A concise total synthesis of the plant alkaloid (±)-leuconolam (1) has been achieved. A regio- and diastereoselective Lewis-acid mediated allylative cyclization was used to establish, simultaneously, two adjacent tetrasubstituted carbon centers. Furthermore, an essential arene cross-coupling to a hindered haloalkene was enabled by the use of a novel 2-anilinostannane.

In the 21st century, plant-derived metal nanoparticles (PDMNPs) have gained considerable interest because of their tremendous and remarkable potential as therapeutic agents well development less expensive, safer, easier biomedical equipment. PDMNPs are synthesized from salts or oxides by using plant extracts plants diversified bioactive compounds that can act reducing stabilizing at time nanopa...

Development of green and efficient procedures for the synthesis of metallic nanoparticleshas emerged as a significant topic in the field of nanotechnology. In this respect, using naturalresources,especially plant extract has attracted lots of attention; plant extract is a promisingalternative to traditional and chemical techniques. The plant Mucuna pruriens L. contains highconcentration of L-do...

The green synthesis of nanoscale materials is special interest to researchers all over the world. We describe a simple, robust, inexpensive, and environmentally friendly approach gold, silver, iron nanoparticles using variety biomolecules/phytochemicals as potential reducers stabilizers. controlled with different morphologies based on use plant extracts. Green synthesized can be used catalysts,...

The hypocholesterolemic effect of plant stanols is explained by a decreased intestinal cholesterol absorption due to a competition between plant stanols and cholesterol for incorporation into mixed micelles. Earlier we had suggested that plant stanols have a so far unknown action inside the enterocytes. The recent discovery of the involvement of ATP binding cassette (ABC) transporters in choles...

The present study evaluates the biosynthesis of silver nanoparticles (SNPs) mediated by xerophytic plants, Cynanchum viminale and Cynanchum sarcomedium. The reaction between plant extracts and silver nitrate solution resulted in a yellowish brown/dark brown colored solution which suggests the formation of SNPs. Physical characteristics of synthesized SNPs were determined using...
