Figure 2

Graph of the fluorescence spectra of the upper phases (UPs) and lower phases (LPs) of the C. andromeda extracts from the umbrella (UMB) and oral arms (OA), measured in the range from 280 to 850 nm (excitation wavelength 230 nm, wavelength step size 2 nm) in polar organic solutions. Blanks were acetonitrile for UP and water/acetonitrile for LPs.
