The MeOH extract of R. racemosus showed the greatest potential
for LPO inhibition (84%), followed respectively by those of R. idaeus
cv. Golden and R. idaeus cv. Heritage, which showed 70 and 60%
activity. R. jamaicensis and R. rosifolius inhibited lipid peroxidation
by 48 and 42%, respectively. We analyzed anthocyanins 3 and 4 at
10 mM for LPO inhibitory activity. They demonstrated 60 and 56%
activity, respectively.
