Table 1 shows that the ethanol extraction
of ground, dry, turmeric produced a greater total
phenolic content than from the ethanol-water
extraction. The Folin-Ciocateu method was
reported to react not only with phenols, but also
with any reductive substance present. However,
the high content of total phenols in the extracts
might refer to the high antioxidant properties (Yang
et al., 2006). The extract condition with the highest
total phenolic content was found to be the same
as the one that had the highest curcuminoid
content.
