background: glycowithanolides (withaferin a), is one of the main withanolides active principle isolated from plant withania somnifera and is claimed that it possess the aphrodisiac, sedative, rejuvenate and life prolonging properties. objective: in the present investigation, antioxidant activity of active principles of withania somnifera was tested against d-galactose induced oxidative stress i...

Abstract. RAMSES is the operational spectrometric fluorescence and Raman lidar at Lindenberg Meteorological Observatory. It employs three spectrometers, with UVA spectrometer (378–458 nm spectral range) being latest to be implemented in 2018. The extends measurement range shorter wavelengths than previously accessible, its water vapor measurements can corrected for effects. First new experiment...
