Effect of soils on formation of active compounds on Brassica napus L. which grow in Iraq

Abstract

In this study, phenolic compounds : Hydroquinone, Resorcinol, Salicylic acid, Vanillin and Gallic acid. were separated from crude of Herbs belonging to Brassica napus that were collected from four sites, three of which are located within the city of Mosul are : Al-Rashidiya (area used for the cultivation of crops) and Shalalat Al-Mosul (Mosul Niagara, tourist area) and the campus of the Mosul University, while the fourth site is located in the rural of Mosul, at the village of Abukudoor, about 35 kilometers west of the Mosul city.

Separating process of compounds was Carried out through high-performance liquid chromatography  technique , the samples examined by LC-20 AD ShimadZu HPLC, which included C18(240×4.60mm) column chromatography.

Environmentally,  results showed that the soils were varying in the values ​​of the elements that have been studied, and that most of the highest values ​​of the elements observed in Al-Rashidiya site. With the exception of phosphorus, which recorded its highest value at the Shalalat Al-Mosul, and pH  Which had the highest value at the campus of the Mosul University .

In spite of the significant variation in the values ​​of the environmental factors that have been studied,  Hydroquinone have been observed in each crude extracts that have been studied, In contrast Gallic acid was absence from all of these extracts with the exception of sample that collected from Shalalat Al-Mosul.Which characterized with highest value for phosphorus (PO₄: 0.623 mg/L) compared to other sites.
