Phytochemical Screening of Coriandrum sativum Extract and Influence in Chemical Properties of Sunflower Oil

Abstract

Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. An antioxidant is a molecule that inhibits the oxidation of other molecules. This study was designed to determine the effect of coriander extract on the chemical properties of fresh and storage sunflower oil. Coriander oil was extracted by water steam distillation process, then GC-MS was used to determine the chemical profile of coriander oil which revealed that the coriander seeds oil contains 24 compounds were; Heptanal, α-Thujene, α-Pinene, Camphene, β-Phellandrene, β-Pinane, p-Cymene, γ-Terpinene, 1-Octanol, Linalool, Camphor, Trimethy-cyclohexene carboxaldehyde, Decanal, Cuminaldehyde, cis-2-Decenal, Thymol, 1-Propanol, 2-Methyl-1-phenyl, trans-2-Dodecenal, Tetradecanoic acid, Phthalic acid, Dibutyl phthalate, Tetradecanoic acid, Diisobutyl phthalate and Palmitic acid. The chemical properties (peroxide, acid and saponification value) of sunflower oil were examined for both fresh and storage sample. The storage sample was tested during five interval period along 75 day. The coriander oil was appeared significant clear effect (p ˂ 0.05) on chemical properties of sunflower oil, so the study revealed that the coriander oil had clear influence on the chemical properties of the sunflower oil and mainly on the reused edible oil sample. The study could be attributed that to the coriander extract is richly oil in antioxidants such as monoterpens and sesquiterpenes which serves to decline the high autoxidation of sunflower oil.
