The difference in TPC and TFC in Sataw- Dan and
Sataw- Khao may be due to the different degrees of phenolic
polymerisation, solubility of phenolics and interaction of
phenolics with other constituents (Silva et al., 2007). According
to the hydrophobic structure of their molecules,
flavonoids extraction may require a longer extraction time
than phenolics extraction to obtain the highest yield.
