Abstract
Spectral studies of morin in aqueous ethanol and other alcohols have been carried out as a function of its concentration and that of ethanol, and the pH of aqueous buffer. The effect of gamma radiations on morin solution in ethanol was also studied as a function of dose in the range of 0.15-2.28 kGy and of morin concentration (10-5-10-4 mole·dm-3). Morin concentration in ethanol solution showed a linear response for G values to a dose of 1.83 kGy. Molar absorption coefficients (ε) for morin in ethanol have been estimated to be ∈260nm=2.28·104 dm3·mol-1·cm-1 and ∈291nm=8.22·103 dm3·mol-1·cm-1 for unirradiated and ∈291 nm=1.75·104 dm3·mol-1·cm-1 for irradiated solutions to a dose of 1.83 kGy.
