Establish a rapid determination of an analytical assay of astaxathin were desgned from chemi-cal synthesis by spectrophotometry. Using chloroform as extraction solution treated by hydroquinone,under 489nm wavelength determination of absorption.The spectrophotometric method of standard curve regression coefficient is 0.9999. the relative standard deviation is 0.36%, the standard addition recovery is 99.8%~102.5%, show that the analysis method of high accuracy, good repeatability, and is simple, rapid, and can be used as an enterprise with the determination of astaxanthin in mass production.
