| Abstract: | A method for the TLC-densitometric determination of neomycinA has been established. The sample solution was spotted on silica gel G platetreated with 0.3mol/L NaOH and 0.01mol/L KH_2PO_4 and developed by methanol-chloroform-ammonia water(2:1:1). Spots were visualised with ninhydrin systemand determined by dual wavelength TLC scanner.The recovery is 100.9%. RSDis 0.9%. |
