Background: Hematite (α-Fe2O3) has been used as an antimicrobial and disinfectant agent. Nevertheless, there are limited data about antitumor potential. This study was focused on investigating cytotoxic effects of Hematite (α-Fe2O3) from Butea monosperma flower extract on MCF -7 breast cancer cells and its mechanism of action. Materials and Methods: Thus, a green method was created for the synthesis of Hematite (α-Fe2O3) using an aqueous extract of B. monosperma flower. Synthesis of Hematite (α-Fe2O3) was described by different analytical techniques including ultraviolet-visible spectrophotometer, field-emission scanning electron microscopy, X-ray diffraction, and Fourier transforms infrared spectroscopy. Cell viability was determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Reactive oxygen species (ROS) formation was measured using probe 2{\textquoteright},7{\textquoteright}-dichlorofluorescein diacetate and intracellular calcium (Cai2+) was evaluated with probe flu3-AM. Cells were treated with different concentrations of Hematite (α-Fe2O3) (1, 3, 6, 10, 15, 25, 50, and 100 μg/mL). Results: The results showed that Hematite (α-Fe2O3) hindered cell growth in a dose-dependent manner. Hematite (α-Fe2O3) appeared to have dose-dependent cytotoxicity against MCF-7 cells through activation of the ROS generation and an increase in the intracellular Cai2+ (half-maximal inhibitory concentration 52 {\textpm} 3.14). Conclusion: In conclusion, the results of this preliminary study demonstrated that Hematite (α-Fe2O3) from B. monosperma flower extract may be a potential therapeutic potential medicament for human breast cancer treatment.

Background: Diabetes mellitus is a chronic metabolic disorder that has significant impact on the health, quality of life and life expectancy, as well as on the health care system. Butea monosperma Lam. Kuntze (Fabaceae), commonly known as palash, is widely used in the treatment of various diseases and disorders including diabetes. Materials and Methods: The present study was planned to evaluate the antidiabetic effect of aqueous extracts of B. monosperma leaves and bark in streptozotocin-induced severely diabetic rats. The animals were divided into four groups, with each consisting of six rats, viz. control, diabetic control, leaf extract-treated and bark extract-treated groups. Treatment was continued for 6 weeks. The biochemical estimations included blood glucose and serum insulin levels. Histopathology of pancreas was also performed. Results: The results indicated that both leaf and bark extracts of B. monosperma produced insignificant antihyperglycemic activity. The leaf and bark extracts reduced blood glucose to an extent of 28\% and 11\%, respectively. It was also evidenced that both leaf and bark extracts did not increase insulin synthesis or secretion and did not improve pancreatic architecture as reflected by the histopathologic studies. Conclusions: The findings of the study emphasize that B. monosperma does not possess significant antidiabetic activity in severe experimental diabetes at the dosage tested.
