The Phytochemical and Comparative Anticancer Study of Methanolic and Chloroform Extracts of Psidium guajava L. Leaves of Pakistani Origin

摘要

The chief focus of our study is to evaluate the phytochemical and anti-cancer activity of methanol (PGM) and chloroform extracts (PGC) of the leaves of Psidium guajava (guava) collected from local area of district Sialkot, Pakistan. Shade dried milled leaves was subjected to extraction (maceration) with methanol and chloroform. Quantitative and qualitative screenings by GC-MS and phytochemical techniques were performed. Then different secondary metabolites and phytochemical compounds were identified which are typically associated with the existence of therapeutic characteristics. Psidium guajava has been extensively used as herbal remedies like, anti-diarrheal, antihypertensive, antibacterial, antifungal as well as to control obesity, ulcer, diabetes. In this study, both extracts of P. guajava were evaluated for their anticancer activities against HeLa cell-lines (cancerous cells). The healthiest anticancer response in the form of cell-line suppression was perceived with 200μg/mL of both extracts, PGM showed 81% and PGC exhibited 91% while the standard drug doxorubicin presented around 76% inhibition. The comparative better result was seen with chloroform extract than methanolic abstract. In conclusion, the chloroform and methanol extracts of our nominated plant from Pakistan origin has a good source of phytochemicals that revealed an outstanding anti-cancer potential.
