Brassica juncea has many important phytochemical compounds like phenols, tannins, saponin, flavonoids, alkaloids, carbohydrates, proteins and important non-polar metabolites that possessed biological and nutrient importance.
The study employed extraction of fatty non polar components with petroleum ether from B. juncea (mustered) seeds and applying chemical analysis of mustard seeds extract with HPLC technique to investigate the chemical composition of the oil seeds that the plant rich with. Besides; study the effect of B. juncea non-polar seeds extract on the growth of Leishmania tropica promastigotes in vitro.
Results showed that the mustard seeds were rich with important fatty acid such as Erucic acid, -Oleic acid and Palmatic acid as matched the retention times of the standard used in the study. These compounds had been found to be toxic for cutaneous leishmaniasis culture that, affected the parasites with prolonged treatment periods.
