| 1 | In vitro antioxidant activities of ethanol extract from Enhalus acoroides (L.F.) Royle显示文摘Objective:To search for new sources of safe and inexpensive antioxidants,the leaf,root and rhizome of Enhalus acoroides(E.acoroides) were screened for the first time for their antioxidant activities.Methods:Samples of leaf,root and rhizome from E.acoroides were tested for total phenolic content,proanthocyanidins and in vitro antioxidant activity in terms of total antioxidant assay,DPPH assay and FRAP assay.Results:The leaf sample was found to have high levels of phenolic(0.323±0.028 mg TAE/g) and proanthocyanidins(0.570 0±0.000 3 mg TAE/g) when compared to root and rhizome.The leaf samples exhibited higher total antioxidant activity (11.770±0.026 mg Ascorbic acid equivalent/g),higher percentage of DPPH radical scavenging activity(25.76±0.04) and higher reducing power(18.060±0.073) in terms of mg GAE/g.In addition, there was a significant correlation between total phenolic content and total antioxidant activity (R^2=0.923),DPPH assay(R^2=0.509).FRAP assay(R^2=0.994).Similarly,significant correlation was found between the proanthocyanidin and total antioxidant activity(R^2=0.977),DPPH assay (R^2=0.464) and the FRAP assay(R^2=0.998).Conclusions:These results suggested that E.acoroides have strong antioxidant potential.Further study is necessary for isolation and characterization of the active antioxidant agents,which can be used to treat various oxidative stress-related diseases. | Rengasamy Ragupathi Raja Kannan Rajasekaran Arumugam Perumal Anantharaman | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，11： | 15 |

| 3 | Antimicrobial potential of selected brown seaweeds from Vedalai coastal waters,Gulf of Mannar显示文摘Objective:To evaluate the antimicrobial activity of Turbinaria conoides(T.conoides).Padina gymnospora(P.gymnospora) and Sargassum tenerrimum against human bacterial and fungal pathogens.Methods:The antimicrobial activities of the extracts against various organisms were tested by using disc diffusion method.Results:The methanol extract showed the better result than the other extracts.Whereas,the strong antibacterial inhibition was noted in methanol extracts of P.gymnospora against Bacillus subtilus(26.33±1.86) and the mild inhibition of ethanol extracts from T.conoides against Klebsiella pneumoniae(2.33±0.51).Acetone extraction of P. gymnospora had strong antifungal inhibition against Cryptococcus neoformans(23.00±1.78), and acetone extract of T.conoides had mild inhibition against Aspergillus niger(3.00±0.89). Conclusions:The seven different solvent extracts of seaweeds used in the present study have shown significant bacterial action.Further,a detailed study on the principle compound in the seaweeds which is responsible for antimicrobial activity is still needed and it can be achieved by using advanced separation techniques. | Manivannan K Karthikai devi G Anantharaman P Balasubramanian T | 2011 | Asian Pacific Journal of Tropical Biomedicine2011，1，2： | 9 |
| 4 | Antibacterial potential of three seagrasses against human pathogens显示文摘Objective:To evaluate the antibacterial activity of Halophila stipulacea(H.stipulacea), Cymodocea serrulata(C.serrulata) and Halodule pinifolia(H.pinifolia) against seven human bacterial pathogens.Methods:The antibacterial activities of the extracts on the various test organisms using disc diffusion method and Minimum Inhibitory Concentraction(MIC).Results: Methanol and chloroform extracts of all the three seagrasses were active against all the tested pathogens,whereas the hexane extract of seagrasses was not active against Staphylococcus aureus (S.aureus).Antibacterial activity of three seagrass screened,was in the order of H.pinifolia > H.stipulacea.> C.serrulata.Conclusions:This antibacterial studies can further investigated on seagrasses for purification of bioactive substance and its possible utility in disease control. | Rengasamy Ragupathi Raja Kannan Rajasekaran Arumugam Perumal Anantharaman | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，11： | 7 |
