In silico PASS-Assisted Biological Activity Predictions of a Phytoconstituent Astilbin isolated from Thelypteroid fern Sphaerostephanos arbuscula (Willd.) HolttumBy Leon Stephan Raj, A. John De Britto, D. Vanila
Abstract: Pteridophytes are the most important land plants with enormous medicinal properties. The medicinal properties of this group of plants mainly depend upon the numerous phytoconstituents present inside the plants. In the present study, the biological activity spectra of a phytoconstituent Astilbin isolated from Thelypteroid fern Sphaerostephanos arbuscula was predicted using computer-aided program—Prediction of Activity Spectra for Substances (PASS). The PASS predicted activity of Astilbin exhibited its various probable activities (Pa). …

Green Synthesis of Silver Nanoparticles Using The Leaf Extract of Micrococca mercurialis. (L.) Benth. and Its Antibacterial ActivityBy Leon Stephan Raj, A. Antony Selvi, M. Antony Fency, P. Ramakrishnan, M. Vellakani, D. Vanila
Abstract: In the present study, fresh and powder leaf extracts of Micrococca mercurialis. (L.) Benth. were used for green synthesis of metallic silver nanoparticles (SNPs). The efficacy of SNPs was tested against some human and animal pathogens. Stable SNPs were formed after adding aqueous solution of 1 mM AgNO3 with the fresh and powder leaf extracts. Quantitative analysis of green synthesized SNP was monitored by UV-visible spectroscopy. Bacteriological tests were performed …

Enumeration of Fabaceae Vegetation in Plains of Tirunelveli District of Tamil Nadu, IndiaBy Leon Stephan Raj, D. Vanila, A Saravana Ganthi
Abstract: Maintenance, management and sustainable utilization of plant coverage have required scientific recognition. The information resulted from vegetation can be useful to solve the ecological problems such as biological conservation and natural resources management and the future of an ecosystem trends can be forecasted using such information. The study presents the survey of Fabaceae flora in the plains of Tirunelveli district during 2006–2009. About 58 species belonging to different habitats have …
