E5 - Extraction of Chlorophyll from Fresh Spinach . E6 - Investigation of the Photochemistry of Chlorophyll. The aim of this experiment is to investigate the photochemistry of chlorophyll. This experiment will be performed in two lab periods. In the first lab period you will extract chlorophyll, the green pigment in leaves, from spinach.


This energy is then used by the plant to synthesize glucose from carbon dioxide and water. Chlorophyll in the leaves of plants can be extracted and separated using chromatography. A good source of chlorophyll for an extraction is a dark green leafy vegetable like spinach. Rub a fresh spinach leaf on the bottom of a strip of filter paper.

Biology Lab Report on the extraction of Chlorophyl from Plant Leaves ... etc. Red and blue light have the greatest effect on plant growth after white light The main pigment is chlorophyll which reflects green lights l Green and yellow light are the least effective Plants can utilize light in both the red and orange end and the blue end of ...


Chlorophyll Extraction. This easy science project shows simple and efficient method of chlorophyll extraction from a plant. This is only a demonstration of working method which can be refined and used for a full scale science project. Plants contain many pigments in different proportions.


Lab #5: EXTRACTION AND SEPARATION OF PLANT PIGMENTS ... liquid-phase extraction will be used to extract pigment molecules from the partially dehydrated pulverized spinach. In the third and final step, the pigment molecules will ... chlorophyll a & b (green to blue-green), and the xanthophylls (yellow with the lowest R f


stored until the next laboratory period. Period 2: Characterization 1. Thin Layer Chromatography: Before you can carry out the thin layer chromatography (TLC) on your fractions and original extract, you must save about 3-mL of the chlorophyll and –carotene fractions for UV-visible spectra. For the TLC you must concentrate the separated fractions.


Chlorophyll-b differ from chlorophyll-a only in one functional group (i.e -CHO) bounded to the porphyrin ring, and is more soluble than chlorophyll-a in polar solvents because of its carbonyl group 18. Highest extraction of chlorophylls (Chlorophyll a and b) is noted by using DEE (except chlorophyll b in Adiantum sp.).


1 5 - Chlorophyll Analysis Lab. Objectives: To determine the chlorophyll a concentration. Introduction: Chlorophylls are the essential photosynthetic pigments present in all green plants and algae, and allow them to convert sunlight into organic compounds in the process of photosynthesis.
