| 1 | Antioxidant activities of Indigofera cassioides Rottl.Ex.DC.using various in vitro assay models显示文摘Objective:To evaluate the antioxidant potential of methanolic leaf extract of Indigofera cassioides(MEIC) using various in vilro antioxidant assay systems.Methods:Antioxidant and free radical scavenging activity of MEIC was assayed by using different in vitro models like ABTS, DPPH,nitric oxide,superoxide,hydrogen peroxide and hydroxyl radical.Reductive ability of the extract was tested by the complex formation with potassium ferricyanide.Further total phenol and flavonoid contents of the crude extract were also determined.Rutin and ascorbic acid were used as standards.Results:MEIC exhibited potent and concentration dependent free radical scavenging activity in all the tested models.Reductive ability was also found to increase with increase in MEIC concentration.Total phenol and flavonoid content determination showed that the extract is rich in phenols and flavonoids.Conclusions:All the results of the in vitro antioxidant assays reveal potent antioxidant and free radical scavenging activity of the leaves of Indigofera cassioides,equivalent to that of standard ascorbic acid and rutin.This potent antioxidant activity may be attributed to its high phenolic and flavonoid contents. | R Senthil Kumar B Rajkapoor P Perumal | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，4： | 15 |
| 2 | Seasonal variations of phytoplankton diversity in the Coleroon coastal waters,southeast coast of India显示文摘The results of an investigation carried out during June 2005 to May 2007 on physico-chemical parameters,species composition and community structure of phytoplankton including Chlorophyll a(Chl-a) at the Coleroon coastal waters(Southeast coast of India) are reported.Air and surface water temperatures(°C) varied from 25.1 to 30.1 and from 24.5 to 28.5 respectively.Salinity values varied from 6 to 28.5 and the pH ranged between 7.0 and 8.3.Variation in dissolved oxygen content was from 3.1 to 7.5 mg/dm-3 while the light extinction coefficient values(LEC) ranged between 3.1 and 10.1 cm.The ranges of inorganic nutrients(μmol/dm-3) viz.,nitrate,nitrite,phosphate and silicate were 10.1-23.4,1.2-8.9,0.2-3.1 and 55-125,respectively.The ranges of Chlorophyll a(μg/dm-3) values was 2.0-7.5.Presently,124 phytoplankton species representing different classes viz:Bacillariophyceae(77),Dinophyceae(19),Cyanophyceae(15),Chlorophyceae(10) and Chrysophyceae(3) were recorded.The phytoplankton cell abundance varied from 0.290 to 111.662 cells/cm-3,with peak diversity(3.38 bits/ind.) during summer season.The maximum abundance was found during summer season coinciding with the stable hydrographical conditions.The seasonal distribution and abundance of phytoplankton are discussed in relation to hydrographical parameters.Canonical Correspondence Analysis(CCA) was applied in this paper for discriminating environmental factors having effect on phytoplankton community at species level.Coleroon coastal water is subjected to long term fluctuations in physico-chemical parameters depending upon the seasonal tidal amplitude and freshwater influx resulting in a continuous exchange of organic,inorganic,plant and animal matters. | Thillai Rajasekar K Rajkumar M SUN Jun Ashok Prabu V Perumal P | 2010 | Acta Oceanologica Sinica2010，29，5： | 3 |
