Several compounds present in fruits as Polyphenol, are able to kill or inhibit the growth of microorganisms. These properties are relevant mainly in tropical areas, as Amazonian region where infectious are highly prevalent. Therefore, this study investigated the antimicrobial activity of Jatropha curcas seed cake against microorganisms. The results showed antibacterial effect of Jatropha curcas seed cake methanolic extracts on two Gram-positive bacteria and Gram-negative bacteria. Effect of Jatropha curcas seed cake on Superoxide and nitric oxide production was also estimated in macrophage cells. This result suggests its anti-inflammatory and antibacterial potential of the herb, which could be due to the bio-active principles which are anti-inflammatory and antibacterial in nature. The present study, therefore emphasizes the use of Jatropha curcas seeds as an anti-inflammatory and antibacterial drug against macrophage cells and bacteria respectively.

Objective: The study was planned to investigate antioxidant and anticancer activities with the preliminary phytochemical analysis of methanolic extracts of Vitex negundo (V. negundo), Lantana camara (L. camara) and Bauhania variegata (B. variegata) plants leaf extracts. Methods:Phytochemical evaluation was performed for all the extracts, as per the standard methods. In vitro antioxidant activities were performed by using DPPH (2,2-Diphenyl-1-Picrylhydrazyl), ABTS (2, 2'-Azino-Bis-3-Ethylbenzothiazoline-6-Sulfonic Acid) and FRAP (Ferric reducing antioxidant power assay) method and compared with standard antioxidants. The anticancer activity of plant extract was assessed using MTT colorimetric assay. Results:The study of preliminary phytochemical proved the existence of alkaloids, flavonoids and phenolic types of phytochemicals in high amount. Methanolic extract of L. camara shows minimum IC50 value for DPPH assay (48.75±2.34 µg/ml) and FRAP assay (274.66±3.65 µg/ml). In ABTS assay B. variegata extract exhibit minimum IC50 value (60.48±3.01 µg/ml). Lower the IC50 value of extract, higher the effectiveness of the plant. Methanolic extract of all plants methanolic extracts showed anticancer activity against SH-SY-5Y cells (human neuroblastoma cell) but V. negundo was more effective against SH-SY-5Y cells with IC50 value (209 µg/ml) compared to remaining extracts. Conclusion:The current finding accomplished the in vitro activities, so that plant could be a superior source of antioxidant and anticancer drugs. But further in vivo assessment was needed before adding it into the pharma industry.

The present paper focuses on the synthesis of silver nanoparticles using with different leaf extract concentrations of Vitex negundo. The biosynthesized nanoparticles were characterized by UV-vis absorption spectrophotometry, fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy, energy dispersive X-ray, atomic force microscopy, transmission electron microscopy, photoluminescence and zeta potential techniques. The formation of silver nanoparticles was confirmed by the surface plasmon resonance absorption peak at 423 nm in UV-vis absorption spectra of the synthesized silver nanoparticles. The fourier transform infrared spectroscopy indicates flavonoids as a potential reduced agents. Field emission scanning electron microscopy shows the synthesized silver nanoparticles are in spherical shape. Energy dispersive X-ray spectroscopy shows the strong peak belongs to silver, and it confirms the formation of Ag NPs. X-ray diffraction spectra of synthesized silver nanoparticles exhibit they are in face centered cubic crystalline structure. The photoluminescence spectra of synthesized silver nanoparticles show their emission peak at 489-481 nm and the emission intensity is proportional to the different concentrations of leaf extract. The spherical shaped silver nanoparticles are observed by atomic force microscopy technique. The zeta potential value is observed at -13.5 mV, which shows the synthesized silver nanoparticles are incipient instability. The antimicrobial activity of the synthesized nanoparticles is studied using the disc diffusion method, which indicates that both Gram positive and Gram negative microorganisms have been affected by the silver nanoparticles. The observed antibacterial activity could be find important applications in medicine, biology and industry.
