Spectrophotometry for Determining Content of Hesperidins in Peels of Citrus

The content of hesperidins in peels of citrus has been determined by spectrophotometry.The maximum wavelength of color system is in 422nm. The apparent molar absorptivity is 4.21×10 4L· mol -1·cm -1.Beer's law is obeyed in the range of 0-60μg/mL. The method is convenient and reliable,with satisfactory results.
