After one hour, the rubbing alcohol should be green, as it now contains the chlorophyll. Operating conditions, such as the IL concentration and solid-liquid ratio, were optimized by a response surface. Dim the lights and keep the sample tubes in the freezer : Because chlorophyll degrades when exposed to light and heat, this procedure and all others associated with analyzing chlorophyll should be carried out in dim light conditions. As it comes up to a simmer the chlorophyll coagulates and rises to the surface.

Chlorophylls include chlorophyll a and chlorophyll b (Pavia et al 208). *Cellulose and other plant compounds are insoluble. This chlorophyll is easily metabolized and used to build new red blood cells and pull out carcinogenic substances from the body.

Boiling water kills the cells and destroys enzymes which can promote chlorophyll degradation. enhanced solvents for the extraction of chlorophylls from spinach leaves. If using baby spinach 1-3 leaves should be plenty .

Cut 2g of spinach leaves into small pieces with scissors and put into the mortar. Zinc complex formation increased at pH values of 7.0 or greater. Place your first leaf sample in the mortar. Extracting plant pigments For extraction we recommend 100% acetone or at least 90% isopropyl alcohol 1. In your own words, write an explanation of how pigments in the spinach extract were separated by your thin layer chromatography experiment - identify the stationary and mobile phases of the setup and how they caused the separation of the pigments. The purity and identity of the . Chlorophyll is a photoreceptor made up of two molecules: chlorophyll a, chlorophyll b. As a photoreceptor, it absorbs light energy from a source such as the sun. Under carotenoids, there are pigments called and -carotene and xanthophylls. You may need to add excess water to remove all of the spinach remnants from the blender. 2 and shows the separation of carotenoids (peak I), chlorophylls b/b' (peak II), chlorophyll a (peak III) and chlorophyll a' (peak IV). *Cold acetone because we only want to dissolve polar components including pigments. Transfer the mixture to a centrifuge tube. Here is how: 1) Wait for another 10-15 minutes for the leaf powder to settle on the bottom of the test tube.
