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).
Results: 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 showed good
anti proliferative activity against the A549 cancer cell line.
