Optical and gamma irradiation studies of morin in ethanol

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 (e) 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.
