Item Antioxidant and antimicrobial activity of ethanol and water extracts of Cymbopogon jwarancusa (Jones.) leaves.(2011-11) Prasad, Chandan; Kumar, Vimal; Kamthan, K P; Singh, Udai Bhan; Srivastava, Sudhir K; Srivastava, R BThe Cymbopogon jwarancusa (Jones.) leaves extracts were explored for their antioxidant and antimicrobial activity. The ethanol extract showed highest antioxidant activity in DPPH (31.99 ± 0.50 % inhibition) and FRAP (38.79 ± 0.54 Fe (II) micromole per litre) assay while water extract showed highest antioxidant activity in βCL (54.76 ± 1.37 %) at 1mg/10ml concentration. BHT and ascorbic acid were used as standards. During antimicrobial assay, the ethanol extract found was very effective against Fusarium oxyporium f.sp-lini (85.31 ± 0.25 mm) and Staphylococcus aureus (94.37 ± 0.28 mm) at 500 ppm while water extract was found less effective against Aspergillus flavus (03.72 ± 0.19 mm) at 100 ppm concentration. The ethanol extract can be used for the applications such as food preservation as a remedy and against dental diseases.Item Chronic illness among rural population.(1988-03-01) Garg, S K; Mishra, V N; Bhatnagar, M; Singh, R B; Srivastava, R B; Garg, AItem A complete study of the vibrational spectrum of acetylglycine and its relation to the spectrum of acetylcholine.(1975-09-01) Srivastava, R B; Agarwala, S C; Roberts, N P; Gupta, V DItem Dispersion curves of poly-L-hydroxyproline chain.(1974-03-01) Srivastava, R B; Gupta, V DItem Fertility and mortality profile of an urban and rural population.(1988-04-01) Bhatnagar, M; Garg, S K; Mishra, V N; Singh, R B; Srivastava, R B; Garg, AItem Oroxylum indicum– a medicinal plant of North East India: An overview of its nutritional, remedial, and prophylactic properties.(2013-05) Deka, D C; Kumar, Vimal; Prasad, Chandan; Kumar, Kamal; Gogoi, B J; Singh, Lokendra; Srivastava, R BOroxylum indicum (family: Bignoniaceae) or Broken bones tree, which is distributed throughout India and South East Asia. Oroxylum indicum is known by such regional names as Bhatghila, Tona, Bhut-vriksha, Shyonaka, and Hanyu pinyin. Over the past two decades, many reports have appeared in mainstream scientific journals describing its nutritional and medicinal properties. While much of this recent enthusiasm indeed appears to be justified, it is critical to separate rigorous scientific evidence from anecdote. The present review provides the complete information about literatures of Oroxylum indicum as botanical descriptions, vernacular names, biological activity of plant parts, ethanomedicinal uses and current status of research with scope of investigation of Oroxylum indicum for future research. The structures of twenty eight isolated compounds from different parts of Oroxylum indicum with IUPAC names, molecular formula, formula weight, melting points were also reported in this study.
