)-5-glucoside[12]
- cyanidin 3-(6′′-caffeoyl-6′′′-feruloylsophoroside)-5-glucoside[12]
- peonidin 3-O-(6-O-(E)-caffeoyl-2-O-beta-D-glucopyranosyl-beta-D-glucopyranoside)-5-O-beta-D-glucoside[13]
- cyanidin 3-O-(6-O-p-coumaroyl)-beta-D-glucopyranoside[13]
- peonidin 3-O-(2-O-(6-O-(E)-caffeoyl-beta-D-glucopyranosyl)-6-O-(E)-caffeoyl-beta-D-glucopyranoside)-5-O-beta-D-glucopyranoside[13]
- peonidin 3-O-(2-O-(6-O-(E)-feruloyl-beta-D-glucopyranosyl)-6-O-(E)-caffeoyl-beta-D-glucopyranoside)-5-O-beta-D-glucopyranoside[13]