| 5 | In vitro antioxidant activities of selected seaweeds from Southeast coast of India显示文摘Objective:In vitro antioxidant activities of three selected Indian seaweeds viz.,Halimeda tuna(H.tuna),Turbinaria conoides(T.conoides) and Gracilaria foliifera(G.foliifera) were evaluated.Methods:Total antioxidant activity,total phenolic content,and reducing power of crude methanol and diethyl ether extracts were determined.Results:Total phenolic content and total antioxidant activity were higher(1.231±0.173 mg GAE/g,1.675±0.361 mg GAE/g) in T.conoides respectively.Reducing power of crude methanol extract increased with concentrations of the extract.The Fourier transform-infra red spectrum analysis revealed the presence of polyphenolic signals.The seaweed extracts displayed moderate antioxidant activity compared to gallic acid standard.Conclusions:The seaweeds could be considered for curing diseases from oxidative deteriorations. | Gopalraj Karthikai Devi Karunamoorthy Manivannan Ganapathy Thirumaran Fatimson Arockiya Aarthi Rajathi Perumal Anantharaman | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，3： | 6 |
| 6 | Hepatoprotective activity of brown alga Padina boergesenii against CCl_4 induced oxidative damage in Wistar rats显示文摘Objective:To investigate the protective effects of brown alga Padina boergesenii(P.boergeseii) against carbon tetrachloride(CCl4) induced oxidative damage and liver fibrosis in rats.Methods: To assess the hepatic damage liver weight,the activities of TBARS level,glutathione,SOD,CAT and GPx in circulation and liver.Results:The group of rats induced with CCl4 alone(2 mL/kg body weight),showed noticeable increase in the liver weight and TBARS level.Followed by, the level of antioxidant enzymes glutathione peroxidase,Superoxide dismutase and catalase was also significantly(P<0.01) diminished.Where as,the rats pretreated with P.boergesenii(150 mg/ kg body weight) modulated the CCl4 induced liver fibrosis.The level of antioxidant enzymes and lipid peroxidation products was found to be significandy(P<0.01) attenuated to near normal level, when compared with rats induced with CCL,alone.In order to assess the role of carotenoids in the relevant activity,total carotenoid content of the extract was analysed and found to be 0.59 mg/g fresh weight(FW).Further,the histopathogical studies provide a supportive evidence for this study to show the protective nature of P.boergesenii.Conclusions:The protective role of brown alga P.boergesenii extract has confirmed its potential activity through its antioxidant sparing actions against CCl4 induced free radical damage.However,the possible mechanism of hepatoprotection is rather speculative at this stage and investigations are underway to isolate and characterize the bioactive compounds from P.boergesenii. | Rajamani Karthikeyan ST Somasundaram T Manivasagam T Balasubramanian P Anantharaman | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，9： | 6 |
| 7 | Techno-economic comparison of three technologies for precombustion CO2 capture from a lignite-fired IGCC显示文摘This paper compares the techno-economic performances of three technologies for CO2 capture from a lignite-based IGCC power plant located in the Czech Republic:(1)Physical absorption with a Rectisol-based process;(2)Polymeric CO2-selective membrane-based capture;(3)Low-temperature capture.The evaluations show that the IGCC plant with CO2 capture leads to costs of electricity between 91 and 120€·MWh−1,depending on the capture technology employed,compared to 65€·MWh−1 for the power plant without capture.This results in CO2 avoidance costs ranging from 42 to 84€·tCO2,avoided−1,mainly linked to the losses in net power output.From both energy and cost points of view,the low-temperature and Rectisol based CO2 capture processes are the most efficient capture technologies.Furthermore,partial CO2 capture appears as a good mean to ensure early implementation due to the limited increase in CO2 avoidance cost when considering partial capture.To go beyond the two specific CO2-selective membranes considered,a cost/membrane property map for CO2-selective membranes was developed.This map emphasise the need to develop high performance membrane to compete with solvent technology.Finally,the cost of the whole CCS chain was estimated at 54€·tCO2,avoided−1 once pipeline transport and storage are taken into consideration. | Simon Roussanaly Monika Vitvarova Rahul Anantharaman David Berstad Brede Hagen Jana Jakobsen Vaclav Novotny Geir Skaugen | 2020 | Frontiers of Chemical Science and Engineering2020，14，3： | 3 |
