“…In 2014, Ahmed et al also supported the observation that β-sitosterol- d -glucopyranoside produced nanoparticles with more-negative ζ potential (−15.9 mV), compared to the parent material (aqueous extract of D. bipinnata-mediated nanoparticles) (−12.5 mV), which suggested higher stability of pure phytoconstituent-mediated nanoparticles …”

In recent years, the progress of efficient green chemistry approaches for the fabrication of commercially viable noble metallic nanoparticles has become a major focus of researchers. The present review has focused on the various plant-mediated nanoparticle fabrication approaches, with brief discussions on the categories of various plant-mediated synthesis approaches and mechanistic aspects of plant-mediated nanoparticle synthesis. The review also focused on the commercial applications of plant-mediated noble metal nanoparticles. Significant remarks on the limitations of plant-mediated fabrication approaches with prospective future direction are also examined.

Critical Analysis on Characterization, Systemic Effect, and Therapeutic Potential of Beta-Sitosterol: A Plant-Derived Orphan Phytosterol

et al. 2016

View full text Add to dashboard Cite

Beta-sitosterol (BS) is a phytosterol, widely distributed throughout the plant kingdom and known to be involved in the stabilization of cell membranes. To compile the sources, physical and chemical properties, spectral and chromatographic analytical methods, synthesis, systemic effects, pharmacokinetics, therapeutic potentials, toxicity, drug delivery and finally, to suggest future research with BS, classical as well as on-line literature were studied. Classical literature includes classical books on ethnomedicine and phytochemistry, and the electronic search included Pubmed, SciFinder, Scopus, the Web of Science, Google Scholar, and others. BS could be obtained from different plants, but the total biosynthetic pathway, as well as its exact physiological and structural function in plants, have not been fully understood. Different pharmacological effects have been studied, but most of the mechanisms of action have not been studied in detail. Clinical trials with BS have shown beneficial effects in different diseases, but long-term study results are not available. These have contributed to its current status as an “orphan phytosterol”. Therefore, extensive research regarding its effect at cellular and molecular level in humans as well as addressing the claims made by commercial manufacturers such as the cholesterol lowering ability, immunological activity etc. are highly recommended.

Abstract. Bismuth nanoparticles were obtained via sequential photoinitiated synthesis and phase-transfer separation. Specifically, BiBr 3 was used as a starting material in propylene carbonate (PC) as the polar phase, which was topped by heptane (Hep) as the non-polar phase containing oleylamine (OA) as the phase-transfer agent. In a photoreactor set-up, this two-phase system was thoroughly mixed and illuminated by broad-band UV light emitted by a high-pressure Xe lamp.
