Antioxidant, cytotoxicity, and anti-human lung cancer properties of Linum Usitatissimum seed aqueous extract in the in vitro condition: A pre-clinical trial study

IntroductionLinum usitatissimum seed or flax seed is known as a potential candidate as a remedy to treat various diseases in many traditional medicines around the world. In the current study, the antioxidant, cytotoxicity, and anti-human ling cancer properties of Linum Usitatissimum seed were investigated in the in vitro condition.Material and methodsAntioxidant activity of the plant was analyzed using radical scavenging activity and ferrous ion chelating assay. MTT assay was used to evaluation of anti lung cancer of the plant.ResultsThe plant extract scavenged DPPH as a free radical with an IC50 of 34.2±0.9 µg/mL. The plant also was rich in phenolic compounds with an amount of 294.8±2.3 mg GAE/g for total phenolic content. Cell viability of Linum Usitatissimum seed was very low against lung poorly differentiated adenocarcinoma (PC-14), lung moderately differentiated adenocarcinoma (LC-2/ad), and lung well-differentiated bronchogenic adenocarcinoma (HLC-1) cell lines without any cytotoxicity on the normal cell line. The best anti-human lung cancer properties of Linum Usitatissimum seed against the above cell lines was in the case of the PC-14 cell line. According to the above findings, the Linum Usitatissimum seed may be administrated for the treatment of several types of human lung cancer in humans.ConclusionsAccording to the results, the IC50 values of plant extract against lung poorly differentiated adenocarcinoma (PC-14), lung moderately differentiated adenocarcinoma (LC-2/ad), and lung well-differentiated bronchogenic adenocarcinoma (HLC-1) cell lines were found 392, 483, and 564 µg/mL, respectively
