The scientific community is searching for biosynthetic methods for the production of metallic nanoparticles. Biogenic pathway has now become a vast developing area of research. A novel route biological synthesis of silver chloride nanoparticles (AgCI-NPs) using aqueous leaf extract of Morinda citrifolia under ambient conditions were evaluated. Synthesized nanoparticles were confirmed by UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The effects of pH on biosynthesis of AgCI-NPs were investigated using UV-vis spectroscopy. TEM images showed that the diameter of stable AgCI-NPs were approximately 12 nm. FTIR spectra provide the evidence for the presence of protein as possible biomolecules responsible for reduction and capping of nanoparticles. The synthesized AgCI-NPs were observed to have a good catalytic activity on the reduction of methylene blue (MB) dye by M. citrifolia extract which has been confirmed by decrease in absorbance maximum values of methylene blue with respect to time using UV-vis spectroscopy and was attributed to the electron relay effect. © 2014 Elsevier B.V.

Present and future health care systems are more demanding on the discovery and usage of novel drugs, which should have a potent target system with the pharmacokinetic and pharmacodynamic properties. Available drugs used currently are chemically synthesized and some of them are yet to be studied for their toxicity assessment. Bioorganic phase can be an indispensable field on isolating and identifying the metabolites from the food sources has become trend in recent days. Indian food systems are embedded with the Indian system of medicine. Indian food plants and Indian spices are highly enriched with the medicinal properties. Their applications are vital in industrial and pharmaceuticals. Hence, isolation of the novel compounds is one of the goal in bioorganic phase by various methods, it may be either traditional (decoction, maceration and solvent extraction) or by recent (ultra-sonication, microwave assisted and enzymatic extraction) methods. Identification and characterization of compounds can be done through chromatographic techniques and spectroscopic methods. This chapter deliberates with phyto-constituents from the common food plant products such as vegetables, spices and condiments. Their important phyto-compounds having pharmacological actions and how they were isolated, identified and characterized using different methods were discussed. This could help in gaining knowledge on the important compounds and their properties present in food products. © Springer International Publishing AG, part of Springer Nature 2018.

Bioorganic Phase in Natural Food: An Overview

Isolation and Characterization of Bioorganic Phase from Food Source

A new series of brominated derivatives of 2, 3-dihydroquinazolin-4(1H)-one were synthesized and their structures were confirmed using IR, NMR and mass spectra. The synthesized derivatives were screened for their in vitro anthelmintic activity. The investigations on interaction of the bioactive compound, 2i with bovine serum albumin (BSA) were evaluated. The quenching mechanism of the compound, 2i was deduced based on the results of Stern–Volmer equation. The number of binding site, prediction of binding site region and the changes in the secondary structure of protein were predicted using various spectroscopic studies.

Most of the wastes emitted from the food processing industries are not utilized for any further purpose. The economic value of the food waste is very less when compared to the collection or reuse or discard. To increase the economic value we have to design the food waste as useful product or applicable in most of the current field. Nothing is waste in this world with this concept we have investigated the phytochemical analysis of drumstick peel (Moringa oleifera). The result supports the presence of phenols, alkaloids, flavanoids, glycosides and tannins. Since various functional groups containing molecules are present in the extract; it has been further subjected to antibacterial and hemolytic activities. To analysis the antibacterial studies we have employed human pathogenic Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) bacterium. The result of antibacterial activity clearly shows that it possesses significant activity on both bacterial cultures. The hemolytic activity was performed on red blood cells (RBCs). From this result we observed that drumstick peel extract has been considered as non-toxic on RBCs. Malachite green was selected to perform photocatalytic activity. The results stated that the drumstick peel extract possessed good behaviour towards photocatalytic investigation. The malachite green was degraded upto 99.7% using drumstick peel extract.
