Question

For the "ISOLATION OF CHLOROPHYLL AND CAROTENOID PIGMENTS FROM SPINACH" we have to do a purification scheme and from spinach (which contains pigments, water, sugars, waxes, cellulose, starch and salts,) after grinding with acetone, and then centrifuged, I was wondering what will be in the supernatant and precipitate.

I already know acetone, water, and pigments will be in the supernatant.

Answer 1

The solid pellet will contain the waxes, cellulose, and salt crystals.

The supernatant will contain the pigments, water, sugars,and starch.

Answer 2

THANKS SOO MUCH!! You are the best!
