“…The four most intense ions from the full scan, within the mass range of m/z 400 -2000, underwent fragmentation both in collision-induced dissociation (CID) mode and higher-energy C-trap dissociation (HCD) mode. This approach enhances the capability to analyze complex sample matrices, achieving separations 5 -10 times more rapidly than conventional methods (22,23). Utilizing the LC/HRMS instrument represents an advanced method with heightened sensitivity and efficiency.…”

Background: Cancer remains the leading cause of death globally, with breast cancer being the foremost cause among women and lung cancer ranking second for both women and men. Objectives: This study aimed to identify the metabolomic content of Coleus amboinicus leaves and evaluate their anticancer activities against breast and lung cancer cells, thereby providing insights into potential alternative treatments for these cancers and initiating research on active isolates from C. amboinicus leaves. Methods: The research methodology involved maceration using ethanol, followed by multistage partitioning with solvents n-hexane, chloroform, and ethyl acetate. Phytochemical screening was performed using standard reagents to detect the presence of alkaloids, phenolics, polyphenols, flavonoids, steroids/triterpenoids, and saponins. Metabolomic profiling was conducted using LC/HRMS, and the anticancer activities against lung cancer cells (A549) and breast cancer cells (MCF-7) were assessed using the MTT assay. Results: The results showed that the C. amboinicus extract contains various secondary metabolite groups such as alkaloids, phenolics and polyphenols, flavonoids, steroids, triterpenoids, and saponins. Conclusions: The diverse metabolomic profile of the C. amboinicus leaf extract demonstrated potential activity against cancer, as evidenced by in vitro tests on lung (A549) and breast (MCF-7) cancer cells. C. amboinicus leaf extract shows promise as an active ingredient in the prevention and alternative natural treatment of lung and breast cancer. Further research and testing, both in vivo and clinically, are warranted.
