Petroleum ether, acetone, ethyl acetate, aqueous extract, methanol and ethanol fractionate of Eichhornia crassipes (Mart.) Solms was tested for their larvicidal efficacy against the different instars (I, II, III and IV) and pupae of Culex quinquefasciatus Say. The larval mortality was observed after 24 h of the treatment. The extracts showed a(More)
Green synthesis of silver nanoparticles was carried out using the aqueous extract of Alternanthera sessilis under various experimental conditions. The aqueous extract of Alternanthera sessilis showed significant potential for the quick reduction of silver ions. The synthesized silver nanoparticles were characterized with UV-visible absorption(More)
Department of Chemistry, Avinashilingam Deemed University for Women, Coimbatore641 043 ABSTRACT Lipophilicity which plays an important role in research into the structure-activity relationship of drug action has been theoretically predicted for few chromen-2-ones and chromen-2-thiones using commercial software HyperChem 7.0 and an internet computational(More)
Eichhornia crassipes (Mart.) Solms (Waterhyacinth), an aquatic perennial herb present throughout the world, has a myriad of metabolites. Phenalenone compounds and sterols have been isolated from this plant. Extracts, as well as pure compounds isolated from this plant, have been demonstrated to possess pharmacological activities. An account of the(More)
Glutathione, a ubiquitous thiol-containing tripeptide is a low-molecular weight, water soluble antioxidant. It plays a major role in the removal of reactive species. Eichhornia crassipes is an aquatic weed possessing pharmacological potential and is a source of many antioxidants. HPLC established glutathione detection in E. crassipes was carried out with a(More)
The aqueous extract of Amaranthus dubius was used for the green synthesis of silver nanoparticles from silver nitrate solution under various conditions. The silver nanoparticles were characterized by spectrophotometric, physical and theoretical methods. The size of silver nanoparticles ranged from 10-70nm. The present approach of biosynthesis of silver(More)
Eichhornia crassipes (Mart.) Solms possess many antioxidants like glutathione, ascorbic acid etc. Two skin creams of the ethyl acetate extract of E.crassipes were evaluated for its antiageing efficacy by DNA damage inhibition assay and DPPH radical scavenging assay. The DNA damage inhibition and DPPH radical scavenging ability offered by the skin creams(More)
A facile synthesis of gold nanoparticles (GNPs) using the aqueous extracts of the aerial roots of Rhaphidophora aurea (Linden ex Andre) intertwined over Lawsonia inermis and Areca catechu was carried out under different conditions, namely room temperature, higher temperature, sonication, solar irradiation and pH variation. The surface plasmon resonance(More)
Waterhyacinth is one of the fastest growing plants which disrupt the ecological balance. The plant inspite of its obnoxious nature, is a source of various pharmacologically active compounds. Sterols were isolated from the ethyl acetate extract of waterhyacinth and characterized to be a mixture of stigmasterol and β-sitosterol based on UV, IR, 1D and 2D NMR(More)
The proximate composition and chemical constituents of the aerial roots of Rhaphidophora aurea (Linden ex Andre) intertwined over Lawsonia inermis (MM) and Areca catechu (MB) were evaluated using standard methods. The results of proximate composition of MM and MB showed the following; total ash (10-13%), acid soluble ash (32-34%), water soluble ash(More)
