Abstract:
Chlorophyll is the green colouring matter found in many plants formed in the chloroplast
of their cells usually under the influence of sunlight and is necessary for the process of
photosynthesis. Amongst the main types of chlorophyll exist in natural plants; chlorophyll
a and chlorophyll b are very important. Chlorophyll and chlorophyll derivatives are used
in the industry as a stable, non-toxic, physiologically harmless colorant of foods,
cosmetics and medicines. Chlorophyll with 0.1% or less metal can be used as gasoline
additive and has a definite antiknock effect. Chlorophyll accelerates the vulcanization of
rubber [1]. Furthermore the anti-mutagenic and anti-carcinogenic activities of chlorophyll
have been proved and hence some studies are being carried out to use it in medicines [2].
