TL;DR: The results suggest that the reduction of metal ions and stabilization of the resultant particles in the first two solutions involved the same class of biomolecules, including flavonoids, which were present in comparable amounts in both the tea leaf broth and ethyl acetate extract, but are absent in the CH(2)Cl( 2) extract of tea leaves.

TL;DR: The superb efficiency of aqueous extract of dried leaves of mahogany in the rapid synthesis of stable monometallic Au and Ag nanoparticles and also Au/Ag bimetallic alloy nanoparticles having spectacular morphologies is demonstrated.

TL;DR: In this paper, the antioxidant activity of aqueous and ethanol extracts of Indian propolis (AEP and EEP, respectively) was measured by chemical and electrochemical assays, whereas, cyclic voltammetry was used as the electrochemical assay.

TL;DR: It is demonstrated for the first time the excellent efficiency of ethanol and water extracts of a natural, non-toxic material, Indian propolis and two of its chemical constituents, pinocembrin and galangin in the rapid synthesis of stable Ag and Au nanoparticles having wide spectrum of fascinating morphologies.

TL;DR: A detailed study was performed on the antioxidant activity of the aqueous and methanol extracts (AED and MED respectively) of the stem bark of the plant, Dalbergia sissoo Roxb.
