Phyto-Extract-Mediated Synthesis of Silver Nanoparticles (AgNPs) and Their Biological Activities.

Background: Nanotechnology finds broad applications in the field of nanomedicine, an emerging new field used for diagnosis, treatment, prevention of diseases, and improvement of health.

Objectives: To synthesize silver nanoparticles (AgNPs) from and and to carry out their antimicrobial, insecticidal, and phytotoxic activities, a step toward the new range of nanomedicines.

Methods: Silver nanoparticles were synthesized from and by chemical reduction method, and further biological activities of these nanoparticles were compared with crude methanolic extract, prepared through cold maceration process, at the concentration of 50 mg/ml.

Integrated Omics Analyses Identify Key Pathways Involved in Petiole Rigidity Formation in Sacred Lotus.

Sacred lotus ( Gaertn.) is a relic aquatic plant with two types of leaves, which have distinct rigidity of petioles. Here we assess the difference from anatomic structure to the expression of genes and proteins in two petioles types, and identify key pathways involved in petiole rigidity formation in sacred lotus.

Short Communication: Pharmacognostic and Pharmacological evaluation of Ruellia tuberosa L.

Ruellia tuberosa Linn. of family Acanthaceae was studied to investigate the microscopical, vein islet and vein termination numbers, palisade ratio, stomatal index and different chemical parameters. The antibacterial, antifungal and phytotoxic activities of the crude extract of the plant were also determined.

Proximate and elemental analysis of five selected medicinal plants of family Solanaceae.

The proximate analysis revealed the presence of ash, moisture, protein, fiber, fats and carbohydrate. ANOVA showed that ash and moisture contents was non significant between the plant parts and phenological stages. Crude protein was non significant between the plant parts and phenological stages except for Datura innoxia parts but not for its phenolgical stages, while crude fats were non significant between the plant parts and phenological stages except for Solanum nigrum and Solanum surattense parts but not for their phenolgical stages.
