Sporopollenin is the main structural constituent present in the outer wall (exine)
ofspores and pollen in vascular plants.
This biomacromolecule has been intrigued researchers due to it's highly resistant
nature which witnessed by the presence of spores and pollen in sedimentary rocks
and coals. The structure and biosynthesis of this biomacromolecule are still
largelyunknown.
Consideration of the previous facts our aim in this research is to synthesis of
synthetic analogous of sporopollenin with various chain length aliphatic
ethers/esters substituted aryl ester compounds of p-hydroxy benzoic acid
derivatives and compare with the natural sporopollenin samples.
Comparison with Lycopodium (un treated) sporopollenin and Cedrus (treated)
sporopollenin , IR spectroscopic data of our analogues were shown much similar
carboxylic acid & ester peeks to the above natural sporopollenin.
We are not yet able to tell all analogous may identical to sporopollenin,but we
conclude, It has some similarity to natural compound, need to be further analysis
of these analogues.
