Acidified methanol extract of pithecellobium dulce fruit pericarp
resulted significantly higher values than the methanol extracts. The
Figure 1 shows total anthocyanin content in acidified methanol was
found to be 32mg/g and 29mg/g in methanol extracts respectively.
Several authors reported that acidified methanol preserves the
extracted anthocyanin in their original form better than the other
solvent system. Adinarayana et al, 1985 and Zasochnaja et al, 1980
reported the anthocyanin like Quericitin, kaempferol in the leaves of
Pithecellobium dulce.
