Characterization of phyto-nanoparticles from Ficus krishnae for their antibacterial and anticancer activities.

BACKGROUND: Ovarian cancer is deadliest of fifth leading cause of death in women worldwide. This is due to advanced-stage disease rate associated with the development of chemoresistance. Hence, the current study emphasizes the process of synthesis of silver nanoparticles (AgNPs) from green chemistry method. Ficus krishnae is a perennial plant, native to India, used in folklore medicine to treat various diseases. OBJECTIVE: For the development of reliable, ecofriendly, less expensive process for the synthesis of AgNPs against bacterial and ovarian cancer. METHODOLOGY: The synthesis of silver nanoparticles from stem bark of Ficus krishnae was carried out. The synthesized nanoparticles are subjected by UV-Vis spectrophotometer, scanning electron microscopy (SEM), X-ray diffraction (XRD) analysis and FTIR analysis. The antibacterial efficacy also determined by disc diffusion method, MIC, CFU and growth curve. In vitro cytotoxicity effect of aqueous extract and AgFK nanoparticle in ovarian cancer cell line by MTT assay was performed. RESULTS: The formation of AgNPs was confirmed by UV-VIS spectroscopic absorbance shown that peak at 435 nm. XRD photograph has indicated the face-centered cubic structure of the synthesized AgNPs. SEM study demonstrated that the size from 160 to 260 nm with interparticle distance, whereas shape is spherical. The particle size were ranging from 15 to 28 nm determined by XRD pattern. The antibacterial and cytotoxicity activity of this nanoparticle has showed a potential activity when compared with standards. CONCLUSION: The present study confirms that the biosynthesized AgNPs from Ficus krishnae stem bark extract have a great affiance as antibacterial and anticancer agent.

A Novel Potential Reproductive Effects of Pterocarpus marsupium Methanolic Extract on Testosterone Propionate Induced Polycystic Ovary Syndrome in Female Albino Rats.

OBJECTIVE: To investigate potential reproductive effects of Pterocarpus marsupium methanolic extract on testosterone propionate induced Polycystic Ovarian Syndrome (PCOS) in female albino rats. METHODOLOGY: PCOS was induced in female albino rats by daily injecting testosterone propionate for 15 days intraperitoneally. Animals are divided into five groups with six rats per group. Group 1: Control group received olive oil, Group 2: Testosterone propionate+natural recovery, Group 3: Testosterone propionate + a dose of clomiphene citrate (standard), Group 4 and 5: Testosterone propionate + low dose (200mg/kg) and high dose (400mg/kg) b.w respectively for 15 days. Various biochemical and histopathological investigations were assessed. RESULTS: Methanol extract of Pterocarpus marsupium was able to exert its protective effect successfully by restoring all the parameters to normal and diminishing the cysts found in ovaries. CONCLUSION: Pterocarpus marsupium showed potential reproductive effects on testosterone propionate induced PCOS female albino rats and could be used as an alternative therapy in the treatment of PCOS.
