CF-1: the three-fold ethanol precipitate from the hot water extracts. CF-2: the isoelectric precipitate from the 2%-NaOH extracts. CF-3: the three-fold ethanol precipitate from the 2%-NaOH extracts post isoelectric precipitation. CF-4: the three-fold ethanol precipitate from the 10%-KOH extracts post isoelectric precipitation.
