Background:
Tribulus terrestris
, a plant known for its pharmacological properties, was investigated in this study for its potential anticancer effects against oral cancer cells. The study aimed to explore the phytochemical composition of
T. terrestris
seed extract and evaluate its cytotoxic, pro-apoptotic, antioxidant, anti-inflammatory, and antimicrobial activities.
Materials and methods: Methanolic seed extracts of
T. terrestris
were obtained and subjected to phytochemical analysis to identify bioactive compounds. The cytotoxic effect of the extract on oral cancer cells was evaluated using the MTT (3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) assay, while pro-apoptotic effects were assessed through dual fluorescent staining. Antioxidant activity was measured using hydrogen peroxide and erythrocyte aggregation assays, while anti-inflammatory activity was evaluated through inhibition of albumin denaturation.
Results: Phytochemical analysis revealed the presence of alkaloids, tannins, saponins, flavonoids, and phenols in
T. terrestris
seed extract. The extract demonstrated concentration-dependent cytotoxicity against oral cancer cells, with 100 μg/mL showing significant growth inhibition. Pro-apoptotic effects were observed, with characteristic morphological changes in cancer cells treated with the extract. Antioxidant activity was demonstrated by the extract, with methanol fraction of a flower (MFF) exhibiting the highest capacity, followed by total trichome fraction (TTF), and a positive correlation between phenolic content and free radical scavenging effectiveness was noted. Antimicrobial activity against various pathogens, including bacteria and fungi, was also observed, with higher concentrations showing increased efficacy.
Conclusion: The study concludes that methanolic extracts of
T. terrestris
possess significant anticancer, antioxidant, anti-inflammatory, and antimicrobial activities. These findings highlight the potential of
T. terrestris
as a candidate for further research and clinical applications, either alone or in combination with other agents, for the treatment of oral cancer and associated conditions.
