A chalcone (Pongamol) and phytoconstituents of Tephrosia purpurea

Abstract

Tephrosia purpurea stem extract fractions shows more amount of Cyclohexane, 1ethenyl-1-methyl-2,4-bis(1-methylethenyl)-, (1α,2β,4β)-(62.32 %). Secondary metabolites contents were higher in stem than root of T. purpurea. It is the first time a chalcone (Pongamol) was crystallized from the column chromatography fraction of T. purpurea stem extract identified by using FT-IR and XRD. Quantitative analysis of T. purpurea stem and root reveals that total saponins, tannins and phenols (mg/g plant powder) contents were higher in the former than the latter part of the plant respectively.

Mycogenical Synthesising AgNPs Using Two Native Egyptian Endophytic Fungi Isolated from Poisonous Plants

“…Also, bacterial permeability and respiration are disrupted (Kvítek et al, 2005). Interaction with phosphorus-containing compounds prevents protein synthesis and DNA replication (Morones et al, 2005), also by deactivating biological enzymes, and increases reactive oxygen species production (Sahayaraj et al, 2012). Furthermore, the accumulation of AgNPs in the cell nucleus, cytoplasmic membrane, and cytoplasm induced a shrinkage of the treated cells size as well as cytoplasmic content leakage, which confirmed the results of this investigation (Abdel-Hafez et al, 2016;Sarkar et al, 2011b).…”
