Abstract
Background: Mentha piperita, a naturally occurring herb, is utilized in medicinal formulations. It possesses abundant bioactive elements, including flavonoids and phenolic acid compounds,that exhibit various properties such as antioxidants, anti-inflammatory and anti-cancer.
Objective: In the present study, chemical constituents of essential oil extracted from Mentha piperita were analyzed and identified through GC-MS. In vitro antiproliferative activity was performed on A549 lung cancer cell line lines. In silico study was conducted by Schrodinger’s Maestro’s software to identify chemical constituents in the plant as potential EGFR (Epidermal Growth Factor Receptors) inhibitors.
Methods: Hydro-distilled essential oil was analyzed by GC-MS to identify chemical components based on the retention index and mass fragmentation pattern, which was then tested for its antiproliferative activity by MTT assay against human lung cancer cell lines. All the identified constituents were investigated in silico for their affinity towards EGFR (Epidermal Growth Factor Receptors).
Result: A total of thirty constituents were identified where D-carvone (56.69%), L-limonene (12.36%), squalene (3.36%), cis-carveol (2.93%), and α-amorphene (2.36%) were observed as major constituents of the essential oil. The essential mentha oil also exhibited antiproliferative activity against lung cancer cell lines with an IC50 value of 86.05 µg/ml. Furthermore, from the in silico study, five constituents were identified to have a better affinity for EGFR (Epidermal Growth Factor Receptors) than that of the standard drug Osimertinib.
Conclusion: In the present study, the aerial part of the plant Mentha piperita was hydrodistilled.Thirty phytoconstituents were identified through GC-MS data. An in-silico study was performed using Schrodinger software, and a further in vitro study was performed in which essential oil showedgood antiproliferative activity against the A549 cancer cell line.
