Cymbopogon citratus Stapf, popularly known as lemongrass, is an Indian species. It possibly arrived in Brazil during colonial times, where it was used as an ornamental plant, and is found growing throughout the country. There are several popular uses for this plant, including as treatment for stomach pains, diarrhea and cellulite. This plant grows in polluted and unpolluted environments such as roadsides, which can lead to changes in its chemical aspects, and consequently changes in its manufacturing products. This study examined whether there were changes in the chemical composition of plants grown in the presence or absence of environmental stress (urban pollution). The following compounds were studied, using thin layer chromatography: saponins, iridoids and proanthocyanidins, mono- and sesquiterpenes, triterpenes and steroids, flavonoids, polyphenols and alkaloids. It was concluded that this factor may have contributed to changes in the chemical composition of its leaves, reducing the synthesis of more polar compounds and promoting synthesis of possible leucoanthocyanidins for possible protection. This can lead to changes in the pharmacological and toxicological properties of tea.
