| 1 | phytochemical analysis and in vitro antioxidant acitivity of hydroalcoholic seed extract of Nymphaea nouchali Burm.f.显示文摘Objective:To evaluate the phytochemical constituents and the antioxidant activity of hydroalcoholic extract of Nymphaea nouchali seed locally prescribed as a diet for diabetes mellitus.Methods:The antioxidant and free radical scavenging activity of hydroalcoholic extract of the plant was assessed against 1,1 diphenyl-2-picryl hydrazyl(DPPH),nitric oxide and lipid peroxidation using standard protocols.Total phenolics,flavonoids and tannins were also determined.Results:Phytochemical analysis revealed the presence of phenols,flavones,tannins,protein,reducing sugars,glycosides,saponins,alkaloids and steroids.The activities of plant extract against DPPH,nitric oxide and lipid peroxidation was concentration dependent with IG_(50)value of42.82,23.58 and 54.65μg/mL respectively.The total antioxidant capacity was high with 577.73 mg vitamin E/g of the extract and showed a moderately high vitamin C content of 197.22 mg/g.The total tannin content of hydroalcoholic seed extract was high(195.84 GE/g),followed by phenolics(179.56 GE/g)and flavonoids(23.55 QE/g).Conclusion:Our findings provide evidence that the crude extract of Nymphaea nouchali is a potential source of natural antioxidants and this justifies its use in folkloric medicine. | Mabel Parimala Francis Gricilda Shoba | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，11： | 2 |
| 2 | Design and analysis of multi-channel drop filter using dual L defected hexagonal photonic crystal ring resonator显示文摘In this paper,dual L defected hexagonal Photonic Crystal Ring Resonator(PCRR)using Channel Drop Filter(CDF)is designed for Coarse Wavelength Division Multiplexing(CWDM)systems.In this structure,the external rods of the ring resonator are arranged in a hexagon and the internal rods are removed in L arrangement for introducing defects.Scatter rods are used to prevent leakage.By using the L defected hexagonal resonator,a multi-channel CDF is designed,which exhibits multiple wavelengths of CWDM(1500 nm–1600 nm)region.In addition,the selection of rod size and the position of rods in the proposed multi-channel CDF are validated by varying the radius of coupling and scattering rods,as well as the position of resonators,respectively.By using plane wave expansion and opti Finite Difference Time Domain(FDTD)method,the electromagnetic wave propagation and the photonic band gap are obtained. | D.Saranya Shoba Mohan A.Rajesh | 2020 | Digital Communications and Networks2020，6，1： | 2 |
