Chl a and b are the two types widely distributed in higher plants. Overview Information Chlorophyll is a green pigment found in plants. Chlorophyll, a natural green pigment, takes part widely in the nutrition of humans.A high level of chlorophyll in especially green vegetables increases its importance in terms of biological functions and the possibility of being protective agents against several chronic diseases. Chlorophyll A is a principal pigment while chlorophyll B is accessory pigment. Its absorption maxima are around 452, 585, 625 nm and 452, 585, 627 nm in diethyl ether and acetone respectively.

Hydrology Project Training Module File: “ 40 Measurement of Chlorophyll-a.doc” Version March 2000 Page 17 Measurement of Chlorophyll • Chlorophyll a is found in all green plants • Gives an estimate of algal concentraion, 1 – 2% of dry weight of algae. [4] It has a blue-green color and is an accessory pigment, particularly significant in its absorption of light in the 447–52 nm wavelength region. Occurrence. [1][2][3], It has a blue-green color and is an accessory pigment, particularly significant in its absorption of light in the 447–52 nm wavelength region. Chlorophyll a, shown here, is called the “universal” chlorophyll because it is present in almost all photosynthetic organisms. Effects of chlorophyll and chlorophyllin on low-dose aflatoxin B(1) pharmacokinetics in human volunteers. Abstract. • Chlorophyll a is used to indicate the state of fertilisation of a water body. Its absorption maxima are around 444, 577, 626 nm and 447, 579, 629 nm in diethyl ether and acetone respectively. MgN. 6. There are several kinds of chlorophylls namely chlorophyll a,b,c,d and e; bacteriochlorophyll a,b,c,d and e and bacterioviridin. concentration of chlorophyll a, b, c was calculated in mg/L.
