Isolation, identification, and antioxidant activity of polysaccharides from the shell of abalone (Haliotis discus hannai Ino)

Z. L. Wang, Liang, H. B., Guo, W., Peng, Z. F., Chen, J. D., and Zhang, Q. Q., “Isolation, identification, and antioxidant activity of polysaccharides from the shell of abalone (Haliotis discus hannai Ino)”, vol. 13, pp. 4883-4892, 2014.

In this study, two antioxidative substances, a homogeneous polysaccharide [abalone shell polysaccharide (ASP-1), corresponding to the first peak by size exclusion chromatography] and a non-polysaccharide compound [abalone shell compound (ACS-2), corresponding to the second peak by size exclusion chromatography], were extracted from the abalone (Haliotis discus hannai Ino) shell. We primarily focused on the investigation of ASP-1.

Assessment of genetic diversity of landraces of Dendrocalamus hamiltonii using AFLP markers and association with biochemical traits

S. D. Waikhom, Ghosh, S., Talukdar, N. C., and Mandi, S. S., “Assessment of genetic diversity of landraces of Dendrocalamus hamiltonii using AFLP markers and association with biochemical traits”, vol. 11, pp. 2107-2121, 2012.

Fermented bamboo shoots are popular traditional food items of various ethnic groups of the northeastern India, especially in Manipur State. Dendrocalamus hamiltonii is an economically important bamboo species used to produce fermented bamboo shoots. We studied genetic variability of this bamboo species in Chandel and Imphal-East (commercial production districts), using AFLP molecular markers. Each of the selected primers detected polymorphisms and 1614 (95.8%) were found to be polymorphic.

In vitro antioxidant activities of endophytic fungi isolated from the liverwort Scapania verrucosa

P. Y. Zeng, Wu, J. G., Liao, L. M., Chen, T. - Q., Wu, J. Z., and Wong, K. - H., “In vitro antioxidant activities of endophytic fungi isolated from the liverwort Scapania verrucosa”, vol. 10, pp. 3169-3179, 2011.

We investigated in vitro antioxidant activities of 49 endophytic fungi isolated from the liverwort Scapania verrucosa. Based on morphological and molecular identification, the endophytic fungi isolated were classified into seven genera (Hypocrea, Penicillium, Tolypocladium, Chaetomium, Xylaria, Nemania, and Creosphaeria), all belonging to one family (Xylariaceae).

Effects of immature cashew nut-shell liquid (Anacardium occidentale) against oxidative damage in Saccharomyces cerevisiae and inhibition of acetylcholinesterase activity

S. G. De Lima, Feitosa, C. M., Citó, A. M. G. L., Neto, J. M. Moita, Lopes, J. A. D., Leite, A. S., Brito, M. C., Dantas, S. M. M., and Cavalcante, A. A. C. Melo, “Effects of immature cashew nut-shell liquid (Anacardium occidentale) against oxidative damage in Saccharomyces cerevisiae and inhibition of acetylcholinesterase activity”, vol. 7, pp. 806-818, 2008.

The cashew tree (Anacardium occidentale) represents one of the major cheapest sources of non-isoprenoid phenolic lipids, which have a variety of biological properties: they can act as molluscicides, insecticides, fungicides, have anti-termite properties, have medicinal applications, and demonstrate antioxidant activity in vitro. Immature cashew nut-shell liquid (iCNSL) is a unique natural source of unsaturated long-chain phenols. Their use has stimulated much research in order to prepare drug analogues for application in several fields.
