Questions
Question (1)
After optimal extraction, the sample was filtered
through Whatman No.1 paper, and then dried by
rotary evaporator at 40° under vacuum conditions.
The concentrated sample was loaded onto a C18
open chromatographic column of silica. Elution was
performed using three solutions with specific properties
geared to optimal anthocyanin purification. The sample
was initially eluted with 0.01 % HCl-acidified distilled
water to eliminate organic acid and sugar, followed
by ethyl acetate to remove phenolic compounds and
finally by acidified ethanol (1 % w/v citric acid, pH
2.9). The purified anthocyanin fractions were collected
for further analysis.
How many resin that I have to prepare?
How to load the resin? Just pour it into the column?
Is it have to be activated first?
Actually, I don't have any experience about this purification. This is my first time.
